    hi

    almost the same happened to me with Promise RAID card and couple of IDE WDs
    (100..120GB).
    finally I found that the source of these problems was noise-reduction feature
    that is turned on on some IDE disks which were probably designed for
    desktops. so I upgraded firmware on all WDs to turn it off - and voila - it
    works just fine !

    details here:

    hope this helps
