My flash drive has always performed as expected in numerous PCs that I have used it on. Starting yesterday I have been experiencing a problem on every PC I have tried it on (all Win XP). When I insert the USB drive, the drive shows up in Windows Explorer with the appropriate volume label and all files are visible. After about 30 seconds the volume label changes to "Removable Disk (E:)" and the files are no longer accessible. After the change, the properties tab shows zero files/zero disk space used. I can remove and re-insert and the process starts all over again. I disabled auto-play with the same outcome. Can anyone help me to assess whether or not I have a virus?
Thank you,
