[sleuthkit-users] AVTECH 773-M video files recovery

[Marco L. <mf...@gm...>]

Hi,

I'm trying to recovery video data from a disk used with a DVR AVTECH 773-m
(ADV7171 chipset); if I insert this disk into the DVR it can't read it
giving an 'empty disk' error. I'm quite sure the data is still into the
disk.

It seems that the DVR write raw data to the disk, none of the tools I've
used was able to retrieve any file system or partition information.

I've tried to do some reverse engineering using a working disk that has a
couple of recording but at the moment I'm not makeing any progress.

Photorec recovered files from the not working disk but it seems they are all
false positive.

Do you have any information about data format used by AVTECH?
Can you suggest tools/path to follow to try and recover the data?

Thank you very much in advance for helping.

Ciao.
