normla hard-drive on the ps2

[StartingLine]

i heard that with dms 3 is possible to format a common drive of 60g and used it on the ps2 with your backups
suck as resident evil
if this is possible?
what do i need only the dms3 and the lastest firmware?
or do i need other stuff to format the drive..
and what is the largest drive the ps2 can support?

thnx!
