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 Kind regards Thomas Am Mi., 26.
