USB Flash Drive Problems

[NotesPack]

Hi everyone!

I have a 2GB USB flash drive. It is a new one and for the last two days it worked perfectly. But today I experienced some problems with it. When I inserted it in the USB port, the flash drive was recognized by the OS, but when I clicked on Removable Disk (F:) in Windows Explorer, I saw nothing! The drive was with some files just yesterday, but now, there is nothing! I viewed the drive properties, and I was sincerelly shocked: there is 0 bytes free from total 0 bytes. I ejected the drive, and inserted it again. Now, I saw already my folders, but unfortunatelly, when I clicked one of them, it was empty, so the problem was the same when I viewed the drive properties (0 bytes free from total 0 bytes). After some time, I inserted the drive again, and it worked good for a time (I even tried to copy my folders to the hard disk), but while it was copying (there were ~50% completed), the drive disappeared again, so the process was interrupted.

I tried this drive on other machines, and there it works good, without any problems.

What is the problem?

Any help is really appreciated (however, I should mention that I don't want to format the drive because there is some serious data stored).

Thanks!

Take a backup asap. Then go for furter testings with your drive on other computers and with other drives on your computer. I suppose you've tested it on more than one usb plug from your computer ?

I tested the drive on several machines. And I did even more - I tested the flash drive on the same machine, but with other OS (it is Ubuntu 5.04 Hoary Hedgehog Live CD). It worked in the other OS very good. But when I return to Windows, the same problem appears again. So, as I see the problem isn't the flash drive. May be there is some bad software installed, but the other flash drives are working good on my machine.

Any ideas?

Thanks!
