Specs: Windows XP SP2
I'm using a Lexar 4GB jump drive and suddenly I have no files and I have no space. I don't want to format it because I have important documents on there. Is there anything I can do in Windows or Ubuntu to recover my files?

Have you looked at the drive in Disk Management? How is the drive identified and what is the partition type in there?

Recovering files is the most common problem we deal with here. I don't understand why people don't backup important files. Flash drives are the least dependable of all the different media. No matter where you store your files you should ALWAYS maintain at least two copies of any files you want to keep. S**t happens, as you now know.

The flash drive (or external drive, or memory card reader) must be plugged into a port it will actually work in.
See response 1

How to tell if the flash drive is properly recognized as a hardware device, even if you can't access it's data.
Programs you can try to recover your data, if that's okay.
See Response 2

The most frequent reason people can no longer access the data on a USB flash drive, USB External drive, or a memory card, is they unplugged it while Windows was running WITHOUT clicking on the Safely Remove Hardware icon in their taskbar lower right, and choosing to STOP accessing the drive.
(If you get a message you can't do that, then stop accessing it elsewhere - e.g. in My Computer or Windows Explorer, or in whatever you were accessing it with, e.g. change the drive letter, then you will be able to STOP it in Safely Remove Hardware.)
The Safely Remove Hardware icon may be hidden - if so, you have to click on < at the left end of the icons in the taskbar to reveal it.
It's a gray rectangle with a green arrow on it in XP, 2000, and ME, (and in 98 and 98SE, only if you have third party flash drive etc. drivers installed, or you have connected an external drive.)
In Vista, and probably Windows 7, it's a medium green small circle with a white checkmark on it.

If there is no Safely Remove Hardware icon, then there's something not right with the software that is supposed to make the icon appear (e.g.that sometimes happens in 98 and 98SE) - you could try rebooting, but if the icon still does not appear, then DO NOT unplug the device while Windows / the computer is running.

You can unplug the device at any time when Windows / the computer is NOT running. You can plug it in at any time.

@Othehill: I can't look at it in drive management. It shows up under "My Computer" as a FAT32, but when I try to do anything with it ("cd" from the cmd prompt, for instance) it ejects itself and is no longer visible to my computer.

I have, however, plugged the same jumpdrive into an Ubuntu computer. The files are all still there! But after trying to copy them over, the drive disappears.

You can't see the drive in DISK management?

What file system is on the drive?

Like I said...


It doesn't show up in Disk Management.

And the file system, or as much as I can tell, is FAT32.

See and heed the info in response 2, and try one of the data recovery programs.

If that program can't find the drive, or if other indicators do not show the drive is at least detected properly as a hardware device in Device Manager, throw it away - there's no way you can do anything with it - it's toast.

If the drive doesn't show in disk management at all then I think it is a USB issue.

Have you tried all available USB ports?

Do all USB ports work with other devices?
