AVTECH 773M video files recovery May 31 2010 09:00AM

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.

Marco.
