Modern IDE drives sometimes lie about having finished writing out the data, when in fact it's still only in cache. You should be able to disable this behaviour to test (try the BIOS).
I have a "HDD Post Write Buffer" in the BIOS according to the MB manual
although the disks aren't connected to the MB controllers they are on RAID 5 set off a PCI-X card. Will give it a go tomorrow ( drag the monitor
back to the rack ). Will this have any performance penalties? I could
just avoid using shutdown -p but it seems a bit dodgy what its doing.
If this machine where miles away without remote console it would have
caused major amounts of pain.

Why would you use shutdown -p on a remote machine anyway. I could see possibly a shutdown -r but -p come on.
