Re: Flash Drive
goto the my computer on your machine whent he drive is inserted, and right click on the drive and select properties. Goto the tools tab, and select error checking. when the dialog box comes up and asks you to automatically fix errors, check that box, and also check the other box to scan for and attempt recovery of bad sectors and click ok.
This will run a checkdisk on your thumb drive and attempt to recover the lost files and bad sectors. A lot of times, if you just boot your computer up with the drive in, the checkdisk command will run automatically.
