When you fail to playback the video of the NVR, the formatting failure is displayed when formatting the HDD, or when you find the red led in front of the NVR stays solid red and failed to format the HDD, here are some possible causes for your reference.
Cause 1: The firmware version of the NVR is quite old.
Please find out the firmware version of the NVR and click here to download and unzip the package to upgrade it.
Cause 2: Format the HDD immediately after rebooting the NVR.
If the NVR hasn't loaded all the storage on the HDD after reboot, it will lead to formatting failure. Please wait for the video to be fully loaded before formatting.
Cause 3: Software issue
Please restore the NVR to test whether the issue can be fixed.
Cause 4: Defective HDD.
If possible, please unplug the original HDD and use another HDD to test whether the NVR can work normally. If yes, please contact support for a warranty. Please click here to learn how the change the HDD.
Cause 5: The compatibility issue between HDD and NVR.
If the HDD is the original one that comes with the NVR, please ignore this.
