This probably couldnt be the problem, but I have faced the similar problem on my XP machine, while transferring files ranging in 600MB+ from CD to HD. The transfer would be complete, and when I remove the CD, it showed the file size 0. I just assumed that the same problem existed with you also.
Sorry for wrong info..
