OK well I just tried adding some atacontrol commands to /etc/rc.local to force them all to 100 and it appeared to execute them upon boot. In various tests this evening I was getting errors even when trying to mount a drive while another one was on the same channel. However the atacontrol to rc.local seemed to do the trick for now, and I hope it continues to work....unless there is a better way to do that for all my drives upon boot. I'm not too worried about any 133 performance increase at this point. I just want the stuff to work. Here is how I had planned my configuration to be: Primary IDE Master - Maxtor 200GB (FreeBSD) Secondary IDE Master - TDK VeloCD Burner Secondary IDE Slave - Sony DRU500A RAID 0 Master - Maxtor 200GB (Storage) RAID 0 Slave - Maxtor 160GB (Storage) RAID 1 Master - Maxtor 80GB (Storage) RAID 1 Slave - Maxtor 80GB (Storage) I do have a tall Antec case, and have both 200's and the 160 in 5 1/4 inch trays so the cables for those are long (36 inches IIRC). Would it be OK to have that setup, or would it be better to isolate them all on their own cables/channels and get a Promise card or something for the other two? I'm not going to be doing huge file copying a whole lot, but I'd like the most performance I can get with no errors. Thanks for the replies. -Mark
