    Using Windows Server 2003 R2 SP2, I am still having a problem with an IDE
    controller only operating in PIO mode instead of DMA (which slows my system
    to a crawl). This problem was described in KB81742 and KB919168, and was
    supposed to be resolved by SP2. It is also described here:
    http://winhlp.com/?q=node/10 None of the proposed solutions seems to work for
    me. If I delete the MasterIdDataChecksum key (see
    http://winhlp.com/?q=node/10), it works temporarily, but then reverts to PIO.
    Can anyone tell me what to do to solve this?

    Thanks!

    Hi,

    I've had this problem before and i found that changing the ATA controller
    driver from device manager has resolved it, If you right click your ATA
    controller in device manager and select update drivers then select advanced
    and don't search i will choose a driver to use. Normally there will be a
    couple in the list if you try a different one the one currently in use and
    see if that works..
    There is a chance this could stop your server booting but if that does
    happen normally choosing 'Last known good configuration' from the boot menu
    should put it back :) You may wanna take an image just incase.

    Regards
