I just figured it out... Since I couldn't find any IDE updates, I installed a Promise ATA100 card I had and hooked up the 40125S to it. It finally worked, but when I tried to burn some files from my HDD (about 100 Mb), the 'burned portion' of the CD-R was right in the middle of the disc instead of starting from the center - WIERD. I installed the ZS0J (it had ZS0A originally) firmware update as a possible fix, and everything seems to be fine, except Nero Info Tool does not seem to want to work with the burner set up on the IDE card. Is there a way to disable SMART-BURN for the purposes of using Nero CD-Speed?? I can't get the drive to exceed 32x, since that's the highest rated media I have around. Thanks!!
