DISK MANAGEMENT
■ Notes on the 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 3
areas 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.
It is possible to check the available disk space for each
area on "Disk Info" of "Maintenance" on the SETUP MENU.
(Refer to page 94.)
• When connecting an optional extension unit (WJ-
HDE300 series), it is possible to create a pre-recording
area to perform pre-event recording (page 135) for up
to 60 minutes.
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 131.)
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.
