How to Fix Errors and Format USB Flash Drives

We all have USB flash drives, pen drives, memory drives and it is a great data storage and safe data transfer gadget. But if you believe that flash memory is secure and stable forever, you are wrong.

Flash 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 512MB USb drive and am using it for the last 6 months and it worked very well. (I do not 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. Thankfully I had a back up CD. So what went wrong. Well some files opened and rest did not. 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.

WARNING: Please try all these procedures at YOUR OWN RISK. I take no responsibility for your actions. There is no surety it will work. You may land up deleting all data or making your drive unusable. I am no expert in fixing usb drives. This is just my experience of how I fixed my usb drive. It is always best to seek professional support from the manufacturer (and some advise against formatting your USB lash drive).

Some tips to fix and format your 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), stop the usb drive and when it says it is safe to remove it, then remove it.

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 on eday.

If your flash drive data is 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.

If all fails, format your drive.

It 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. So all the bad sectors are fixed and my drive has become all new and is working well now.

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

    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  |  August 10th, 2005 #

    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.

    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

    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!

  • 26. Paulo  |  November 22nd, 2005 #

    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?

    Please, please do comment on this. I hope somebody can help me with this.

    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.

    Firstival try your USB Flash drive with another Window OS a difference Computer to see it still show on …because your USB Flash drive can be reject by window OS Registry during boot or shutdown and may be you are Accidently try to remove USB Flash drive during that time when your computer hang on so long . In that case only the way is to Fix your problem is Format your new Window OS on your computer :)Good luck :)!

    I had the same problem. I first tried to reformat the player using Windows.

    This did not work for my player. I contacted the manufacturer via their website and they emailed me a program to re-install the firmware. The software for the player was basically corrupted. They sent instructions on how to install the software they sent.

    I was silly enough to believe that I could buy a Sony 8 GB USB pen drive from China for less than $100 and rave about it to my colleagues. I was able to get a techie to waste an hour trying to format it.

    The old rule if something sounds to good to be true then it isn’t.

    Doesn’t that ring so true.

    My favorite 128 MB USB drive has suddenly become a floppy drive. When inserted into any xp pc, it shows as a 1.44 mb floppy on Explorer and will not accept files in excess of that. However in Disk Management it shows up as a 119 mb FAT healthy active removable drive. If I try to reformat it, it claims that that the volume is not enabled and that the computer should be restarted, but that does not change anything.

    What goes?

    I have a SanDisk Micro Cruzer 1gb the older kind with the translucent skins. For some reason I don’t know why but in XP the drive shows up under it’s own letter, but it seems in Windows Explorer you don’t see the capacity and used/free space in the right pane like you do with hard drives. Weird thing is I used to see this info, I don’t know why now the only way to find out the capacity and space left is to right click on it and hit properties. I tried re-formatting it in FAT and FAT32 and it is the same not showing the details.

    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.

    Please help me
    Thanks in Advance

  • 92. Zulf  |  September 15th, 2006 #

    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!

  • 96. JS  |  September 20th, 2006 #



    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?

    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.

Is there a way to fix this or my usb memory is DEAD. Help!

  • 109. Manish  |  October 9th, 2006 #

    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.

    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.

  • 123. david  |  November 4th, 2006 #

    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??

    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.

  • 148. http:/  |  December 19th, 2006 #

    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.

    “The disk in Drive J: is not formatted
    Do you want to format it now?”

    Re your

    For some reason, when I ran this formatting software, it would say the USB drive is not connected.

    Had the same problem but was setup up as a Power User in XP. Once I gave myself Administrator rights was no problem - found the drive.

    sometimes you need to reboot the pc to have complete control of your unit.

    just plug the device, wait until it is recogniced then clic safe remov, but DO NOT remove the usb, restart the pc and the system will configure it appropiately, if not check the bios utilities

    is usb properly configured?

    bye have a nice day

    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.

  • 262. Segun Oladipo Adewale  |  August 25th, 2007 #

    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

  • 264. reshadat  |  September 4th, 2007 #

    Well the newer flash drives are hot swappable.That means its not necessary to stop the drive!You can take it out once the file read/write action stops.But anyways its a good idea to take precautions!

    As I try to format my flash drive, I get a warning saying that all data will be deleted. Does this mean that I will lose everything I have saved onto my drive so far? I’m afraid that this is what will happen so I canceled the action. Will someone please let me know if all files have been lost as a result of formatting flash drive? Thank you.

    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.

  • 280. solo  |  October 13th, 2007 #

    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?
    any advice would be greatly appreciated
    URLs are alos OK

    PS my USB is a DSE 1GB USB

If anyone knows how i can fix this i’d be thankfull..

  • 286. LatchJohnson  |  November 2nd, 2007 #

    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.

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.

I tried with the JetFlash in my office PIV computers with ‘W2000 OS’ and ‘W XP’ it is working properly in both. Even after I providing USB 2.0 card in my computer my pen drive Transcend Jet Flash V10 is not sensed in it. But I noticed that all other pendrives are working on it. How I can rectify this.

    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

    assuming the stick mounts as /dev/sdg1

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

    After reading all of the probs peeps on here have and tried all the solutions similar to mine. Here goes; I cannot open my usb drive neither can I explore the drive, I get told that the drive isn’t formatted would you like to? But that doesn’t work, windows cannot complete the task! I try to format using the disk mangement…same result. I then try to delete the partition but that option is grayed out. I’ve even used the HP Drive Key Boot utility and gues what…still nowt!

    Please any ideas give me an email:

    I have a really nice compact flash drive (8 GB)
    I did something wrong and now I cannot access it and delete the files on it.These darn things are very expensive and cant afford anotherone.
    I have tried formatting it in windows several times with negative results.
    I guess these things arent what they are stacked up to be.
    If anyone has any other suggestions, I would really appreciate it. email me at
    Thanks, Peter

    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.
    The second partition has the filesystem RAW and the capacity is ~279gb.
    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.

    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.

    Sad to say but, “I’ve been there”, “done that” already. and the worst thing is, i’ve lost my O.R. receipt and the container of my newly acquired flash drive. and at this point, I’m desperately looking for a software that could fix my flash drive.

    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.

    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!

    I purchased a Genx flash disk ( 4 GB smart X ) almost one month ago, I used it for some time it was very slow in coping files from and to the flash disk. So I format it using the normal windows format with fat32, after that I was using it then could not be recognized by windows, after that when I insert it in the USB and check the properties it was RAW file system and have only 8 MB in size. ???? I do not know why ???

    I have been trying to fix it but unsuccessful with my tries.

    Can some body help please

    I can’t return it because I purchased it form Abu-Dhabi, UAE, then I traveled to another country.

    Waiting for help.

    My email is:

    Thanks again
