Comment 126 for bug 67810

when i shutdown my laptop it still have a "PARK" sound
after apply the fix it wont work . too

I'. using Lenovo Y400
HDD is Western D 80GB SATA

this is the fix i apply

Simply write a file at "/etc/rc0.d/S00hdd-shutdown-workaround" which includes this two lines:

#!/bin/sh
echo 1 > /sys/class/scsi_disk/0\:0\:0\:0/stop_on_shutdown

If you have more than one directory at "/sys/class/scsi_disk/" try to find out which of it is your internal harddisk (e.g. "cat /sys/class/scsi_disk/a:b:c:d/device/model") If you have more than one harddisk add another line for each of them.

Then make it executable ("chmod +x filename")

Any Idea this is killing me.......
