Pioneer DVR-640H-S Symbols used in this manual, Optimizing HDD performance

Before you start

•Do not move the recorder immediately after switching it off. If you need to move the recorder, please follow the steps below:

1 After the message POWER OFF is shown in the display, wait at least two minutes.

2 Unplug from the wall socket.

3 Move the recorder.

•If there’s a power failure while the recorder is on there is a chance that some data on the HDD will be lost.

•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).
