5.6.1 - HDD
This function gives you the option of formatting your NVR's hard drive, and it will be listed here for
selection (if a new hard drive has been installed inside your NVR, you need to format the drive before it
can be used).
Format HDD: Click the checkbox to select the hard drive then click this button to format. You have three
options to select from:
• Format the entire hard disk. All data will be erased: As stated, all data including events, log files and
analytic information will be erased.
• Only format the record partition. All record data will be erased: Only data such as videos, snapshots
and log files will be erased. All analytic information will be kept.
• Only format the general partition. All AI related data may be erased: Only analytic information will be
erased. Videos, snapshots and log files will be kept on the hard drive.
Select the relevant option, then click OK. Input your password, then click Authenticate. A message will
appear noting the data that will be erased. Click OK to continue.
Overwrite: This instructs your NVR to overwrite the oldest video files as the hard drive becomes full. You
also have the option of selecting the amount of days for recordings to be kept before they are overwritten.
For example, if you choose the option 7 days then only the last 7 days' recordings are kept on the HDD.
To prevent overwriting any old recordings, select OFF. If you have set Off on this feature, please check
the HDD status regularly to make sure the HDD is not full. Recording will be stopped if HDD is full. We
recommended leaving the Auto selection as this prevents your NVR from running out of storage space.
