| |
I'm using some maxtor on the same motherboard and I had to struggle a bit before getting some decent perf, basically I kept only the minimum IDE,ATA.. drivers in my kernel, for my P4PE it's the Intel PIIXn and also the PIIXn tuning option. I also added idebus=66 in my command-line kernel option... I disabled the Promise Raid controller in the bios that was responsible for some 2.4.20 kernels to hang at detection (?)
now I get this :
# hdparm -tT /dev/hda
/dev/hda: Timing buffer-cache reads: 128 MB in 0.30 seconds =426.67 MB/sec Timing buffered disk reads: 64 MB in 1.38 seconds = 46.38 MB/sec
# hdparm -I /dev/hda
/dev/hda:

this disk seems equivalent to your western digital.

a lot of device don't appear here because I disabled them whilst looking for what is causing my maching to hang once every three days...
