My Flash Drive Won't Format

hello Friends, please I ran into this problem and now I've not known how to tackle it.. while I was working with my flash, it got to a stage where it won't eject safely.. so I had to pull it out from the pc.. now the flash won't format..neither quick nor full format... I even had to change OS, but still no change.. now am In windows 7 tryin to do a full format.. but it's takin ages and wouldn't even show a sign in the progress bar.. the funny thing is that on the "capacity field," it still shows the size of the flash (7.53GB) making me believe it's still good.. please is there anything I can do to fix this precious flash drive of mine.. thanks a lot in anticipation...
