My flash drive is really problematic why is it that it has refused to format completely. i cannot save anything on it and when i try to it says this disk is not formatted. Can someone help me out here

Quite unfortunate that we hav many fake flash drives in market today.
well, i will profer a solution to u, but unfortunately it will only work if u can use DOS  (Disk Operating System) programe. if u can then-

1. Plug the flash drive properly into the USB port at the rear of ur CPU
2. Ensure the system detects the flash drive. (if it does not, right click on ur desktop, and click REFRESH) then check again if it has detected the flash drive, if it does not, then restart the pc. if it does not still, then throw the flash drive far into the bush
3. Click START>RUN> type CMD (Command) & click OK. (this opens DOS windows) its a black screen
4. On the DOS window, at C: prompt, type Format E: then strike the enter keyboard and brings up some notice for u to insert the drive u wish to format, just ignore it and strike ur enter key again.

it complets the formating process!

N/B drive E: here refers to the flash drive, if u hav drive C: & D: then automatically any additional drive like a flash drive becomes drive E:

this looks lil bit technical right?      
Cheers!

Throw it away and stop buying flashdrives by the roadside.
