Samsung DVR 3200 File System

[shahij]

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?

Try with R-Studio i had the same problem after scanning i found UFS inside try may be same u have ...

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?

sorry to delay...

I also sugest USF Explorer. It was the one that solved me a problem with a DVD recorder too.

Or else, post a screenshot of MBR.

UFS Explorer STANDARD EDITION OR PROFESSIONAL?

[dmarques]

Use UFS Standard.

[shahij]

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.

[dmarques]

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

[shahij]

UFS Explorer produces MPEG files but all are corrupted.

[dmarques]

Have you tried to talk with the manufacturer about it ?

[BlackST]

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" Unfortunately I can't say more, Shahij, but get the hint.
