j. What are the differences between the three different ways of formatting a hard drive?

Answer:

Your NVR offers you three ways to format your hard drive.

1. You can choose to format the entire hard drive. Doing so will delete all data.
2. You can also choose to format only the video partition of the drive. In this case, all video files will be deleted but other data will be left as is.
3. You can also choose to format only the general partition of the drive. In this case, all AI related data will be deleted but everything else will be left as is.
