HDD Auto Scan
When the NVR found file system error while recording, the NVR will reboot
and HDD auto scan will be initiated. If by any chance auto scan failed, the
HDD will need to be formatted.
NOTE:
If users wish to initiate HDD auto scan function for abnormal
power loss as well, enter the OSD setup menu via an authorized
account and access <Database> to set <Repair On Power Loss> to
<On>. HDD auto scan will be initiated every time the NVR powers on if
it previously loss power abnormally or if there is file system error.
Read the following troubleshooting to finish the auto scanning process.
Skip Auto Scan
: During the scanning process, users can click to skip the
process.
Time Expired
: When the scanning process took more than predetermined
time (3hrs for 1TB HDD, 6hrs for 2TB HDD, etc.), the scanning process is
treated as failed and will be automatically terminated. The NVR will reboot.
Format HDD
: If the scanning process is failed, users will be prompted to
confirm format of the HDD with error. When users confirmed to format the
HDD with error, login of an authorized account is required if password
protection is enabled. If users select cancel or do not respond within 5
minutes, the HDD with error will be marked as a NG HDD. A NG HDD will
not be counted as a part of the NVR

nothing.

and access <Database>. Then select <Internal Disks> and find the NG
HDD from the list. Under <Action> column, select <Format> to format the
NG HDD. Then select <Add> to add the formatted HDD to the database.
