Bad Sector Detection Tab
This tab tests your hard drives, hopefully finding errors before they
cause a problems for your system.
At the top, select the hard drive you want to test using the HDD No.
dropdown menu. You can only test one hard drive at a time. Then
select the type of test you want to perform in the dropdown next to
the hard drive.
There are two types of tests: key area detection does a quick scan of
only the critical portions of each sector of the hard drive, and takes
less than a minute; full detection runs an exhaustive testing of the
entire hard drive surface, and will take multiple hours to complete,
depending on the size of the hard drive.
Press Detect to begin the test. The tests do not suspend surveillance
or recording.
As the test executes, it fills in sectors that have been tested with
green (for sectors that passed), red (for sectors that didn’t), or yellow
(for partitions on the drive that are inaccessible to the recorder).
Below this section are various technical data about the hard drive
and the current test (if any).
Next are several buttons:
Error Info: lets you review details of any errors encountered.
Pause (or Resume): suspends or resumes execution of the test.
Cancel: Stops the test completely.
