How to Fix Errors and Format USB Flash Drives

How can you quickly fix and format your USB flash drives and make it functional again for optimal use. USB flash drives are a great data storage and safe data transfer gadget. But if you believe that flash memory is secure and stable forever, you are wrong.

usb flash driveFlash memory is considered insulated from jerks and related damage. However, these USB pen drive do get corrupt as I noticed. I use a top branded USb pen drive and am using it for the last 6 months and it worked very well. (Never rely on cheap unbranded usb drives – you never know when your data is lost)

So of late, when I started to open my powerpoint presentations, they would not open. Some error had occurred during transfer or storage as the main file from which it was transferred worked well. So the problem was in a data storage as the transfer was smooth.

Fix USB Flash Drives

An important precaution is not to remove the pen drive while the data is being transferred. Always remove the pen drive after stopping it. Go to ‘Safely remove hardware’ (green arrow icon art bottom right corner).

Safely remove drive

Stop the usb mass storage drive and when it says it is safe to remove it, then remove it.

remove hardware

Always check by opening your important files before that important presentation. If it does not open now, probably it will not open there also. If it works now, it should work there also.

If for some reason your file does not work. Transfer another copy of the file with a renamed version – it may work..

If you delete the file and retransfer the same file with the same name and size, it probably gets written to the same area and will not work. A different name with a different size gets written to another area and can work. Its better to transfers 2 copies of your file anyway.

If you want the presentation to work on older computers (like Windows 98), do not forget to take the drivers CD which will allow such computers to recognize your plug and play usb drive. Always keep this invaluable CD handy, you never know when you encounter an older computer. I also keep a copy of the Wind 98 driver on the USB drive, can become useful one day.

Flash drive data still getting corrupted

After going to My Computer, Right click the Removable drive, Go to Properties >Tools. Run Error Checking and Scan for errors and fix them. The files that are corrupt or in bad sectors already will not work but at least the new transferred files should work.

error checking

Format USB drive.

Remember formatting flash drives will delete all the data from your USB drive and make it fresh and hopefully remove all errors. The software for formatting comes on the CD or available on support sites for your branded usb drive on the net. For some reason, when I ran this formatting software, it would say the USB drive is not connected.

How did I format my flash drive?

Right click removable drive and select and format the drive. Then scan and fixes all errors.

Format Drive

In the File System drop down, you will see FAT and FAT32. So which one to select?

If you right click Removable Drive >Properties

Drive properties

The General Properties of the USB drive reveals it is FAT, so I use FAT in the format utility. Then just select “Quick Format” and “Start” and all data will be deleted and hopefully all errors are now gone.

If still none of these tips work – Get hold of the warranty and get it fixed from customer support. If all fails…. its time to buy a new high memory storage USB drive !

WARNIN: Please try this at your own risk. You may land up deleting all data or making your drive unusable. Seek professional help if needed.

    This is actually a really useful thing.

    I’ve had name-brand flash drives not always copy the data, and I’ve seen corrupted data be recoved by Windows. If this helps at least one person recover that vital data, then it was all worth it.

    So, thank you for sharing your experience.

  2. Anonymous says:

    Deleting and then recopying the file will most likely not copy to the same area of the disk. Flash memory has internal mechanisms that distribute data so that one area is not used more often then others; this improves the lifespan of the memory.

    After pulling a USB stick out during boot of a PC, before Windoze had started, I found it was no longer readable. OK, no biggie, only non-critical data was lost. However I could NOT re-format the drive, Windows would fail at the task. I feard the stick was dead until I formatted it in a few seconds as a FAT drive using Linux!

    I bought a Lexar JumpDrive 512 and was horrified to discover that while I could read and write to it just fine, I was forced to use 8.3 style filenames.

    Turns out it was formatted in FAT, not FAT16. I reformatted it from windows file explorer just like it was a hard drive, and it’s worked perfectly ever since. I copied the autorun folder and it’s files back onto it afterwards, and it even installs the secure partition driver upon insertion.

    i have an usb flashdrive (centrios, 256mb)..
    its not even 6 months old and its not working..
    i tried to format it but it doesnt work..
    the thing that finds and corrects all errors on the flashdrive doesnt work either..

