You want to install windows on new clear SATA drive?
if yes, do next
unplug all yours drives, except new SATA drive( on this drive you will install windows).
don't forget remove jumper that limit speed of hard drive to 1,5gb (without this jumper SATA drive have speed 3gb)
it placed on back side of disk.
when you start install Windows you will have possibility to format and split new disk on several partitions
do not make system partition so big (180 gb) 30-40 gb for C it's the best variant I think, but it's up to you of cause
SATA and ATA disk almost equally if you not run SATA drive in RAID mode.
when you will install windows on new SATA drive, plug old ATA drives. and use all of yours files
may be my advice no for this event. but it's (unplug old drive with information before installing windows on new one) help you save all of yours precious data
Good luck!
