One more info:
If you have laptop-mode-tools installed, disabling hdd power management
(hdparm -B 255 /dev/sda) don't fix the problem.
Load_Cycle_Count still increase.
Only removing laptop-mode-tools don't fix the problem.
Is necessary *remove* laptop-mode-tools *and* do:
#hdparm -B 255 /dev/sda
Note that that should be 254. 255 gives undefined behaviour for lots of
hardware.
Here's a question to everybody here: does the load cycle count increase
quickly *while you're on AC*?
(Why I'm asking: the current solution was designed so that the load
cycle count increases while on battery, but stops increasing while on
AC. The theory is that nobody works on battery 24 hrs/day, and that HD
power management actually has benefits while working on battery. We've
calculated that with this solution, even with very mobile usage patterns
your drive should live for years. If the load cycle count increases
while you're on AC, then the solution is broken. If the load cycle count
increases only on battery, then it works as designed.)
Cheers,
Bart
