Dahua NVR, footage randomly getting deleted??

never had this issue with any NVR i have used in the past for the last 15 years, still doesn't explain why a section of footage was there one day and gone the next for ALL cameras.
Does the NVR have the ability to see the HDD SMART attributes, as Hikvision NVRs do?
If so - that will confirm the state of health, or lack of it, of the HDD.
 
Isn't that just swapping drives because one is full?

I'm on a NVR5216-16P-4KS2E with FW V4.002.0000000.3.R, Build Date: 2022-03-22

and I get these, do you not have any of them?

Its not a FW thing I wouldnt go down that rabbit hole.
I was simply inquiring on the newer version. Im happy with the one I have no need to risk borking things up if no problem.

Yep same. I have a brand new duplicate sitting there for just that reason.
