Hello, I haven't visited in awhile (thankfully I've been busy working). Finally got around to buying an External HDD, picked up a Western Digital Elements 1TB drive. Yesterday I hooked it up to the laptop running Vista Premium and backed it up no problem. Today I tried a backup of our Desktop running Vista Ultimate and it told me I couldn't because the HDD is formatted in FAT32 (which apparently it is). Before I attempt to formatt the HDD to NTFS... is there infact a difference between Premium and Ultimate in reguard to backups? Or a simple way around this? Thanks.
