    Thats low. I get 25.5 MB/sec from my old Maxtor 96147U8 on a P2L97-DS
    (this was Maxtors first 60 gig drive - 8 heads, 15 gig per platter -
    yours has 3 heads with 40 gigs per platter. the higher recording density
    should make it even faster than mine).

    But: This is still more than my IBM DTLA does on that board - which in
    itself is perfectly capable of 36 MB/sec when driven with UDMA 100, but
    drops to approx. 22 MB/sec when limited to UDMA33. So your drive might
    have a similar issue. Its nominal transfer rate is higher than UDMA 33
    can deliver, and it wastes bandwidth in adapting to the slower bus.