    Recently a friend gave me a flash drive to test (verify) it.
    As the documentation sais it’s a
    SONY Micro Vault USM8024 Mass Storage Device with a capacity of 8 GB!!!, with an
    unbeliveable low price of under 90$.
    It was suspicious at first, of course, so I plugged it in, and the system (Win XP OS)
    recognized it, installed the drivers automatically, and reported the capacity of 8 GB!
    When I re-connected the device, the system reports that everithing is O.K. but
    when I attempted to access the drive reported ” There is no disk in the drive”.
    I opened the properties to see the volume information which is reported UNKNOWN.
    I could,t format it under Windows, and it’s own disk formatter could’t access the drive too.
    If someone had an experience with a drive like this, i coluld use a help.
    Or, be carefull if someone offers you a flash drive like this!!!
    It may NOT be an authentic SONY product!!!

    SONY 8G Model USM8024 appears to be a FAKE. There are loads of these selling on EBAY, but they do not work (atleast with Windows XP Pro) When I contacted SONY support they told me the model was not valid and that the unit was likely a counterfeit. Hope this sways others away so they don’t get burned like I did. Buyer beware !

    I also had a usb flash drive that gave me a write protected error message when I tried to access it. I tried to format it using windows utilities and also the HP usb storage format tool. Still no luck. I was about to just trash it since it was just 128mb but then I went to the command prompt and formatted it there. Good luck

    Admin Tools didn’t work for me. I formatted the hard drive, then removed the device, but when I plugged it back in windows said the device was working properly, but computer manager couldn’t read the drive…Definately a rip off (we bought it in China though, only cost $6)

    I also was duped with the 8G Sony drive on eBay. It is as fake as it gets. They are REAL USB drives, cheap 128MB or 512MB drives with a driver that tricks Windows into thinking its 8G. The drive works flawlessly until the maximum storge limit is reached. Then all files added show up as 000.0000000 and FORMAT is the only way to make it usable again.

    I filed a formal report to Sony and they confirmed that world wide Sony makes nothing bigger than a 2GB USB Memory Vault. ALL 4G and 8G drives are fake, with fake packaging, manuals, the works…

    So quit looking for a “fix” or a way to make the drive bigger, it does not have the space to begin with!

    Ok that’s all fine if, when you format the capacity of the flash drive is known.

    But, in my case when I try to format it, there is no capacity recognized, and when I mount it on the system I receive the message of “Please insert disk into drive ….”.

    Is there any possibility to recover from such a case?

    Dear All,

    I’ve been using a SanDisk Cruzer Micro flashdisk for 9 months. Just recently it sends a “Device I/O Error” when I try to copy anything to it. It’s still being found by the OS and I can read the data but very slowly. I already tried every solution that is presented here and all failed. however when I formatted the drive frm command prompt it returned an “Invalid media or Track 0 bad” error. does it mean that I should trash it and buy another one? Please some pro give me some suggestions.

    Hello. I think i have the same problem as Scott Harrisson, person leaving comment number 32. Computers could’t read my flash drive anymore, it’s an iMax 256mb. My friend thinks it got burned, and i do think too, because it got too hot it scathed my skin as i removed it from the USB port. The desktop did’t read my flash disk in the first place, nor my camera.

    I have a one very important question: Is the chance that i can retrieve my data?

  56. Chris W says:

    The problem with the counterfeit Sony drives is not just the 4&8 GB. My buddy brought back a bunch of 1GB drives from China. They are really 512MB drives. Note that when you reformat, sometimes Windows will clue you in and say after formatting that 512MB is already used space, with 512 free. However when you use the “quick format” check box option, it doesn’t detect it, and says you have 1GB free. You can add data until you reach the halfway mark, then it says “sector not found” or whatever. Clever. Someone needs their ass kicked for this.

    I recently had a Crucial Gizmo 128MB flash drive which developed the ‘Please insert disk’ problem after I installed a new HP PSC2355 printer (it had worked perfectly previously). I tried the re-format option mentiond and the drive formatted ok (win XP). I still got the ‘Please insert disk’ problem though. I noticed that when I right clicked on the pen drive in Windows Explorer and selected ‘Explore’ the contents of the next drive down the list were displayed. I then changed the drive letter for the pen drive (right-click my computer > manage > right-click the drive in question > Change Drive Letter and Paths. It has worked ok since then! Note that the drive letter I used was not the next available (I had C: – E:, M: – P:, so I used ‘K:’ for the pen drive. Maybe I was just lucky, but hopefully this might help resolve the problem for someone else.

