I can't talk about the specifics here, but I'd reccomend that you do not
use xcopy for anything big. It mostly works with fat32 systems, but
fails in strange ways when dealing with ntfs. So, in looking for a general
replacement I found xxcopy, which does seem to work no matter how
much data you move. My record is one xxcopy copying 610G of disk,
and it worked.
I don't know what your problem is, but I cast wary eyes at xcopy in
general these days.
