Hi,
maybe rather than trying to mount the disk earlier, you could try
to spin it up so that it mounts when mountall is run.

>From https://unix.stackexchange.com/questions/10930/what-command-do-i-use-to-spin-up-a-power-up-in-standby-drive:

             Drives supporting the "Power-up in Standby" feature are supposed to spin up as soon as they get
             a command that requires reading the disk.

             like dd if=/dev/hdX of=/dev/null count=512

------------------------------------------------
#/bin/dash

 ### BEGIN INIT INFO
 # Provides:          disk
 # Required-Start:
 # Required-Stop:
 # Default-Start:     S
 # Default-Stop:
 # Short-Description: prepare disk at boot time
 ### END INIT INFO

case $1 in

start)
# Edit this:
/bin/dd if=/dev/disk of=/dev/null count=512
;;

esac
------------------------------------------------

eventually you could make this an udev/eudev rule
to be run when the drive is detected.

Untested, just my 2 cents,
