I tried to access important document files on my flash drive and a message that it isn't formatted comes up. I tried scanning the drive, but can't scan it because the message that it is not formatted again comes up. I tried to copy what was on the drive, but nothing is copying no matter what I try. Yesterday, there was barely any space used, but today the properties show that ALL of the space on the 1G drive is used. I don't know how to get the files off. Is there anything I can do? Thanks for your help.