    Hello Everyone
    i had a 512 Mb usb drive
    iam trying to load data, or deleting the existing data , it shows an error saying that disk is write protected,
    Please help me
    Thanks in Advance

  89. Zulf says:

    your USB drive is ‘write-protected’. to stop this there is:
    1. a little switch on your drive whoch you can move
    2. software protection which can be removed following the instructions in the software itself.

    If that doesn’t help post the make/model of the usb drive pls!

  93. JS says:



    As far as I know, a quick format doesn’t format the whole volume (disk, pen), only erases the FAT — that’s why it is quick! I’m thus pretty sure it won’t detect bad sectors.

    If you wish to format a volume to detect bad sectors, you must perform a full formating. Isn’t it so?


  94. azzie23 says:

    My flash drive stopped displaying in explorer – hardware working but can’t access it. Ran diskmgmt.msc and the drive was displayed but with a drive letter already in use. Changed the drive letter to an unused one and now it appears in explorer.Hope that helps someone.

  96. Morteza says:

    I also was duped with the 8G Sony drive on eBay. It is as fake as it gets. They are REAL USB drives, cheap 128MB or 512MB drives with a driver that tricks Windows into thinking its 8G. The drive works flawlessly until the maximum storge limit is reached. Then all files added show up as 000.0000000 and FORMAT is the only way to make it usable again.

    Thank you to ‘inforisk’! I used the HP driver and fixed the flash drive I had inadvertently formatted (forgot to remove it from the machine I was rebuilding) it was my husbands flash, so I am very happy to recover it!

    A year ago I got a HUKE platinum drive, and yesterday, by mistake I tried to use it in a PC with windows 98, I unppluged the memory and when I tried to use it in another PC (windows XP) I got a window asking me to format the device, so I tried and got another windows explaining that windows was unable to format the usb (something like Mauricio said). Is there a way to fix this or my usb memory is DEAD. Help!

  106. Manish says:

    Hi guys,
    Now I wonder why didn’t I come to this site before.
    Well, my situation isn’t really that worst but yesterday I bought a cheap usb flash drive / mp3 player (fake SONY 2GB).
    Sometimes it works fine but, here’s what I have noticed while playing around with it.
    1) It show 2 partitions, 1st with 1.86 GB and 2nd with 1 MB. 1st can be formatted fine and 2nd gives error.
    2) If you copy multiple folders at a time, some files gets corrupted.
    3) If you create a new folder manually, it can’t be deleted and there are lots of garbage files inside it.
    4) Once, a file is copied fine, it works fine only.
    5) Transfer rate is much slower than Transcend (which I used before).

    So guys, my recommendation is that, please don’t go for cheap flash drives. You never know what you may losse. Let’s see how long it works and then I am gonna get a flash drive not less than Transcend or Creative.

  113. chaz says:

    I had the same problem with my cruzer micro 1 GB, i solved it with the following.

    Try right clicking on My Computer, Select Manage,
    expand Computer Management and then select Disk Management( in the storage part).
    Choose your 1 gig drive,
    Delete the partition and make a new one again, i made the partition the same size as the drive, then format it as FAT.

    hopefully this should work for you as it did for me,

    my drive no reads 973MB but not sure what it read before it corrupted.

I have to unplug it as normal or an air message appears noting that I should do this. I have many documents on this drive, thus, how can I access it? Thank you for this very important help.

  120. david says:

    I doubt anyone can help me but maybe someone can. My problem is (i think) different from anyone elses. Upon turning my mp3 player on it says “Error! Reformat Media” – which is fine but whenever I plug the thing into my PC (or any PC … or even a Mac for that matter) the host system freezes up when attempting to access the drive. Therefore it doesn’t appear as a drive. But as soon as I unplug it, everything unfreezes. It wants me to reformat but i can’t because no computer in the world will let me access it!! The only thing i haven’t tried is linux, which i will try soon. any ideas??

  128. Steve says:

    Just a thnk you to this site for helping out with a PNY Attache 512mb which suddenly became unreadable by XP. Using disk management and reformatting in FAT32 worked great. I’m decent with computers, but it never would have occurred to me to use XP’s own disk management system for the fix. Thanks to all who help out here.

