    This is exactly what I said. Use hdparm to make the HD park
    inmediatelly. I did send the email to the HDPARM developer, but he never
    replied. I asked him what would be the best way to make the HD park with
    no exception and then let it come back 5 or 10 seconds later.

    Never heard back. ;-(
