you don't have to remove the partition. i'm guessing you dont have any games on the drive? if so back them up to PC first so you won't lose them. then format using the utility i posted before, the ps3 will see the FAT32 partition and the newest Multiman can see the NTFS side. you just can't put games on the NTFS section. My external HDD has 2 partitions on it, one for my Wii games and the other for my PS3 stuff.