    Hey recently bought a usb flash mp3 player but when I put it in the comp it says I have to format it. When I say yes or no it doesn’t do anything. Any answers from anyone or should I just through the thing away?

  130. Manu says:

    To all unfortunates who were cheated………………(I am one of them..)

    If you bought a high capacity flash disk mp3 player and after formatting the size has been reduced, its most likely that u have been cheated by the vendor. The flash chip inside will be of lower size. They modify the firmware to show higher size to the operating system(like 2gb, 8gb etc). Once you format, that modification is somehow gone and it will show the original size. (Less than original size actually, because the firmware takes some space). You can confirm if you open the player and check the flash disk part number.

    I bought 2gb mp3player which showed 2gb when i checked in pc at the shop itself. but once i formatted, it has become 482 mb. i opened it and the flash chip inside is 512 mb. So the best way to check whether it is 2gb is to copy 2gb data at the shop itself.

  131. cakey says:

    Hi everyone. I use a Sony 4G Mp3 player (not genuine I guess)
    A few things I’ve noticed to make it work properly:
    Look in the settings on the player itself and make sure the “online mode” is set to normal (not encrypted or multi drive)
    Also, when copying files to them don’t drag folders across (only drag files)
    I hope this can help some people

    Formatting a flash memory device!!!! I don’t agree with you there. Manufacturers issue strict warnings against formatting flash drives. I once formatted my Sony Micro-Vault and it became unusable. It was only after I reformatted it using a special tool from Sony that it became usable again.

    Its so dangerous to flash USB device. I agree with Atul. It can cause permanent damage to the device. Not that i have personal experience in that, but my friend had.. just my 2 cents.

    Tried the makers lock / unlock program and formatter, but still no good. Tried the HP formatter (sp27213), same. Now downloading the bigger hp program.
    Not holding out much hope, its not even fit to be used as a suppository! Seems like they are all a bit unreliable.

    With a Sandisk Cruzer Freedom 1.0 Gig drive, I started getting ‘the drive is not formatted’ errors, and it would consistently fail to format no matter how I did it. The drive worked fine on other computers.

    The same computer was having the problem with several other flash drives, but NOT any problem with my Memorex 1Gig drive which automatically assigned drive letter K (rather than F that all the others used.)

    I found that reassigning the drive letter to something other than F (I chose drive I) fixed the problem! In Windows XP, this can be easily done by right-clicking ‘My Computer’, choosing ‘Manage’, then click ‘Disk Management’ under storage — right click your flash drive in the lower right corner (be sure to choose the right one) and choose ‘change drive letter and paths’

    Just a tip in case it helps anyone else :)

  182. Shepherd Nhongo says:

    I have relied on linux RedHat Advancd Server 4.0 in solving flash disk formatting. I have formatted the USB in ext3 format similar to FAT system.

    Hope you will find it useful…

    Try any other LINUX it should be ok…

    Give me feedback

    I purchased SONY NS-11 512MB mp3 player last month.After formating the player its memory came down to 119 MB tothat of 512 MB, i dont know how to get it back to 512MB, its still working with a memory of 119MB,
    hope any one of you have a solution to this.if you have a solution please mail me.
    i am satisfied wit its battery life and sound quality but where the hell is memory!!!
    its easy to use and download songs and delete songs. the manual book is useless.
    you have to scratch ur brain a lot to understand it. but once you understand the opperations, its very easy to use. i have also managed a software to compress the mp3 songs to 1/5th of its memory, a 5MB song can be easily converted to 1MB.
    This gave me some relief after I lost the memory of my player. still i can store around 100 songs in my player.

    is usb properly configured?

  232. Annonymous says:

    I’m encountering the same problem as the others having 8GB flash drives with the only difference that i”ve IBM 8GB flash drive, infact 2 drives. My experience is that; at first the drive was shown properly in Winxp Pro with correct size of 8Gb. when I started transferring data it stopped transfer after sending about 2Gb. Then i entered the drive; but found no files in there. when I wanted to enter the drive 2nd time I couldn’t. Now it gives error ” Insert Disk in Drive X:” in roperties capacit used “0 bytes” available “0 es”. I can’t evern format it. same is the case when i try to acces it from winxp disk management.
    so I would suggest not to buy 8Gb flash drives. coz same is the problem with all 8GB flash drives and when you search it on the net u’ll find only
    1GB, 2GB and 4GB flash drives most of the time.
    so 8GB is just a hoax and fraud.

