• The HDD is very delicate. If used
improperly or in an unsuitable
environment, it is possible that the HDD
will fail after a few years of use. Signs of
problems include playback unexpectedly
freezing and noticeable block noise
(mosaic) in the picture. However,
sometimes there will be no warning
signs of HDD failure. If the HDD fails, no
playback of recorded material will be
possible. In this case it will be necessary
to replace the HDD unit.
Optimizing HDD performance
As you record and edit material on the HDD,
the data on the disk becomes fragmented,
eventually affecting the recorder’s
performance. Before this happens, the
recorder will warn you that it is time to
optimize the HDD (which you can do from
the Disc Setup menu; see
Optimize HDD
on
page 105).
