lg pvr rh1888h PVR Encrypted drive

[odedshankar]

Hi Guys,
I have got a 160GB HDD from a lg pvr rh1888h.
Data is encrypted on the fly, does anyone familiar with a way or tool to decrypt the drive?

It might be easier to repair the PVR.

Here is a service manual:

Did you somehow confirm it is indeed encryption and not some proprietary format PVR uses to store data?

[odedshankar]

yes it is encrypted and not the special formats.
There is no need to repair it as it is working - for some reason i think the customer clicked something and it initialized the disk so it shows empty.

Download this:
from-hdd-lg-to-pc-1.12.rar

http://ifndef.altervista.org/MaterOnlin ... -to-pc.zip
or
http://from-hdd-lg-to-pc.narod.ru/

This program should emulate on your PC the encrypted partition of your LG, if works you should be able to recover data.

Last version is 2.06, but beta:

I notice that the documentation for the "from-hdd-lg-to-pc" tool states that it applies to PVRs based around the LSI Logic / Magnum Domino DMN-8652 and DMN-8653 chips.

FWIW, I have a supermarket brand DVDR (TDR250HD) that uses the DMN-8652, whereas the RH1888H uses the DMN-8653. The TDR250HD's file system is "TFS2". Here is a partial analysis:

It might be a complete red herring, but here is the initial structure:

So, let’s have a look at the 2GB formatted disk.