  254. Radji says:

    This behavior is related to the system to witch the drive is pluged ,to ensure that try another PC
    the drive will be writable.
    this problem is due to a pc lock program that protects the whole PC or drives with passwords .
    after this type of program is uninstalled before removing protection of the USB drive.the drive became write protected.
    The sollution :
    1- Remeber the program you installed recently and reinstall it. if you have forgotten or think you did install such prog at all.install another one for exemple: USB Lock AP.
    2- Form the program choose unprotect USB Drives.
    3- The Pen drive should be writable now.

    i have formatted my usb even till it shows virus when scanned by the antivirus. Why?

  271. Segun Oladipo Adewale says:

    guys i have a solution for your problem
    the only way you can solve this problem is to follow this simple tips with a raw drive problem
    1. get a windows xp cd
    2. shutdown your pc and plug in your flash drive
    3. boot ur pc from cd to where u have to install windows
    4. you will see ur flash drive listed in the drive selection window, select it and delete the current partition on it.
    5. create a partition on your flash, make sure it is 5 mb lower than the real size of the flash drive cos it will give u something like (128mb will become 128Gb) so this will be 123. enter and reboot to windows then format the drive.
    Bingo!!! its back working

    My Flash memory pen drive Transcend Jet Flash V10 was working correctly in my computer ‘Brio ba410’ with XP professional SP2 OS. Few days back while in using the USB device icon on task bar disappears and after that the LED indication on the Jet flash lit but the drive icon not come in ‘MY Computer’ or in task bar. It is not sensed at all. In the Device Manager, the USB component that is listed under USB serial bus controller (Controller or Root Hub) indicated that device is working properly and no conflict. I tried with the JetFlash in my office PIV computers with ‘W2000 OS’ and WXP it is working properly in both. I suspected that this is due to some virus attack while transferring data to my system while using the Jetflash and destroying the device driver. How I can rectify this. My system not having the internet connection. Please email the required drivers to my mail address ‘’or to ‘
    Thanks with regards.

    Ok, my problem is stranger yet…

  290. Cassey says:

    I have an mp3 player that is made off a samsung flash drive. I bought it off ebay and havent been able to get it to work. My computer knows theres some sort of drive there but everytime I click it says “please insert disk into drive g”. When I try to format it the same message comes up. What do I do? I mean it is possible its a complete peice of crap but the seller has been selling these for a long time and has had no complaints about them.

  291. solo says:

    My problem was like most of you. I hav an MP3 flash player.last night it got corrupt and failed to be reformatted. “Invalid media or Track 0 bad” msg as from DOS attempt. MY COMPUTER format also failed and LINUX couldn’t format too……so did I dumped the player?

    Ah…just chose FAT instead of FAT32 type in format command as
    format f: /FS:FAT
    and it worked…..perhaps flash drives dont support FAT32.

    Hi there

    i have been having a real problem
    my USB was plugged into 1 computer, and after saving the appropriate documents and exiting properly, i unplugged it
    i then plugged the USB into a another computer, and found that i was unable to access the files
    i tried multiple times on multiple computers to make it work but i just couldnt
    i then wondered if all my information had been erased or not
    i opened by properties and discovered that all my information was on there, taking up 931MB of 1GB
    i was still unable to access the information/folders/files

    can anyone suggest any techniques or programs or tools to help me solve my problem?

  297. LatchJohnson says:

    When you try to format through the properties in My Computer, sometimes it won’t format. Try this. Right click on My Computer, click Manage. Then click Disk Management. Even if your ubs drive isn’t showing up in explorer, it should show up here formated/partitioned or not. Delete the usb’s partition and set it up as a new primary. It will forcably format it that way without a problem. I’ve used this method many times and it has never failed me when i couldn’t do it any other way.

    bought an 8gig nonamed usb drive on ebay, first time I have gotten krap from there…….it is about 1-1/2″ overall length. teeny thing.

    POS it is, however I have to format before using every single time. Otherwise if I copy off and then start to load data again, you can see the data in WinExplorer, and verify it, and safely remove the USB drive, and the data is then gone.(shaking head)….to think I could have bought a REAL usb drive for the same $100.

