    Hi

    When there is some sort of disk error in WindowsXP, the data transfer to the
    IDE disk is set back to PIO mode.
    The only way of doing a reset of this, is to remove Primary IDE controller
    from the device manager (The only metode I know)
    After the PnP has installed the IDE controller, the disk is back in UDMA
    mode.

    So, is there any other way of remove the use of PIO mode ??

    Is it possible, somewhere in registry, to tell WIndows not to switch to PIO
    mode on IDE problems ??

    If I recall correctly the registry is where this state information is
    lodged. Figure out what is getting set where and clobber it back to what
    it ought to be.

    On the other hand, what has gone wrong with your disk?
