HDD stuck on UDMA2...

[Metaxas]

Ok, my drive (Maxtor ATA133 40Gig HDD) is "stuck" on UDMA2 and it WILL NOT go any higher, it will go lower...(ugh) but nothing available over mode 2.

Open terminal.

su - root
**************

hdparm /dev/hda - to see what's up
hdparm -i /dev/hda - to see more of what's up

First I did this:
hdparm -c3 /dev/hda - it took it, and no problems. (Was on 16-bit...ugh.)
hdparm -d1 - that was already flagged, so no probs there.
hdparm -X68 /dev/hda - says its changing it...it doesn't.
hdparm -X67 /dev/hda - says its changing it...it doesn't.
hdparm -X65 /dev/hda - says its changing it...it DOES.
hdparm -X64 /dev/hda - says its changing it...it DOES.

Also tried a variation:
hdparm -Xudma5 /dev/hda - says its changing it...it doesn't.
And so on, and so fourth.

My bios (Asus A7N8X Delux) is setup properly.
My drive itself is setup properly.

Copy and past of hdparm /dev/hda:
/dev/hda:
multcount = 16 (on)
IO_support = 3 (32-bit w/sync)
unmaskirq = 0 (off)
using_dma = 1 (on)

readahead = 8 (on)