    Get one of your Linux friends to format it on their system using:

    mkdosfs -c -F 32 -n NAMEIT -v /dev/sdg1

    It will find bad blocks while formating. I was SHOCKED how many bad blocks I had on mine.

    hi, i have got a 1gb mmc disk. when i plug it in, it seemed to have 2 partitions.
    The first partition’s filesystem was FAT or FAT32 and had got a capacity of ~ 1gb.

    And i can not access any of the partitions on my computer, but my mobile phone can access and use the first partition and it said my isk has one partitiion of FAT32 and 1 gb.
    I killed my disk for a solve via a program named Active KillDisk. Now my disk has 279gb of free space but still i can not access to my disk and can not format it. Please give me some advice. What must i do to take my disk back? Waiting for reply. Thanks all.

    Hi to all you people having problems with you flash drives. This worked for me, although I lost the data.
    I purchased a 4gb sony pen from Hong Kong on ebay. All was well until I overran its capacity while saving data. The result was that my win2k OS refused to recognise it as a drive and would not even let me format it in the usual way, or even from the command prompt.
    However, choosing ‘Computer Management’ from the control panel window, then selecting ‘Storage’>’Disk Management’. I them right clicked on the offending item and selected to create a partition. Part of this process enables a format operation which requires you to choose the FAT file system. After this back to Windows explorer and Bingo! there is my clean usable pen drive back in action. There is software out there that says it can restore lost files from formatted disks so there is still hope for my data so long as I do not start using the drive before trying. Good luck.

    My 1GB transcend v30 pendrive had a same problem .In properties file system seen is RAW . I ‘m not able to corect using disk manager ,statues there seen is unreadable disk. it can’t be open /explored , niether it can b formated in win xp /2k. Ihavenot tried o/s cd method.


  341. gh0st says:

    This software formats SD Memory Card and SDHC Memory Card(SD/SDHC Memory Card) using a formatting program that complies with the SD Memory Card specification SD formatting provides quick and easy access to the SD Memory Card.

    Generally, SD/SDHC Memory Card file systems formatted with generic operating system formatting software do not comply with the SD Memory Card specification.

    btw. I have an ADATA 2GB flash drive and after a couple of months use, I’ve been living like hell dragging my personal harddrive in and out of the office just to save my works.


  343. Herbert says:

    My friend have a Transcend V30 2Gb flash drive.He lost all data and when you right click properties it reads as a RAW file. What I did is check some software to recover his file. I use “EasyRecovery Professional software” to recover the file and save to another hard disk before I format the usb using “HPUSBFW.EXE” HP USB Disk Storage Format Tool with DOS System files Software to make a simple USB bootdisk.

    I tried disk management and windows format but not working for the USB.

    You try this it works for me. My friend now is happy because the USB is working and retrieve all the data. nothing is loss.

    Good Luck!

  349. Lizette says:

    I have a 2gb Micro SD and my problem is that it is malfunctioning because it cant be formatted and I’ve tried to use my own methods and these methods in fixing this but still…. *sigh*

    Whenever I store something, it just disappears but then it still consume the same space as it did when I have stored something.

    This started when I was transferring video clips from the Micro SD then a window popped out of nowhere that said ” Parameter is Incorrect” then it hang up. I closed it and ended its process, and opened it once more to find out that the files are corrupted and I cant open the MMC anymore. Hoping to recover my files, I formatted it and installed different programs that promised they can recover different files from formatted MMCs. SO Ive tried it and none worked. At least I think one or two worked but they’ve also said that the parameter is incorrect.

    Now, I cant format the mmc, my pc cant, my phone said that it was formatted but there is still 60mb consumed though whenever i open it, it always has the message “empty”, using the Digicam, it can’t format it and was rejected.

    i have a 2 GB GENX flash disk. i did not Safly remove it so the driver is removed. i need a web site that i can down load the driver from it for free

  351. PS2 User says:

    I had my 128mb USB flash drive working fine in my Windows 98 laptop today, I pulled it out without “safely remove this device” because there is no safe removal on Win 98 anyway. Then I plugged it into my Windows XP PC and it said “The disk is not formatted, do you want to format it now?”. I can’t get to my files. When I go to the properties of the USB drive, it thinks it’s using a RAW file system. When I put it back in Windows 98 laptop, I can’t access my files there either. I restarted my computer but it still keeps doing the “disk not formatted” error.

