You can upload your sector dumps here.

BTW, if you have access to the DVR, install a donor drive and allow the DVR to format it. Then you will see what sector 0 looks like. If you're lucky, it will be the only sector that has been "initialised", in which case it may be that the solution is as simple as patching its contents into your patient (or clone).

Windows only initialises sector 0. If the client has then created partitions and formatted them, then that's a different story. Show us something at least.

No partitions defined in sector 0. Some MFT fragments further out on drive created 11/9/2019, can not find much else. Many zeros. Some sort of table structure, a FAT?

I'm not sure I even understand what you ask and I also don't understand the obsession with the first sector.

In some cases, if i know what file system is used by DVR and client format or reinitialized drive, so I put back first few sectors of file system and easily recover clips.

If only initialized, did you scan with a tool with broad file system support, like R-Studio, ReclaiMe, UFS Explorer etc.?
