smj1860 said: all you have to do is change the settings on the external drive and then plug it in your USB port on ps3 go to the backup restore under settings on the system and it will back up your file.....I think the settings you have to change on the external drive is the file name i think it has to be an exFAT file |
exFAT won't work outside of a patched XP, vista or Win7 PC.
NTFS won't cut the mustard either.
the external drive will need to be formatted in FAT32.
You'll need to prep/format it with a third party formatting/partitioning tool (or Linux), because Windows won't allow you to format a drive that size in anything but NTFS or exFAT 
also your new PS3 drive will need to be a SATA laptop size HDD, if you didn't know that already
