achelmer,
My guess is that he's outta here as I would have been even earlier as it took 4 posts to get this out of you.
"ok, I have a 20 gig as a primary master, and a DVD on Primary slave. A 30 gig on Secondary slave, and an 8x burner on secondary slave. The 40 gig is on my Primary master on the Promise UDMA 100 contoler."
Sounds to me like you have one of your drives jumpered incorrectly, but I can only guess as I'm not there to see your rig.
Why not try running your 20GB as Primary master on your ATA 100 and your 40GB as Secondary Master on your ATA 100. (or vice versa as you didn't say which drive had your OS on it?????)
And run your DVD and burner on your ATA 66 controller, as you won't use the ATA 100 on either of those devices anyway.
By the way..next time you post a problem, try to give as MUCH info as possible if you're intent on getting help.
Either that or sell your 'puter and get a sony play station.
