I am having trouble with a Gateway 256mb flash/thumb drive. I can open the drive and open the files within, but I am unable to delete them. A friend used it aand may have pulled it from the USb port before everything closed. I have tried to re-format the drive, rename the files, move the files. Can anyone think or help me with any other suggestions. I can care less about the files but would like to use the drive again. Anything is appreciated.
