I have this strange problem with my laptop. Whenever I try to copy a large file to any of my 3 external hard disks (1 Maxtor, 1 Hitachi and 1 Buffalo), the speeds are tremendous for most of the process at around 70MB/s. However, all file copying gets stuck just when the copying is about to finish. Like with around 40MB left, it will stay there for around 20 seconds before actually finishing. Can anyone figure out why?
