Synopsis: Weird Hard Disk clicking noise on system shutdown State-Changed-From-To: open->closed State-Changed-By: brucec State-Changed-When: Tue Nov 30 23:20:06 UTC 2010 State-Changed-Why: The clicking sound is an Emegency Unload being done as the drive loses power. This is fixed in stable/7 and stable/8 by spinning the disks down during shutdown if the cam subsystem is being used (i.e. ATA_CAM or ahci(4)). It's unlikely that the ata(4) driver will get the same fix since it's being deprecated in favour of ATA_CAM and ahci(4), and it has issues with power management.
