No i doszukałem się czemu mój(i nie tylko)od czasu do czasu pyka!.
Jest to najnormalniejsze w tych dyskach i nazywa sie Wear Leveling.
Przeczytajcie zresztą sami:
Western Digital has developed a firmware update to reduce the mechanical
noise associated with our wear leveling feature. Several customers have
contacted us about this increase in noise and their concern that the drive
may be malfunctioning. Aside from the audible noise, this operation is
normal and actually improves drive reliability by reducing the time a head
spends in the same location when the drive is at idle. The wear leveling
feature is non-destructive and the additional noise is not an indication of
potential drive failure.
Wear leveling is implemented on Western Digital Caviar drives to improve
long term reliability by preventing excessive wear on any one area of the
media by the heads (much like a screen saver program on a monitor). This
feature is activated when the drive is at idle (spinning under power) but no
drive related activity is present. The firmware will gradually move the
heads over the disk surface in small increments such that the entire disk
surface will be traversed over time.
