1. click start>>run>>type in "cmd"
2. type the location of your flash drive.. e.g. "d:", "e:", "f:", etc..
3. type "dir /ah"
*you will now see the files/folders with hidden attributes
4. type "attrib [name of file/folder] -r -a -s -h"
*if you're going to unhide files, you should type the whole name plus the extension (format).. example "attrib party.jpg -r -a -s -h"
**if you have folders with 6 characters and above, type the first 6 characters then "~1".. example for folder named "birthday"
"attrib birthd~1 -r -a -s -h"
5. you should repeatedly type dir /ah after unhiding some files/folders so you'll know if they're now working or not..
6. now check you flash drive.. it should be there..

All the files with the extension .chk are files that are created after the computer was turned off using the power button and not the normal Windows closure proceedure.

All the .chk files can be deleted. If you delete them you may regain the space.

Dear Warrior,

I'm afraid to say that your pendrive has been seriously damaged (physically).
