John, I have a collection of a half dozen 8+Gig files that I'm trying to transfer. One thing I tried was to break them up into 200M chunks and then transfer each chunk one at a time. The first chunk went fine but then it crapped out on the second one, as if the bad effect of the transfer was somehow cumulative.