    So I then booted my PC with a Knoppix Linux Live boot Cd to see if Linux to access the files on my USB drive but Knoppix couldn’t mount the USB drive and didn’t spot a file system either.

    Then, I plugged my 128mb flash drive into my Playstation 2 and loaded up uLaunchELF and it could read the files on my USB flash drive no problem! SMS can read the files and play the videos on my USB flash drive no problem either on the PS2. So why is it that my Playstation 2 can still use the USB flash drive like nothings wrong, but Windows and Linux are unable to understand it? So I obviously haven’t lost data, it’s all still there, the PS2 can understand it fine. Unfortunatley I don’t have a way of transferring it from my PS2 to the PC.

    So if anyone else is having a “disk not formatted” error message, try and access the USB flash drive on your PS2 with uLaunchELF or SMS.

    Why is the PS2 still able to understand the USB flash drive, but Windows and Linux can’t?

    Basic summary to all readers with this sort of problem. Two times this has happened to me with drives purchased cheaply. Sad news is that it is HIGHLY UNLIKELY that anything mentioned here will work, I have tried just about everything mentioned and had no SUCCESS. This means if you haven’t backed up your data you are probably OUT OF LUCK. DO NOT STORE IMPORTANT DATA TO ANY DRIVE THAT YOU HAVENT TESTED FULLY. That means A) write and read back several files of test data. B) read back the data on different machine or system. Check several time, different amounts up to near the claimed capacity of the drive. It has been suggested in many forums that several “dodgy” drives have been appearing on internet sales sites. You may only discover flaws in such drives after nearly filling them up with important data. You may not notice for some time so ensure you do not trust crucial data to these drives until you are satisfied… it’s BUYER BEWARE, I am afraid.

    Of the two possible solutions you can try that *may* possibly help, there are a couple of “restore data” software that can be found – both “for cost” and “open source” software is available, I have used “testDisk” with success only once, and that depended on not expecting too much. It did find files from the flash disk, but not on subsequent attempts. You need to ensure you have PLENTY of spare space on the HD to which to transfer the files. Read the documentation, and read it again before just running this software. I cannot stress enough taking care and preparartion when attempting to restore data.
    Finally, you may get lucky and retrieve some files. Your best bet may in the end be to reformat, but it’s most likely you have a damaged disk. YMMV.
    The most likely solutions are those revolving about using low-level format to reformat the disk, but this will destroy any data, and may not even wind up with a disk of the capacuty claimed – many discover the disk only is 512MB instead of 8GB as claimed.
    Finally one thing I might observe is that for disks which work on one machine but not another, it *might* be a lack of power on the USB port, try the things mentioned earlier in the forum relating to USB hardware.
    Sorry I can’t be more positive, but LEARN FROM THE MISTAKES MADE BY OTHERS, AND BACKUP! BACKUP!

  361. Mezzum says:

    Some interesting posts here. Basically what I am reading and I had already assumed is NEVER put originals on the Flash Drives for obvious reasons.

    Also note, I got an 8 GIG flash drive on Ebay, $12.50 (Yes, thats 12 dollars and 50 cents)

    I have read of many scams on these types of items, got it today, ran it through MANY tests. While it is semi-slow, it will sometimes pass the ReadyBoost test. But for 12 buck and 8G of space, I can wait a few extra seconds for the write speed. Shop around, and as always, you get what you pay for, Flash Drives are no exceptions.

    I am having problems with my usb and was wondering if anyone can help.
    When I plug in my usb flash into my computer it picks it up straight away but 5 minutes later I get a warning on my desk-top saying that it is not recognised by windows.
    I have tried it in the computers at work and in tried it in my car and I have not had any problems with it.

    I would appriciate any help in this.

    Thank you very much.

  363. Skully says:

    Generally you get the “windows cannot complete format” message when the partition itself has been corrupt. Windows now sees it as a “raw volume”, and cannot format it if it does not have a valid partition. In Windows XP or Vista, go to Administrative Tools\Computer Management\Disk Management and find the drive…Create a Fat volume, and Windows will now be able to format it.

