The average laptop HD life can typically stand :

So it's quite normal (and desirable) that you load-unload heads much
more frequently than you spin the disk.

Hi Colin,
I'll perform the checks you suggest, however I doubt the issue is caused
by apps performing unwanted writes (I assume that the disk restarting

issue is not with the disk restarting, but with the disk stopping much
too
@Swâmi,
I'm suspecting it may be that Precise is doing less disk activity now

causing a load of (frequent) unnecessary writes. I wonder if the
