As my drive is a brand new Seagate barracuda ST3160023A. The kernel reports
hda: 312581808 sectors (160042 MB) w/8192KiB Cache, CHS=19457/255/63, UDMA(100)
According to seagate [1], this drive has a max transfert rate of
100MB/s. So I think there's a problem with the kernels (both 2.4.25
and 2.6.3) that can't run run UDMA-4/5 on NForce2-boards.
I've already looged a bug to debian [2].
