Not sure about hotpluging, but for the reboot
/etc/rc.d/rc.local might be a good place to try this:
#!/bin/sh
#
# This script will be executed *after* all the other init
# scripts. You can put your own initialization stuff in here
# if you don't want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
# turn off DMA for hde WD drive
# -d0 = off
# -d1 = on
# hdparm -d0 /dev/hde
# set sector count for multiple sector I/O
# WD drives like a low setting
# to prevent I/O data errors.
# hdparm -m2 /dev/hde
Kind Regards,
