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?
