(Get the code!)
So , the hard disk doesn't exactly go into suspend when the disk head is
parked, so the kernel doesn't get to know that the disk head is
parked(because standby=>parking) - it interprets this as a sign that the
hard disk is in Active/Idle mode.So it doesn't bother stopping data from
being written to the disk - this will inevitably cause the head to
unpark from the ramp.What do you guys think of this ?I think the problem
is associated with the way in which the standby command is issued (by
the kernel?).My disk never went to standby on laptop-mode , just a bunch
of head parkings.
.I used hdparm to find the mode of the HD.Hdparm doesn't wake up the
disk from standby by state -in contrast to smartctl.
