I have a Western Digital drive and it keeps freezing the transfer process around 15 seconds remaining. I am trying to transfer my movie files to it. The files are around 750 megs to 2.5 gigs each. I am trying to do them one at a time. I have got it to transfer about 3 movies to the device. When the transfer locks I have to turn off the computer and turn it back on to get it to stop. Its I think a 110 gig external.
