I previously had an AOpen 24X and a Mitsumi 32X (16MB buffer) hooked up on two seperate IDE channels. My HD is hooked up to the RAID channel on my mobo. I was using Nero successfully to burn images (.nrg) to both recorders simultaneously. Of course, I was burning at 24X speed to try to keep them in sync. I'd finish both CD's in about 4-5 minutes.
Well, I just bought 2 40X Cenedynes (Verbatim drives) and hooked them up, hoping to see an increase in speed. For some reason, I can't finish a simultaneous burn w/ the matching recorders! It goes through the whole burn, and then crashes at the very end. One drive will power down, but the other's burn-light will stay on. The only way I can finish a burn is to use Track-at-once, instead of DAO. Using TAO slows the burning time down to the 24X speeds I was burning at before. I even tried to burn at slower speeds w/ my 40X's, but nothing
I was thinking about flashing the two drives to Lite-On's and seeing if anything changes.
edit I tried taking one 40X drive out and putting the 32X Mitsumi in, but it still won't finish
