I've been having this problem for quite awhile now. Some files, particularly psp isos, have this huge lag time before a transfer box pops up to show its progress when I'm transferring it from an ext hd to my laptop's hd. Also moving the isos within my harddrive have the same lag time (excluding the transfer box). I don't know if it's the isos or if it's my harddrive that is having the problem. Any ideas?
