I really appreciate the effort you and others have put into helping me
with this problem. Unfortunately, I won't be able do things like
compile a 2.5 kernel or re-boot with ide0=ata66, until I return from
work in about 5 days time. I don't want to do stuff like that remotely.

Yep, tried that too but each time I see errors in syslog and

IIRC, this tends to happen when DMA is not fully supported for the
drive

Actually, some more digging shows some new support in the 2.5 kernel for
the VIA VT8235 chipset which is on my mobo. It seems that udma6 can
then be enabled by passing 'ide0=ata66' to the kernel at boot time.
(Note that I do have the drive connected using an 80 pin ATA133 cable).
Hmmm, I don't th
I have an just checked the hdparm output on another computer for an
earlier model Western Digital drive which is ATA100, 7200RPM, 40GB.
Therefore this drive should not perform as well. Here is what I get:
Note that the kernel being used on this machine also has compiled support
for using DMA by d

What does hdparm -i /dev/hda say?

Sorry for starting a new thread, but I was getting lost in the other
about hdparm since it started out as about KDE.
