Hi Shehab.
To use Testdisk, you don't mount the image. If you could mount it, why would you need to run Testdisk?
cd (directory where the image is)
sudo testdisk image.
That's it. If it can find partitions, have it write and fix the partition table, then try to mount the filesystem on one of the partitions:
cat /proc/partitions
sudo losetup /dev/loop1 image
cat /proc/partitions
(if you see /dev/loop1 along with /dev/loop1p1 or something like that, then try to mount them)
mkdir mnt
sudo mount /dev/loop1p1 mnt
Also, if photorec could not find your powerpoint file, then I would not get very excited about the files foremost found.
Regards,
Andrew Zajac

Hi Andrew! I appreciate your timely advice. I couldn't get to the stage where I could run Testdisk because I wasn't able to mount the image. Photorec however recovered the files (about a 108), though the integrity of the files is questionable. I was told that there was a powerpoint presentation on the disk (among other types of files), it seems to have recovered 'a' .ppt file but it contains only one slide. I had selected an option in Photorec that saves broken files as well (or something to that effect that I can't remember now).
I then also used Foremost, which has recovered about 5300 files, it created directories of the various file types. And under the .ppt directory I see a long list of .ppt files. I haven't had the time to look through them yet but I'm assuming these are fragmented bits and pieces of one ppt presentation?
Best wishes, Shehab.

Hi Shehab.
First, I would make a backup of the image. Then I would try running Testdisk on the image, to see if it can find and restore any partitions.
If that fails, of if the newly recovered partitions are still unmountable due to filesystem corruption, I would use Photorec (included with the Testdisk package) to try to carve files form the image.
That's it...

Received: Monday, October 18, 2010, 7:08 AMHi!
I have a 'corrupt' 4GB usb
memory stick that Windows says needs to be formatted. Linux (Debian Lenny) recognises it as /dev/sdc but will not mount it giving a very general mount error.
I was able to run 'dd' without any problems and made an image backup. I then ran 'ddrescue' as well to make another image without any problems (though I'm not sure if it was even necessary to run 'ddrescue in my case). So maybe the data itself is fine but only the partition table is corrupt?
When I had tried to run 'testdisk' on the memory stick, it returns saying that it can't find any partitions on the drive. I read some posts on this forum about trying to use data carving tools on the image like 'foremost'. I will try that when I get home but was wondering if someone has some more advice on how I should proceed. I need to access/rescue the files that are stored on the image created with ddrescue/dd.
Any help will be appreciated. I understand that ddrescue is doing its job and I need help with what to do with the rescued image.
Best wishes, Shehab.
