Nowadays we're supposed to trust the kernel to do it right, and your disk
should spin up only if it has crap firmware (unlikely).  Unless you're using
the deprecated "old ide" drivers (/dev/hd*), in which case all bets are off.

Please edit /etc/init.d/halt and make it not add "-h" to the halt invocation
(but make sure to add "sync ; sleep 5" before the halt command just in
case).  Does that fix the issue?
