I got a case from SAMSUNG DVR 3200.
Successfully I cloned the drive, but while I checked the clone copy I saw the drive has a NTFS FORMATTED VOLUME/PARTITION, checked using GDB for NTFS (during the scan it showed files r getting detected in several sectors), after the complete scan it didn't show any files.

Any idea?
Does it carry other file system instead of NTFS?

I would use UFS Explorer, as it supports many file systems.

But anyway, you say you saw a NTFS partition. Have you checked MFT records, to see if they are there.

Why not start by examining sector 0 with a disc editor?

Tested UFS Standard DEMO, it did not find partitions but found files by INTELLRAW scan.

Seems it produced correct result.

Preparing to get the License for UFS Standard.

That may mean that the file system is proprietary, but the file types are common.

UFS Explorer produces MPEG files but all are corrupted.

Even simpler : see how the user configured the box and look for the "right stuff" between the LBAs , a clue : 4 - instead of having "standard expectations" :mrgreen: Unfortunately I can't say more, Shahij, but get the hint.
