Use the hdparm command (as root).  The command would be something
like: hdparm -d 1 /dev/hda (or whatever your disk is).  Also look at
the manpage for the -c and -m, and possibly carefully try the -u
option.  If you don't have hdparm, install the hwtools package.  You
can edit the /etc/init.d/hwtools file to run the appropriate command
during boot.  My bios also has a setting to enable or disable dma, and 
I am not sure if hdparm can override that.

Nobody has mentioned this, but using audio for mp3 files drastically
slows down my disk, as well as running 'esd' whether or not it is
being used.  Try checking your disk speed with 'hdparm -Tt /dev/hda'.
If you use 'esd', try checking speed with and without it.
