I've got this really annoying problem! Have a portable HD that i used on my windows PC. There are rushes (moviefiles avi) on there that i really need. But it was NTFS so i couldn't put anything on it with my mac. I decided to copy my portableHD's content on to my MAC-HD. this worked out fine. Then I formatted the portable HD to FAT so that I'd be abe to acces it on my PC and my Mac. When i want to copy the files back to my portable HD it says "unexpected error, errorcode 0" Can anybody help me?
