Did you run a RebuidBS?
Your length of your partition and info about the length of your partition in your boot sector are slightly different.
Info: size boot_sector 2930277042, partition 2930288067
In case, can you run a RebuildBS and copy and paste the content of your log file again?

Ok, I'm working on RebuildBS. Is that supposed to take a while? I've been looking at the attached screen for several minutes. Here's the log so far with the RebuildBS in process...

any data; even if the partition is not bootable.

Yes somtetimes it takes a bit longer.
Please finish it, and copy your log and a screen shot of your result after RebuildBS would be appreciated too.

Fiona - I'm a little concerned as I'm still looking at the same screen and it has been hours later. Can I close it out and start over? It isn't responding to any key commands (the computer is, just not testdisk).

If it hangs, you should stop it!
Often due to a faulty file system?
In case, you should copy/backup your data.
