Check Disk Status

Hard disk failure often comes after detectable signs and thus can be predicable, thus it is

important to detect these signs long before they really cause disk failures.

NVR performs S.M.A.R.T. Disk check on 24-hour basis since last check. This technology

enables a system to monitor the disk status and anticipate disk failures, helping the system

administrator to prevent from unexpected outage and data loss.

You may manually perform an instant S.M.A.R.T check by clicking “Refresh”.

Once the disk a appears in “WARNING”, “FAILED”, or “UNKNOWN” status, it is not reliable

for recording, and may fail when the number of bad sectors on the disk has grown high

enough.
