I just bought a WD 40G 7200 which I want to make my primary HD. Currrently I have a 4.5 G IBM scsi II HD (about 90% full) which I want to make a secondary drive. I set the jumpers on the WD to be primary, connected the ide cable to the primary ide slot on the mobo (Tekram P6Pro A+). I downloaded Data Lifeguard Tools 2.60 and tried to install. I got the drive formatted and partitioned, but could get no further. System does not recognize the drive. I tried changing in CMOS the boot from scsi to primary ide, but no luck. CMOS is set to auto for primary and secondary drives. I'm a little new at this. Can scsi and ide hard drives co-exist? Any ideas? Thanks.
