The system is XP SP2, some time ago bought a new mobile hard disk 160G, 2 hours PQmagic8.0 the 80G partition, and then from my computer a copy of about 50G things back up to a mobile hard drive On the district.As a result, today received another mobile computer, mobile hard disk to back up the release 50G of the document shows that the district had only 127M, with the key thing is that I set it back up the file could not find the one.Is the quality of mobile hard disk problems? XP SP2 or greater than 32G into the district in question?

bad by the way, fat32 no more than 32G, because dos can only be managed under the 32G, if not In order to facilitate the management dos no need to use fat32, so if more than 32G with ntfs, or you do not know how to use dos disk management, use ntfs.
PQmagic Personally, I feel nothing good, hard disk on the big points a lot of little , You like their size so that changing it? Well on the problem.
