The playstation 3 will only recognize an external hard drive that is formatted in FAT32 format. I have a 80 gig Seagate Free Agent Drive that came originally in NTFS format.
I'm using F 11 and formatted the drive to fat32 using
mkfs.vfat -F 32 /dev/sdb1
This formatted the drive to Fat32; however, the ps3 will still won't recognize the drive. I tried using fdisk to create just 1 partition in Fat32, but it is still not detected.
OK i finally got it working. Not sure which method worked though. What I did was use fdisk and created a new partition with 1 first cylinder 1024 last cylinder. Then I used the Gui interface and right clicked on the drive icon and had it formatted to FAT32.
