Dual DVD Burners; Making them work?

[BobAndy]

Greetings folks 😀

I've got two IDE DVD burners hooked up, 4 SATA HDD's, 2 gigs of ram, a C2D 6400 Procy and a P5WDH board.

What I'd like to do is burn two DVDs at the same time; however, when I try to do this, the time goes from 7 minutes or so to a rediculous 33 for both, and at one point one inevitably fails. I was wondering if anyone had any ideas as to how I could make them both burn at the same time, without errors.

The drives are both in DMA, and the only thing I have not yet attempted is to put one of the DVD drives on the Jmicron controller and the other one on the 'Board' controller; I'm not sure if that would do anything though.

Any hints, suggestions or clues as to why this doesn't work as I'd like it do would be most appreciated.

are both drives the same?

Very similar; One is a Samsung Writemaster 18X w/ LScribe and the other is it's older cousin, the Samsung Writemaster 16X.

I should also specify that I'm trying to burn two DVDs containing DIFFERENT content, not the same 'dvd'.

Is one master and one slave on the same IDE channel or are both master on two different IDE channels?

I'm fairly sure one is a master and the other is a slave on the same channel... It's been a long time since I've installed them... and just as long between restarts 😛

There you problem. I believe they both need to be on their own channel. So both need to be master.

That's right, advice from the guy who posts more stupid questions than anyone else at AT.

He's right though. IIRC the slave must route all requests through the master. It would probably be a good idea to put them on different channels and make both masters.

And you didn't think that would cause a problem?

true. although burning a single DVD doesn't saturate the IDE bus, burning two does. put them on sperate channels and it will be faster and shouldn't fail either.

It will help to put them on seperate IDE channels or put one in an external enclosure, but even more importantly is whether you are using different source drives for each burner. If you try to burn two different DVDs at 8x and up from the same source drive, your burning program will be constantly slowing the burn down to refill the buffers.
