I've upgraded my NVR8-7300 using the 'NVR8-7400_151224.zip' file and then noticed my HDD showed 'good' in the S.M.A.R.T. tab but 0GB in the HDD tab. I initialized/formatted with no change. Then checked auto update and am now updated to latest firmware (my NVR model now shows as NVR-1616?), however my HDD is still smart testing as good but showing 0GB, even after multiple initializations.
Any help is much appreciated.
