Think I solved it:
sudo hdparm -A1 -d1 /dev/hda
sudo hdparm -B 255 /dev/hda
Actually, I think it's just the 2nd line that does it, but at the same time
for different issues I added the first line to the script that I run right
after booting. Seems fine now. I'm not sure why this didn't work the first
time I tried it. The only thing I can think of that might be relevant is that
I did a re-install of my os (etch) about two months ago, from an os
(half-assed etch) that had numerous problems from a defective installation.
Thanks for the help,
