Pioneer DVR-920H About the internal hard disk drive, Optimizing HDD performance

Before you start

•Do I need two DVD recorders for editing? What kind of editing can I do?

Unlike editing video tape, you only need one DVD recorder to edit discs. With DVD, you edit by making a ‘Play List’ of what to play and when to play it. On playback, the recorder plays the disc according to the Play List.

Original

Title 1			Title 2		Title 3
Chapter 1	Chapter 2	Chapter 3		Chapter 1		Chapter 1	Chapter 2

Title 1		Title 2
Chapter 1	Chapter 2		Chapter 1	Chapter 2

Play List

Throughout this manual, you will often see the words Original and Play List to refer to the actual content and the edited version.

•Original content refers to what’s actually recorded on the disc.

•Play List content refers to the edited version of the disc—how the Original content is to be played.

About the internal hard disk drive

The internal hard disk drive (HDD) is a fragile piece of equipment. Please use the recorder following the guidelines below to protect against possible HDD failure.

We recommend that you back up your important recordings onto DVD-R/RW discs in order to protect against accidental loss.

•Do not move the recorder while it is on.

•Install and use the recorder on a stable, level surface.

•Do not block the rear vent/cooling fan.

•Do not use the recorder in excessively hot or humid places, or in places that may be subject to sudden changes in temperature. Sudden changes in temperature can cause condensation to form inside the recorder. This can be a cause of HDD failure.

•While the recorder is switched on or the front panel display shows EPG, do not unplug from the wall socket or switch the electricity off from the breaker switch.

•Do not move the recorder immediately after switching it off or while the front panel display shows EPG. 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 103).
