try this remedy
test a speed of your disk
hdparm -Tt /dev/hda
optimize parameters for HDD
hdparm -c1 -d1 -u1 -m16 -A /dev/hda
and test again
hdparm -Tt /dev/hda
if it worked for you add a file into /etc/init.d as startup script
#! /bin/sh
set -e
case "$1" in
start)
echo -n "Setting Drive Parameters: "
/sbin/hdparm -q -qc1 -qd1 -qX66 -qm1 -qu1 /dev/hda
echo "/dev/hda"
;;
*)
N=/etc/init.d/$NAME
echo "Usage: $N {start}" >&2
exit 1
;;
esac
exit 0
and link it from /etc/rcS.d
ln -s /etc/init.d/hdparm /etc/rcS.d/S01hdparm
Now your system will comeup with optimized setting for you HDD.
In case of my new computer it kicked from 2MB/s to 40MB/s with kernel 2.4.18-bf.
NOTE: kernel should be compiled with support DMA for HDD otherwise you will not
get significant performance improvement for your disk.
Good luck
