Maybe there is some kind of all-purpose ATA command that instructs the
disk drive to park the heads? Jens, could you give us a hint on how a
userspace application would do that?



Dunno if there's something that explicitly only parks the head, the best
option is probably to issue a STANDBY_NOW command. You can test this
with hdparm -y.


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. ;-(
