I've not had this problem, but my initial question is whether you are
probably unmounting the drive under linux. (Right click, choose
unmount, I think.) The reason is that writes to USB-connected flash
drives are buffered in Linux. The file will appear to copy, but
actually was only written to a memory buffer and not written to the
actual drive until some seconds/minute or two later. When you unmount
the drive, that memory buffer is cleared and actually written to the
disk. Make sense?
