I have a problem with my 2GB USB flash drive. It all started when I saved some documents in an internet cafe. But when I plugged it in to another computer or device, it was not recognized. Furthermore, the indicator light no longer lights up.
Does it only happen on a single system? If so, perhaps it's a faulty driver. If you can still access the flash drive, there are several tools on the web to help repair a flash drive.
I suggest simply getting in there, backing up your files to a stable drive and purchasing a new one.
Next time follow certain guidelines so that you don't corrupt your data. I suggest an article Tina *just* wrote http://www.makeuseof.com/tag/how-to-use-a-jump-drive-corrupting-data/
Download ubuntu: http://www.ubuntu.com (it is about 700mb)
burn it to a disc, restart computer with disk insade, boot from ubuntu, when you are in, say test ubuntu, then when you see a desktop, plug in your flashdrive, it will probably open your flash, create a folder on desktop, and say backup, then copy the contents to folder. then go to disk utill ( if your pc supports unity, then just search for it in the ubuntu menu, the circle icon in the top left screen, then choos your flash (it wil be under usb devices) and format it, and use the fat 32 file system.
After that, you can restore your backups on your desktop.
BTW, ubuntu is a operating system and but it is free... check it out :)
That should sort out your flash
