Slow disk access on Dell Latitute with ATA/ATAPI-5 T13 1321D
Hi...
I have a Dell Latitute with an ATA/ATAPI-5 T13 1321D and it would seem
that my disk access is extremely slow. I have the latest updated kernel
from RedHat 8.0 kernel 2.4.18-27.8.0. Somehow I think it is related to
the UDMA stuff (shows my level of understanding). I have run hdparm and
although I think I should at least udma level 5, I have at most udma2
listed. Is this a kernel option/update problem?
The first question is whether my disk is really not optimum.
Any help or help would be appreciated Or if you need more info just ask.

Here is some less vague info:
----------------------------------------------------------------
hdparm -i /dev/hda
/dev/hda:

UDMA modes: udma0 udma1 *udma2
AdvancedPM=yes: mode=0x80 (128) WriteCache=enabled
Drive conforms to: ATA/ATAPI-5 T13 1321D revision 3: 2 3 4 5
BTW I set udma2 (hdparm -X udma2 /dev/hda) otherwise there was no star.
No difference in performance (below).
----------------------------------------------------------------
hdparm -tT /dev/hda
/dev/hda:

(maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
