DISK MANAGEMENT

■Notes on hard disk

Camera images are recorded into the built-in hard disk of this unit.

There are two hard disks in this unit. In case one of them malfunctions during recording, it is possible to keep record- ing with the other hard disk (mirror function).

The internal hard disk of this unit is virtually divided into areas 4 to manage the hard disk.

Normal recording area: An area into which images are recorded at times other than an event occurrence such as manual recording.

Event recording area: An area into which images are recorded at an event occurrence.

Copy area: An area into which copy data is stored.

Pre-recording area: An area into which pre-recording images are recorded.

It is possible to check the available disk space for each area on "Disk Info" of "Maintenance" on the SETUP MENU. (Refer to page 93.)

Operations for the hard disk drive such as initialization (for- matting) of the hard disk drive in the unit or the optional extension unit, or mirroring, etc., can be performed in the "HDD DISK MENU". (Refer to page 130.)

Note: It is necessary to create either the normal recording area or the event record area. If the normal recording area is not created, manual recording images and schedule recording images are recorded into the event recording area. If the event recording area is not creat- ed, event recording images and emergency recording images are recorded into the normal recording area.

■How to replace the built-in hard disk

It is possible to replace the hard disk drive regardless of whether the power of the unit is on/off.

However, the procedures for replacement are different. Refer to the operating instructions for the optional extension unit when replacing the hard disk in the extension unit.
