OS is XP. Deleted both CD-ROMs from Device Manager and restarted. Put DVD in top drive (F?) and it recognizes it. Put DVD in bottom drive (G?) and it does not recognize it, although “G” shows up on the list of drives. It asks me to place a disk in drive “G”. So, I put it in the top drive (F?) and it recognized it. So, is the computer seeing the primary top RW drive as both “F” and “G”. Pulling hair out.
If you have another IDE slot on your motherboard for harddrives, try getting another ribbon cable and plugging the end plug into your second drive. You can try a different ribbon cable and see if that works, but if you swap the drives (set up the Master as slave and slave as master) and you get the same result, then it is your bios program.
I think your motherboard is seeing the DVD drive, but you are not passing data.
That, and it is windows...so it normally never works with anything, anyway!!
I went Mac and will never go back, precisely for this reason!
