DMA Mode

Discussion in 'Windows XP' started by Rhino, May 26, 2010.

    I'm using Windows with XP SP2 on a nearly new computer (18 months old).

    My CD/DVD burning software is Nero OEM 6.3.1.26. (InCD is 4.2.12.1.)
    Whenever I attempt to burn a new CD or DVD, I get a message from Nero DMA
    Manager saying "This application has detected that your drive is not in DMA
    (direct memory access) mode. To improve your system performance we suggest
    you to enable DMA for all drives. Do you wish to run Nero DMA Manager to
    enable DMA mode right now?"

    I have clicked OK and rebooted (after it was done) on several occasions but
    I keep getting this message. I've checked Device Manager and found that both
    Primary IDE Channels and both Secondary IDE Channels indicate a Transfer
    Mode of "DMA if available" for both devices in their Advanced Settings.

    1. It looks as if the settings are correct so why am I still getting the
    message?
    2. Is it possible that I am actually using DMA despite the message? How
    could I be sure?
    3. Is it possible that a CD/DVD burner manufactured within the last couple
    of years would _not_ support DMA? I thought that only very old drives didn't
    necessarily handle DMA. What would I need to know about the device to
    determine if it supports DMA? The burner is a Lite-on DH-20A4H 20x DVDRW.

    I'd like to get the DMA mode working if it isn't, assuming that it will
    actually speed up the burning process. If it doesn't speed up burning or
    have some other major benefit, then I can live with it the way it is ;-)

    Suggestions?

    Remove the CD driver(s) and reboot. This is the usual method of fixing
    your problem.

    Windows XP changes the mode to PIO rather than DMA if there ever is an error
    on the drive whether it is currently recording errors or not.

    Many devices require a jumper to be set in order to utilize DMA ... check
    the manufacturer's data sheet for the device.

    Thank you all for the suggestions! I'll get back to you if they don't pan
    out but I'm optimistic that one of these will solve the problem.
