Verify
Click Verify on Figure 6-42 to check the disk status. Three types of check disk actions can be
initiated through this button.
Bad block: Performs read/write test to drive sectors to locate bad blocks. This action may take
several hours to complete.
Fast S.M.A.R.T.: Tests the electronic and mechanical performance and disk read performance,
including those on disk buffer, read head, seek time, and integrity of drive sectors. The short
test is performed on a small section of disk platters, and takes about 2 minutes to complete.
S.M.A.R.T.: The long test is more thoroughly and is performed to all drive sectors. The actual
completion time depends on drive sizes and the attributes put to test.
The Check disk functions mentioned above, when performed during active I/Os, can consume
system resources and cause dropped frames with the recording tasks.
Note
Disk verify function requires a volume to be temporarily
disabled; namely, the video recording will be stopped before disk
verify can be performed.
