Filesystem Problems with DMG

Hi all! I have a task that has been giving me problems.I have my sister-in-law's external hard drive that has been damaged and the filesystem is not mountable.

I am on a Mac running OSX 10.6.8

Using ddrescue, I recovered the contents and transferred to my external drive:

Code:
sudo ddrescue -v /dev/disk5 /volumes/backup/jj-recover.dmg jj-recover.log

Upon completion, I tried to mount the image by double-clicking it but received the error:

Code:
"No mountable filesystem"

So I tried using hdiutil:
Code:
sudo hdiutil attach -nomount /volumes/backup/jj-recover.dmg

Success!
Code:
/dev/disk6

So I try to mount:

Code:
sudo mkdir /volumes/jj-drive
sudo mount -t hfs -r /dev/disk6 /volumes/jj-drive

Error

Code:
hfs: failed to load catalog file

So I ran Testdisk and got this information:

Code:
Disk /dev/rdisk5 - 1000 GB / 931 GiB - 1953525168 sectors                       
     Partition               Start        End    Size in sectors                
>P CramFS                 313874337  319333484    5459148 [     L  ^Og~Yo]      
 P HFS+                  1952521844 1953058783     536940


1952521844
1953058783

So here I am debating what to do. I was hoping that someone may have had similar issue or may have some recommendation as to what to do next.

I appreciate any and all help!!

Thank you!
