Flash drives do eventually wear out, usually after a lot of use. I'd try to see if maybe it would work in another PC. If you ever get to the files, be sure to copy them to another device!
hi guys ! well i go right into the problem , my flash drive was named : omarison then when i plugged it to my computer i found that the name was converted to "removable disk (F:)" and all files disappeared ! but the properties still show that 153 out of 956 MB is occupied which makes me sure that my files are there ! but i cant look nor open them ! any solution ?
