NOTE!
Some hard disks only support some of the test items.
The system provides three test types: Short, Extended, and
Conveyance. Extended tests detect more thoroughly and thus take
longer time than Short tests. Conveyance tests mainly detect data
transmission problems.
CAUTION!
Using a faulty disk is risky. Faulty disks should be replaced immediately.
Contact your local dealer for information about hard disks.
Bad Sector Detection
Bad sector detection checks for bad sectors in hard disks.
1. Click Maintain > HDD > Bad Sector Detect.
2. Select the desired disk and detection type, and then click Detect to
start detection. Click Stop if you want to stop.
CAUTION!
The detection stops automatically when the error count reaches 100.
Health Test
Health test is supported by certain NVR models.
