ok i moved the cd-rom from the secondary slave to the primary slave. i only increased a minor increase by about 2-3x. its on PIO mode 4 and will not go to DMA mode in windows or in bios. is there ant way to make it multi-word dma or anything? i really wanna burn on the fly w/o buying a new cd/dvd rom. thank you

Sometimes you have to uninstall the drive or/and the IDE channel before succeeding in enabling DMA . I had some issues like this with some drives in some cases .

By default the drive supports PIO Mode 4 (check the BIOS when it boots). If I remember correctly, there is a jumper on the back of the drive that when enabled, will make it UDMA 2.

Of course, you're not really going to see that much of a performance boost by doing that.

Have you tried other discs? Are you using a Mode 1 data CD? If its a CD-R, is the disc finalized/closed?

I saw the mention of the jumper either on this site or somewhere else; but for some reason never bothered to check, even when changing ide channels.

Probably due to when i email Creative and they told me it does not support UMDA. Stupid support.

Anyways, to the point, it worked and its performing on par, although i encountered different errors at one time or another when running, probably cause of cds.

Thank you I'm very grateful you opened my eyes to my lazyness lol

Thanks again!
