You should probably investigate why commands in rc.local are not
working. Make sure the file is executable, and perhaps put some echo
commands in it to echo comments:

echo "Tweaking hardisks"
hdparm -c 1 -d 1 -k 1 /dev/hda
hdparm -c 1 -d 1 -k 1 /dev/hdb
sleep 3

Both the echo command and the hdparm commands (or whatever commands you
are using for UDMA) should print a message to your screen a boot. The
"sleep 3" gives you a chance to actually read them.
