Trying to solve the click of death issue

[Fulko Hew]

I had to get a new laptop, and it came with a Toshiba MQ01ABD100 drive.

To disable the Advanced Power Management and to stop the head
unload/clicking I've always used:

hdparm -B 255 /dev/sda

But on this machine/drive, it doesn't seem to work;
or at least it only works for a short while, and then it starts unloading
again.

More importantly, the next time I try to disable it,it says its disabled,
but the drive carries on clicking, and the Load_Cycle_Count still keeps
going up.

Suggestions anyone?