  364. PS2 User says:

    When you buy a new USB flash drive, make sure to test it before putting your data on it. The best to use is a freeware program called Checkflash chkflsh, which writes test patterns to the whole entire drive and then reads back looking for errors. If it finds errors, then you will know the drive is faulty. You can also use chkflsh to make a backup/restore image of your whole entire drive incase of corruption.

    chkflsh can also be used to do a low level initialisation on your USB flash drive too, so its a very handy tool to have. Click on the link of my name for the chkflsh website or do a search for chkflsh.

    The way I fix mine is I buy a cheap lighter and hold it under the usb drive while its formatting. I was shocked that it worked afterwards as I was attempting to destroy it in a stupid way XD!

  374. Sundeep Mukherjee says:

    I am not a computer pro, so my knowledge is more practical.

    I had the same problem with my USB, which I could not format, nor could I erase data. It dint have any switch as well.

    After hours of fiddling with the hardware, I chanced upon to press the bottom of the drive on the broad side. There was a click sound and the hardware was ready to format and/or delete data.

    What I feel is, there is a hidden push button below the outer shell at the lower side of the USB, which on/offs the write protect feature of the drive.

  375. Victor Ganescu says:

    probable solution (tested only 15 minutes back wherein I could recover my flash drive from hardly 1 MB TO 1.96 GB,originally 2gb player) to all those friends having problem with their flash drives can be use Actve @ File Recovery software 7.1 and after installation use active @file recovery for windows option.Make sure your flash drive is connected to your system. Select your device under active file recovery window and click on quick scan and let the programme recover all you files and the flash drive original capcity.this is my first posting hope it will help all my friends out there.thanks

    I have found a way how to fix “please insert disk in drive” errors on usb drives.
    It seems to be a problem with specific drive letter, and you should change it.
    To do it:
    Go to Administrative Tools\Computer Management\Disk Management
    Select properties “drive letter” for the usb disk and switch the letter to something far like “R”
    For me it worked, hope it can do it for others as well

    i got this watcha u callit sony 8gig usb surprisingly for 950 pesos(philippines)( in US its likely to be 19 bucks). but for its low price its a heck of a deal so i purchased it immediately. at first it worked well but slow in its copying. last nyt i played a game on it then it worked well, this morning my laptop cannot read it, well it recognizes it as a usb2.0 but hell i cannot format it and i cannot open the usb. i named my usb as marc but lately this morning its removable disc. when i try to open it it says not formatted when i try to format it, it says windows cannot format. i think with its low price it cannot withstand the work. oh well,,,, good bye 19 bucks,, buyers watchout for this usb. well i think its fake!

    How I fixed mine from the whole”uable to format” thing is I went to “My Computer” icon and right clicked, manage, then disk management and in My case it showed the flash drive with a blackbar at the top so I right clicked on the drive and “create new volume” dont tick the “quick format” option and let it do it’s thing, sorry if ya got important data Your gonna loose it doing it this way but at least You’ll have Your flash drive and the ability to format it next time ;)
    If You are unwilling to loose Your data You might try searching for a USB manager program on the internet that may help You recover Your flash drive without loosing data ;)

    I have had a Memorex Flash Drive 1GB for 5 years and I’ve never had corrupt files, have never reformatted it and have never used the ‘Safely Remove Hardware’ to remove it from a computer. I have it filled up many times so if there are bad sectors there are not very many. If it is common to reformat that often I feel lucky. The don’t build them like the used to.

    i have kingston 32gb pendrive .when iam copying files some erros are occuring ,it means some files are not transferring .if it was transferred to usb drive it displays but inable to open it and not playing ,only small files such as images are opening .please help me.

  470. Leonardo says:

    Im sorry, the answer for the last comments is that your memory is a fake, the capacity showed is false, because of that the first sectors, where the three of files is (localization of the files in the device), think that have that capacity but there is no space where save the information, if you open the files, really are a sector that does not exist…

  472. Laird says:

    After placing my flash drive in the USB port I then went to my computer and clicked on the E:drive to open up the files and folders. I immediately received a screen that reads: E: Application not found. I don’t understand since upon placing the flash drive in the USB port I immediately received the green check at the bottom of the screen and a message saying that the newly inserted device was found and recognized. What is the cause of this and how do i get the USB port to allow me to open up the folders in my flash drive?

    Application not found!

    If you cannot format your USB flash drive, try to format it on an other computer. Worked with me when every attempt, described on this thread failed.
