I having a problem with my Flash drive. It is an LG 2.0 256MB flash drive. I noticed that it is no longer possible to write or read to it. I receive the message " the disk is not formatted". If I try to format it using windows XP ,98 ..., I does'nt format."cannot format the disk". Please can someone help me out. This is happening to me a second time, as i have already lost one of a different make the same way.
