** Description changed:
Binary package hint: hddtemp
running httdtemp normally or as a daemon causes unnecessary disk
activity. It is important for laptop users to reduce unnecessary disk-
activity because the harddrive head might be parked or the drive might
be spun down.
IMHO hddtemp should not need to access the harddisk after starting up
unless configured for logging.
I'm seeing things like this when using btrace :
