Damaged Drive with Question on TestDisk Output

#1 Post by Imhotep1963 » 06 Dec 2012, 18:43

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 running OSX 10.6.8

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

Code: Select all

ddrescue -r 3 -S /dev/rdisk5 /Volumes/goFlex/JJ/JJ_Recover.dmg /Volumes/goFlex/JJ/JJ_Recover.log
Upon completion, I tried to mount the image by double-clicking it but received the error:

Code: Select all

"No mountable filesystem"
So I tried using hdiutil:

Code: Select all

sudo hdiutil attach -nomount /volumes/backup/jj-recover.dmg
Success!

Code: Select all

/dev/disk5
So I try to mount:

Code: Select all

sudo mkdir /volumes/jj-drive
sudo mount -t hfs -r /dev/disk5 /volumes/jj-drive
Error:

Code: Select all

hfs: failed to load catalog file
So I ran Testdisk and got this information:

Code: Select all

Disk /dev/rdisk5 - 1000 GB / 931 GiB - 1953525168 sectors

Write isn't available because the partition table type "None" has been selected.

TestDisk exited normally.
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.

I appreciate any and all help!! Thank you!

Honestly it doesn't look very good. Have you try PhotoRec to recover some data ?
