The testdisk web site has a pretty good sample session so you can see
what it should look like.

It is still confusing. Here where I got stucked. Maybe someone can chime in.
Thanks.

Right from the beginning this sounds bad....
/Input/output error//
//Failed to read of MFT, mft=17625 count=1 br=-1: Input/output error//
//Inode is corrupt (5): Input/output error//
//Index root attribute missing in directory inode 5: Input/output error//
//Failed to mount '/dev/sdc1': Input/output error/
MFT tables are low level indexes in the NTFS file system, if they can't
be read
that's a big issue.
The screenshot here
http://forum.cgsecurity.org/phpBB3/help-with-restoring-usb-drive-t4953.html#p15748
looks like you already got the partition list and hit 'P' to see a list
of files.
You should be seeing a list of files and directories at that point, none
are visible
in the screenshot, another bad sign.
Was this after a deep scan?
Was the partition listed more than once, and if so did you try to view
the files in all
listings for the partition?
If the cradle for the goflex has SATA connectors that plug into the HDD
like the one
shown here...
http://www.amazon.com/Seagate-GoFlex-Desktop-Adapter-PCI-Express/dp/B00HWZ6OYC
My next step, would be to plug the goflex in to the SATA power and data
cable in a
desktop system. When plugged in on USB more is done in software, the
SATA controller
on the motherboard is better able to recover from errors if there is
more going on than
just filesystem corruption.
I've dealt with a few of the goflex drives and had to shave the plastic
on the SATA power
and data cable with a razor blade to get them to fit into the connectors
on the drive without
taking the enclosure apart.
Typically at this point I would run the Gnome disk utility, and do a
full smart test on the
hard drive. If the drive already has errors recorded that the disk
utility doesn't like it may
give you an indication of this when you run it. You can also view a
list of Smart data in the
disk utility. Pending remaps and uncorrectable errors are a couple of
the more significant
things to look at.
Sector remaps only happen on a write, so a handful of pending I would
not consider an
automatic failure, if you are getting into the neighborhood of ten or
more I would question
the reliability of the drive.
This could be done from the command line with smartmon tools, but I'm
not familiar with
it's usage.
If the disk physically looks good, then I would try testdisk again.
If you can get access to the files, you want to have another drive ready
to copy the files
to or enough free space on the drive you are running from to hold the files.
If you get an indication that the disk is failing, then the question of
how important the data
is to you comes into play, poking at a disk that is physically failing
could reduce the chance
of a professional data recovery service being able to recover the files.
If testdisk still doesn't show you and files and directories, then I
would try photorec.
Photorec doesn't do well with files that are fragmented, and if it can
recognize files may give
you numbers for names, instead of the actual file names, it does have a
brute force option
that will try to piece the file chains together and match the files to
names. The brute force
option has to be enabled before doing the scan.
http://www.cgsecurity.org/wiki/PhotoRec_Step_By_Step
If you use the brute force option be prepared for it to take days to
analyze the partition.
