Hi,

Usually DVD-rom is faster than DVD R/W.
My 3 years old Asus 16X DVD-rom has DMA mode 5 but my new Plextor 712A 12X
DVD R/W only has DMA mode 2 (it is by design as higher DMA mode may cause
burning problems)
Connect the faster drive to master and the slower drive to slave.
I use 80pin shielded cable for both drives.
If you are sure that both of your optical drives is DMA mode 2 by design,
you can just use 40 pin cable. (80 pin shielded cable is required for DMA
mode 3 and above)

Make sure you have enabled DMA mode in BIOS for the primary and secondary
IDE channels otherwise you cannot set it to DMA mode in device manager.
Also check the jumper setting of the drives, you cannot set to cable select
by using a 40 pin cable.
