You don't want to mount the image of the entire drive and then use testdisk on
it. But in Linux, you don't really need Testdisk to mount a partition on a
disk with a corrupt partition table, just set an offset when you mount the
(lost) partition. See here:
https://help.ubuntu.com/community/DataRecovery#Extract%20filesystem%20from%20recovered%20image
Basically, use mmls to show what partitions *seem* to be there and then mount
(or try to mount) the filesystem there by specifying an offset. All these
tools (mmls is found in The Sleuth Kit, testdisk, photorec, gddrescue) are
available in Ubuntu-Rescue-Remix)

Good Luck!

Greetings all,
I've recently had a hard disk crash with some data that I'm trying desperately
to retrieve. Photorec has pulled some of the photos that I need from it, but
not many (though it did pull about 19000 useless jpgs from temp files on the
windows partition. Lol). Photorec pauses about half-way through the disk and
then never finds any more pictures. No OS will assign a drive letter or see
the partitions, and testdisk doesn't see a partition table, it has to do a
"quick search" of the cylinders on the drive to find the partition table, which
it does successfully.
I tried (foolishly, I know) to write the partition table to the drive, and it
said it wrote it, but it didn't change any of my symptoms.
That said, what I'd like to do is us ddrescue to create an image of the problem
drive. If the partition table, etc., is corrupt, I'm not sure if I'll be able
to mount the image in linux to do much with the image, will I? Even if this
info is missing, can I still mount the image well enough to Testdisk it, fix
the partition table, then try to see the third partition with a (hopefully)
intact file system?
Thanks for your time!
Mike G.
