I am using Vista Ulimate 32bit on a fresh install and I have
exactly the same problem as you with your drives, in device manager it only
shows 1 drive, if I scan for hardware changes the other drive reappears
but,then on a reboot it is gone again. I am useing a Pioneer DVR 112 WRITER
and a SONY DVD ROM. I have tried a combination of other older DVD Drives
but, still get the same problem. So I have proved it is not the drives
themselves that are at fault. Has anybody got an answer to this problem?.
Drives are set as Master and Slave.
