I'm having problems mounting the recovery image. I've tried to mount the image multiple ways.

quark@DS9 ~ $ sudo mount -t ext4 /media/jump1/1recover/sdb1.img /mnt
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so


quark@DS9 ~ $ sudo mount -r -o loop /media/jump1/1recover/sdb1.img recover
mount: you must specify the filesystem type

quark@DS9 ~ $ sudo mount /media/jump1/1recover/sdb1.img mnt
mount: you must specify the filesystem type

It doesn't even give me detailed information on the file I just made, nautilus says it's 160gb.

quark@DS9 ~ $ file /media/jump1/1recover/sdb1.img
/media/jump1/1recover/sdb1.img: data


quark@DS9 ~ $ mmls /media/jump1/1recover/sdb1.img
        Cannot determine partition type

I'm not sure what I'm doing wrong or if I started this process incorrectly from the beginning. I've outlined what I've done so far below. I'm clueless, I'd appreciate if someone had some input for me.

What I have done from the beginning

My laptop has two hard drives.

One has the dual boot Win7 / Linux Mint system files. Secondary one contained my /home folder.

The laptop was jarred and the /home disk was broken. I tried a LiveCD recovery, it failed. Wouldn't even load a Live session with the disk installed. So I turned to ddrescue.

quark@DS9 ~ $ sudo fdisk -l

• sda - 160g internal, holds all system files and all computer functions.
• sdb - 160g internal, BROKEN, contains about 140g of data I'd like to recover.
• sdc - 1T external, contains recovery image. Only place that has space to do all this.

From this site, https://apps.education.ucsb.edu/wiki/Ddrescue

I used this script to create an image of the broken hard drive. I changed the destination to the external USB drive.

#!/bin/sh 

prt=sdb1
src=/dev/$prt
dst=/media/jump1/1recover/$prt.img
log=$dst.log

sudo time ddrescue --no-split $src $dst $log
sudo time ddrescue --direct --max-retries=3 $src $dst $log
sudo time ddrescue --direct --retrim --max-retries=3 $src $dst $log

Everything looked like it came off without a hitch:

quark@DS9 ~ $ sudo bash recover1

It looks like, from where I'm standing it worked perfectly. Here's the log:

# Rescue Logfile. Created by GNU ddrescue version 1.14

I'm not sure how to proceed. Does this mean all of my data is lost????????

Appreciate ANY input!
