You need to use hdparm to tweak your harddisks parameters. Be very careful
though. Most importantly, make sure you have a ATA66-compliant IDE cable.
I had machine with an ATA66 drive and the cable was only rated for ATA33.
I tweaked the drive with hdparm and got a little performance boost, but
when I rebooted, the filesystem was toast :) I later discovered the cable
problem when I threw FreeBSD on the machine and Free's kernel told me that
my cable was non-ATA66 compliant and that it was reverting my drive to
ATA33 mode :) FreeBSD rocks.
