[Soekris] net4801: no UDMA?

[Richard Homonnai]

Hello,

I am using my net4801-60 now for over a year successfully.

Today I exchanged my old IBM Travelstar 10GB Disk into a shining new 60 GB 
Hitachi Travelstar.

It is a way faster but, it just uses mdma, no udma.

So I inputted hdparm -X udma2 /dev/hda.
However, with
hdparm -tT /dev/hda
I got some bad results in my log, and it was slower also.

I went back to mdma2 after that.

So my question is: have I done anything wrong? Or is it normal like this? Is 
udma2 bad?

Technical information:
[   14.794252] hda: HITACHI_DK23FA-60, ATA DISK drive
[   14.824518] hdb: TRANSCEND, CFA DISK drive

hdb is running without DMA, as needed.

Kernel is: 2.6.18-gentoo-r4-richGATE running on Gentoo.

I hope someone can help me.

Greetings,
