    OK now time for hopefully somebody to help me out here. I have a computer here that is making me about to pull my hair out. The DMA on the C drive will not stay checked under Device Manager - Type 47 - Properties - no matter how many times I reboot it goes back to being unchecked. I have looked around for info on this and the only thing I can find is from Microsoft about running a debug to see if the hard drive supports multiple word DMA protocol. (Microsoft's Q159560 if you wanna see it). It passes that fine. I have looked in BIOS to see if anything there could be causing it. The DVD rom and the CD-RW are both set to DMA moda and stay there just fine. The DVD is on the same cable the hard drive is on. Any suggestions all? Here is what the comp is made of.

    Custom Built
    AMD Athlon 550 mhz processor
    192 meg PC133 (running at 100 though) SDRAM
    ASUSteK K7M-RM motherboard
    Toshiba DVD Rom drive
    Sony Expressa 8X4X32 CDRW
    ZIP 250 Internal Drive
    20 Gig Maxtor Diamond Max VL20 Hard drive
    ATI Expert 128 16 mb video card
    Linksys 10/100 Network Card

    Hope somebody can help as this is gettin on my nerves. Thanks in advance!!!!

    Maybe DMA is not supported by your hard drive.
    You might contact the support dept of the manufacturer for more information.

    Good luck,

    Hi 4 Computer Fix,
    I have to agree with TonyKlein! If you check the box and reboot, then it is unchecked again, the Hard Drive does not support DMA.

    The debug script outlined in the Microsoft Q159560 article sees if the hard drive wil work with DMA - was first thing I tested. I knew it was and would run with DMA - actually I got it working with UDMA - downloaded VIA DMATool - just click on what you want running on DMA and reboot - too easy. But thanks for the help.
