Defrag
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.
