How to restore the partition of the DVR after formatting?

Question

USB flash drives

Hey!
In the video recorder, a flash drive with the necessary videos was formatted. The main problem is that the video is written incomprehensibly as on a flash drive and it is almost empty, on the flash drive there is only the X2Player.exe player with which you can view these videos and Default_Folder.ini (hidden), FAT flash drive layout.
Tell me how to get video from a flash drive?
Is it possible to restore a completely formatted partition on a flash drive in order to try to run the player?

Answer 1

The possibility of recovery largely depends on how exactly the DVR stored the recordings on the memory card: some car DVRs store video in the form of ordinary video files, some in a proprietary closed format, or even use their own storage partition format, recording a continuous video stream there with internal markup.
The second option in our time is widely used in stationary video recorders (CCTV and security systems, they are also CCTV DVR).
If you say that the card has been formatted, then you need to know more about this. This fact hints at the second option above - the user took out the memory card, connected it to the computer. Windows, of course, did not recognize the proprietary format, did not see anything there and offered to format the card. Ales.
If this is the case, then unfortunately no standard data recovery programs will help - they are designed for traditional standard file systems and file recovery.
Although for safety net you can scan the map using, for example, R.saver.
We have programs for recovery from registrars, but they are still in beta testing, because. storage formats from different manufacturers are not standardized in any way and require preliminary reverse engineering.

If it doesn't help, then the only option is analysis manually and custom development of a recovery utility for your specific case.
To do this, you need to contact a really cool data recovery company that does development and has programmers on staff. Here is an article on how not to make a mistake whenchoosing a data recovery company .
However, in any case, I would advise you to first make a full sector-by-sector uncompressed copy (image) of the map. It can come in handy later, if all of a sudden, where you go, somehow screw up. This can be done using, for example, WinHex, CI Hex Viewer, Clonezilla, gddrescue.
If you can't find anyone nearby, you can contact us. We are engaged in the development and recovery of data from registrars .
This is one of the cases when you can recover data remotely, via the Internet.
