I hadn't seen any replies to this yet, so I'll venture an observation of my own: CDRW should be the master device on any IDE chain that they are attached to, at least whenever possible. I've noticed marked reliability concerns and performance concerns when the CDRW wasn't the primary on it's chain, so I would switch the two drives around. That said, I hadn't noticed a problem with CDRW write speeds before in my setup (I have a Samsung 24-10-40 CDRW and a Liteon 16/52x DVD drive in my box, plus a 52X HiVal CD drive that I had had in the box until this past weekend, when I needed it's power connector to start my new RAID 0 array). Some media, however, are not able to burn well at higher speeds (I still have media my drive will default to 8x for, although other media I can burn on at the full 24x; the drive (and most of the better modern CDRWs) can detect the maximum media speed relatively well). I have yet to see 52x media, so you've got something there (I've only seen media rated at 24x, though the best media I've found is actually only rated for 8x (It was a CompUSA 100 pack I picked up for $5 after rebate) that burns at whatever speed I can dish out on any of the four burners I've got in my house, and the burner in a friends machine, 2x24, 1x12 (Laptop), 1x?
