HDD Detect
The HDD detect function is to detect HDD current status so that user may clearly understand the HDD
performance and replace the malfunction HDD.
There are two detect types:
Quick detect: It is to detect the storaged files on the HDD. User may use format function to repair the
bad track. System can not detect the bad track if there is no record on the HDD.
Global detect: It detects the whole HDD. The process may take a long time and may affect the HDD
that is saving the record. If it detects the bad track, it may result from the damaged HDD.
