IDE, not SATA, right? Just so we have the terms straight,
let me explain:
IDE = 40/80 pin ribbon cable, connects motherboard to disk
and CD/DVD drives
SATA = 4 pin twisted serial cable. Connects motherboard to
disk and
CD/DVD drives
ATA = Command language spoken by _hard_drives_ that are
connected via
IDE or SATA
ATAPI = Command language, similar to SCSI, that is spoken by
CD/DVD
drives over IDE and SATA
There is no such a thing as an ATA DVD drive, but there are
ATAPI DVD
drives. The interesting question is whether yours is IDE or
SATA.
