Drive shows up as PIO mode only

I'm trying to find out what could be going wrong with my drive setup. I just
put together another computer from various parts, all of which worked OK
before.
But the 30 GB drive on the secondary master will only list as PIO mode in
the device manager.
I used a QDI mainboard that had previously handled 40 and 60 GB drives in
ultra dma modes.
I have a 20 GB C drive and a CD drive on the primary controller and both
show up as dma drives (ultra dma mode 5 and multi-word dma mode 2)and have
only the 30 GB drive as the master on the secondary controller, which I want
to use for video, but if it only shows up as a PIO mode drive, I know it
won't be able to handle it.
It's a windows XP home with SP1 setup and I have not yet installed any
software (just built it today) until I get the drive problem worked out.
The drive is the only component that I haven't used before since it came
from the IT department at my school, but it's a 30 GB maxtor and it's
unlikely that any 30 GB drive could be so ancient that it wasn't dma.
The motherboard has a VIA chipset and I installed the latest Hyperion
drivers just in case that it was the culprit, but that made no difference,
and anyway, the other drives on the primary controller were being recognized
as ultra dma already.
The cable is an 80 pin ultra dma cable.
I just can't figure out what could be causing it to see the drive as PIO
mode only.
I've built many computers before, so I'm not new at this. I tried changing
some options in the bios but nothing has made any difference.
I have a little 6 GB drive at home that I will bring in to try on the
controller on Monday just to check if it's the 30 GB drive at fault, but I
would appreciate it if anyone can please give me some advice or suggestions
to try.
Thanks a lot.

I have no good advice, but for an interesting experiment, you could try the
30 GB drive as a slave off the 20 GB C drive (in place of the CD drive), and
see how it shows up. If it still shows as PIO, I would guess the drive is
at fault.

I think by default, Win XP will set the Primary's slave as PIO only.
You can change this setting by going to :-

Device Manager > IDE ATA/ATAPI Controller > Primary IDE Channel >
Advance Settings (tab)

Change them to "DMA if available".
