I just got a new Hitachi 80 gb hard drive to add on to my current hard drive.
amd athlon 64 3400+
1 gig ram
350w power sup
My current hard drive is a samsung SATA RAID 120 gb. I also have an NEC dvd rom/burner. The burner and the new Hitachi hd are both ATA100 where the old/current hd is SATA.
So here's the problem: I installed the Hitachi, and then for some reason, my burner stopped working. It acted as if it was receiving no power. I set the HD to master and the burner to slave, still no work. I unplugged the hitachi from the mobo but left it plugged into the power supply, and the burner worked fine, so i don't think its a power problem, but i can't be positive.
