If i recall right, PIO mode goes 13.3 MB/second... wich is really slow, im not sure wich DMA mode they use, but UltraDMA 100 goes... 100.0MB/second
I would stick with DMA :)

My Plextor 12/10/32A will not use DMA Either, I have the jumper on the back enabled so it should be able to use DMA mode 2...

Also recently, when I burn a CD my PC really performs erratically, even the mouse cursor jerks!

I think it's time to format (I have had this installation on since October).

Do you have burnproof enabled? If you do, when your buffer drops, sometimes it will lag even my computer. (look at my sig) thats usually a normal thing

couple options

you might be able to turn on DMA in your BIOS

or you might need a new cable for your CD-ROM

or sometimes, just changing it from the master IDE channel to the secondary works (even though there's no good reason that would ever work)

maz4ruth,
I also have a 12/10/32a which won't go into DMA mode. I just figured it was because its "old". I didn't realize it has a jumper on it to enable this though (???). I'll look into this though. I do have mine on its own channel set to master.

Yeah GraveLayer, the jumper is to the left of the digital audio out, shorten this and DMA should be enabled...

The thing is, my BIOS recognises it as being enabled, but WinXP won't let me! :confused:

When I use my my burner, (it's the only drive on it's own channel...) whether for writing or reading, performance is bad.

I think a format and reinstall is the order of the day ;)

BTW... I think my problem could also involve VIA's 4 in 1 driver, I'll look into it.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there https://tinyurl.com/ycpxl
