  Speaking of hdparm, I just recently found out that in Linux, HDs have DMA
off by default. By using hdparm you can speed up your HD up to 10 times the
original speed, by issuing the following command each bootup (replace
/dev/hda with your UDMA HD)...

  hdparm -c1 -d1 -m16 -k1 /dev/hda

Try it by first issuing:

  hdparm -Tt /dev/hda

for a benchmark and then repeat the benchamrk after turning DMA on.
