I can't open my USB Flash Stick

 rise -
Today I put some information on my flash from two computers. On the second computer I try to eject my flash, but I can't and I just pull it out. And now I try to open it on my computer but I can't. Windows is taking a massage. I have two options - Format and Cancel. I click on Cancel and try to open the flash from My Computer, but I can't. :(
Can you help me to open it, because I have important information on it.

I am sure that you found a way to open your flash memory but I have an answer for whom it has a similar problem.
This problem is related to the FAT(file allocation table) which got corrupted when you had pulled the flash memory out without ejecting it first. So, to recover your data, Try to check disk the flash memory if failed, use a recovery software like "Recover my files" which scans the all flash memory not only the FAT.
Thank you

A few words of thanks would be greatly appreciated. Add comment

I have a bad news for you.. perhaps while exchanging information from one computer to another you have not disable your usb device properly and this has cause some conflict with you Usb flash stick.

Try formatting the flash disk and try saving information again and also make sure to disconnect the usb from windows before removing it from port to avoid any physical damage.


Thanks for the answer!
I'll format my flash and upload the information again. And I will eject it. :)
i huv same scenario. but hows the files? do I retrieve the files in my usb? I huv no back up. pls. help
What you do is if you wanna get your info off it, when it askes you to find the program, go to browse, then go to the WINDOWS folder, then press "e" until it highlights the explorer.exe program. Select it. You have to do that EVERYTIME though, until you format your flash drive. That problem also happens if you use your flash drive with Linux too much, then try to use it with windows... Good luck !

hello friend,

Just do one thing go to My computer>right click>manage>disk management

select the pen drive there separately and format...... check it again

if it doesnt works then again go to same location select your pen drive and opt for delete logical drive

then again right click to form a new partition or logical drive..... select form a new logical drive and again format it completely..

Note: dont opt for quick format,,, let it format completely.

hope this solves your USB Flash Stick problem,....."

The USB flash drive has been corrupted, therefore you can no longer open any of the files on the drive..... I know... it's happened to me before.

To be able to use the USB drive again, you have to format it. This will permanently erase the files but there is no other way.
