Notes
When alarm or sensor recording is performed repeatedly with Repeat Recording set to “ON”, data in the hard disk may become
fragmented. Continued use of such data may cause files to split up and recorded into free space, thereby giving rise to fragmenta-
tion or decay of data and subsequently slows down the speed extremely during hard disk search. This is where the “DEFRAG
DATABASE” feature comes into play in the maintenance of the hard disk.
It is also recommended to “FORMAT” (Initialize) the hard disk on a regular basis to avoid data fragmentation. When there is
insufficient hard disk space, create a backup data and format the disk to create space for the recorded data.
• It will interrupt the recording and perform
defrag if the time of the automatic execu-
tion is reached during recording.
Recording will be resumed automatically af-
ter defrag has been completed.
