Here's the hdparm stuff I've stuck in rc.local on my home machine. As
Derek mentioned, however, your mileage may vary significantly...

# hdparm magic:
# -c 1    = enable 32-bit i/o support
# -d 1    = enable dma transfers
# -k 1    = keep settings through resets
# -m 16   = set multiple-sector i/o
# -u 1    = set interrupt-unmask flag
# -S 241  = power back drives after 30 min of inactivity
# -X 66   = use UDMA mode2
/sbin/hdparm -c1 -d1 -k1 -m16 -u1 -S241 -X66 /dev/hda
/sbin/hdparm -c1 -d1 -k1 -m16 -u1 -S241 -X66 /dev/hdc
