If Disk is corrupted, try to reformat. Before reformatting, try to backup all your data using this recovery program Recuva - it is free http://www.piriform.com/recuva
Bad sectors on the flash drive forsure. Perhaps you pulled it out when it was not ready, this usually screws *** up on a fat32 formatted Flash Drive. Do as jsmakkar said, and if needed use the recovery program he linked too.
