2 CDRs on Secondary Channel [24x Lite-on - Primary Master]
2nd CDR as Slave on Secondary [24x Lite-on - Primary Slave]

In the Bios it is enabled, Under win2k.. it shows as DMA the other is PIO.. Maybe this is somewhat related to the first problem slowdowns.. what can I do to improve the CDR writers... it used to take 4-6 mins to write a CD now but now... it takes over 20 mins.... Please help. As I have to backup many 3D animation files each day to CDR for design portfolios. I am using Windows 2000, SP2 and all the other patches. Please help. I installed the VIA 4 in one but still no help to it. It was quite fast before. I am using Nero 5. When I first installed the CDR Drive [the first one as being Secondary Master it was fast] Not sure why it got slow...when put the second one in.... the BIOS shows the secondary as being Auto... and under Win2k it shows DMA Mode...no Ultra DMA settings or anything else.

You might want to try putting one CDR on your primary IDE channel (IDE0) and the other on your seocndary IDE channel (IDE1).
What I mean is to put them on separate cables.

So if you have 2 IDE ports... put one on each. If you have to share one with your harddrive.. then do that but make it a slave.

This might help. I've never done something like this before but in this way each drive would have it's own channel to get data. In your current case the 2 drives are sharing a channel for data... that's where the slowdown might be.

I wonder if harddrive speed might also play a role in this... scsi harddrives are good for having multiple devices read to and from them!

Hope this helps.

Yah, burning from drive-to-drive on the same IDE is not a good thing. It overloads the IDE bus and you either get errors or very slow burn times. Mer posted good advice on a fix. Changing from DMA or PIO in attempts to increase the speed will only compound your problems.

Are you burning 2 CD at the same time? If so thats normal. I tried and it took way longer because it has to sync with each other. Also if you put CD writer together with harddrive it will slow down the hard drive to CD writer speed. Which is ATA 33 compared to ATA 66 or 100.

Make sure you're using 24x-Certified Media (ie FujiFilm and such).
the Lite-On has SMART-Burn technology that slows the write speed automatically if that media isn't made for 24x/etc.
