My question Dave, is how old is your motherboard? I guess it's a P35 with 2 IDE channels? I'm wondering why you're just not using all SATAII drives, I have 6 in my system, using the RAID config. I put one of my OLD (10 or so) IDE drives in the computer on the 1 IDE channel. But the damn drive was so loud, compared to the SATA drives, that I just ditched it altogether, and I'm all SATA (with 2 SSD's in RAID 0) as the system OS. I'm sure it worked at one point, also, check out how much of the drive is full, you may be now writing to the slower inside tracks (I read TONS about this crap) as I'm into buying 1TB drives, and short stroking them to only use 250 GB or so, which out perform faster 10 000 RPM drives!!!!! And it's the same price as regular 250 / 320 GB drives, with RETARDEDLY nice performance for the buck. They are bigger though!
