NEC 3520A and Pioneer DVR-109 DMA Modes?

[Poppa_Meth]

I finally have both my burners installed. I have the NEC as Master and the Pioneer as slave, both on Cable Select setup on the secondary IDE. My Pioneer runs in Ultra DMA Mode 4 and the NEC lists as Ultra DMA Mode 2. Is that normal or should they both be in Mode 4 since they are 16x burners?

don't use cable select, manual select master and slave using the jumpers.

There is nothing wrong with using cable select and you can leave it as it is. The device connected to the middle connector will be the master and the one on the end will be the slave if you are using a 40 pin cable, reversed if you are using an 80 pin cable. As far as the UDMA mode that is in use, the Pioneer is an ATA-66 drive and the NEC is an ATA-33, so nothing is wrong.

Thanks for the input. I just discovered that on the CDFreaks forums as well. Not many optical drives have UDMA4 interfaces yet.

The Pioneer 109 will not work in UDMA4 without an 80 wire cable.

Yeah I've got 80 wire cables. Dell actually did something right and put decent cables in this 3 year old machine. I was actually looking into new cables before I bought the burner due to this, until I realized what I had was fine.
