CentOS - Aug 2020 - DVR recorder how to resucue files

It looks like you've backuped an entire disk that might contain partitions.
So first check if you have partitions inside:

sudo fdisk -lu save.dd

If you have partitions inside, use the start offset of the partition to create a
loopback device (e.g. a partition starts at 56):

sudo losetup -o $((56*512)) /dev/loop0 save.dd

Now you should be able to use the partition. First check and than mount it:

sudo fsck -fv /dev/loop0
sudo mount /dev/loop0 /mnt

Hallo,
no partions are shown with dd.
Found an article that some DVR vendors are using their own filesystems.
I think that I ve no chane in this case to rescue anything.
Thanks for all hints.

dd does not show partitions, fdisk does (or parted or ...).

Regards Thomas

dd does not show partitions, fdisk does (or parted or ...).

Sorry,
my mistake.
I used several disktools.
