difficulty mounting ???unknown (I thought EXT3) to access recorded video files


I have a Panasonic 50ST60A plasma TV with it's own 'built-in 'PVR', I have a few recordings on it which I would like to keep & therefore edit out adverts etc on a Linux video editor program. This is quite a simple task with most PVRs (including my wonderful Mediastar with which I use VideoRedo on XP), but the Panasonic 'inbuilt PVR' appears to be proprietary & therefore you can't access the recordings on any other device/PC etc.
The HD isn't even recognised as a drive when I plug it into my PC.
Some people have suggested that the HD for the Panasonic in-built PVR is formatted to EXT3, but when I put in a USB port on my PC, with Lubuntu as the operating system, or as I have currently- a live CD of LMDE MATE (which is quite fast btw) it won't mount- this is the message I get-

Error mounting /dev/sdb1 at /media/mint/disk: Command-line `mount -t "ufs" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdb1" "/media/mint/disk"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so


When I use g-parted the partitions are under 'information' noted as;
Unable to detect file system! Possible reasons is damaged. The file system is unknown to gparted. there is no file system available (unformatted). the device entry /dev/sdb2is missing.

Is there something else I can try? Is there a terminal command to try?

If the entire partition is encrypted, you might not be able to access it except from the original PVR.
You might want to consider trying TestDisk as an attempt to recover the media files. (this will only work if the drive/files are not encrypted)

You could try a
Code:
sudo fdisk -l
For example, the 2 digit id (83) for ext4 is listed in https://en.wikipedia.org/wiki/Partit..._partition_IDs
So you could try and "guess" what the file system is...

Don't you have the option to save to USB/SD from the TV ?. Might be a better option.
I taken the hard disk from a Panasonic stand-alone PVR, but immediately reformatted it for use elsewhere - never checked what format is was in.

you may be able to that- but that's is just the medium one is recording to. This is a TV with an in-built PVR function, so it's not a separate stand-alone PVR unit. Regardless- one has to format the External HD using the TV when it is used to record for the first time, otherwise you can't record to it......

I meant; can't you copy/save it to a USB/SD without removing the hard disk from the TV ?.
This should give you a copy you can edit on a Linux system.
