I just tried your setup command a got an interesting result.
With my hdparm command (in /.etc/init,d/hwtools)
hdparm -q -m16 -a12 -A1 -c3 -d1 -u1 -W0 -S150 /dev/hda
I got
hdrarm -Tt /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 1.07 seconds =119.63 MB/sec
Timing buffered disk reads: 64 MB in 2.96 seconds = 21.62 MB/sec
I had not used the -X34 before so I tried it. :-(
hdparm -q -m16 -a12 -A1 -c3 -d1 -u1 -W0 -S150 -X34 /dev/hda
gave me
hdrarm -Tt /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 1.07 seconds =119.63 MB/sec
Timing buffered disk reads: 64 MB in 7.47 seconds = 8.57 MB/sec
I see the suggested use of the -X?? in the man page but it sure
doesn't help here.
hdparm -i /dev/hda

Computers are a more fun way to do the same work you'd have to do
without them.
