S.m.a.r.t - CONCORD CNK4242WPA-A Manual

5.5.2 S.M.A.R.T

This function can be used to display technical information on the hard drive installed inside your Wireless NVR. You
can also perform a test (there are three types available) to evaluate and detect potential drive errors.
Whole Evaluation not passed, continue to use the disk: If for some reason the hard drive has developed a fault
(such as one or more bad sectors), you can instruct your Wireless NVR to continue saving to the drive.
Self-check Type: There are three types available:
Short: This test verifies major components of the hard drive such as read/write heads, electronics and internal
memory.
Long: This is a longer test that verifies the above as well as performing a surface scan to reveal problematic areas (if
any) and forces bad sector relocation
Conveyance: This is a very quick test that verifies the mechanical parts of the hard drive are working.
Note: When performing a test, your Wireless NVR will continue to work as normal. If an HDD S.M.A.R.T error found,
the HDD can be continued to use, but there will be a risk to lose recording data. It is recommended to replace a new
HDD.
