    I have 2 hard drives on the primary IDE chanel, a dvd-rom as master and a cd-rw as slave on the other chanel.

    The master device on the secondry chanel is stuck in PIO mode so when i go to use it, copy files to/from it it max's out the cpu - which isnt fun. The other 3 devices all use UDMA and they are fine when using them - nomial cpu usage.

    It was the cd-rw that was as master but i switched it to the dvd-rom because i use it less.

    Im running XP pro on an abit kg7-raid motherboard

    Anyone know whats wrong and what i can to to fix it ?

    Just checked mine - both IDE channels running in UltraDMA mode (if I hadn't checked I would have been sure the channel with DVD &CDRW drive was in PIO mode)

    Try firmware upgrade as BazH has said.

    Also try:
    In Device Manager
    (right click My Computer-->Properties-->Hardware tab-->Device Manager)
    IDE ATA ATAPI controllers
    Secondary IDE Channel
    Advanced Settings tab
    Change "Transfer Mode" on both devices to "DMA if available"
    Reboot.
    Go back in for a look to see if "Current Transfer Mode" has changed to DMA

    Obviously check in the bios as well (but I'm guessing you've tried that)
