It's a complicated subject. 1) In a 'standard, off the shelf' PC you have a single hard drive and a single CDRW. In that case you make them both master devices on separate channels. No conflicts. 2) In my IDE based audio drive system my second drive is on a second controller so I have 4 channels available. In this case all the drives are still master devices. (See - not 'everyone sets up the HD on one channel!) ;-) In Robert's case he wants to use the two channels available to him. He knows he's going to use the two drives at the same time, so he's optimized for that usage. However, you are correct that if he was to mix an older CDRW/DVD drive that was (possibly) a UDMA1/2/3 drive, with his nice, new UDMA5/6/7/8 hard drives, then the system might have to slow the EIDE cable down and his drive would go slower. He'd still be spinning at 10K RPM, but on the cable he's be going 33MHz instead of 100MHz, etc... It's a crap shoot answering questions like this without madel numbers for all the devices, and if he gave me model numbers I'd probbably run and hide as figuring it out is too much work. ;-) - Mark
