HDD XVR CCTV WD disk recovery help

[PinkPanda]

Hello to all , I need your help with recovering video records from my XVR device
So let's start at the beginning , my company was asked by the local police department for recordings from one of my cctv camera
One of my employees was happy to do it , and I let him (my bad) , for faster transfer he unpluged the disk from XVR device and plugged it in to PC (idiot)
He thought that the disk will magically appear under My Computer, seein this I transfered the HDD back to the XVR but now the device can't mount the disk
I only have the format option available.

I know that the HDD is probably encrypted and using different partition then Windows.

I gather some information using DMDE tool:

Disk name :
WD WD20PURX-64P6ZY0:80.00A80:WD-WMC4M0E81HWX

Code:

I think the disk is using EFI partition but I'm not expert when it comes to HDD recovery.

Could someone point me in the right direction and help me to recover files from this hdd , or make it usable in XVR.

Thank you

That's a Microsoft MBR:

Disk Editor View of the Windows 7 / 8 / 10 MBR:

The partition table has been cleared.

It's a protective MBR without a valid signature. You should clone the disk regardless what's in the MBR.
