Any good software for repairing damaged Jpeg files?

[Robbie Hatley]

I've been looking for a good program which can repair damaged Jpeg files.
No, not "recover"; REPAIR. I've googled phrases such as "repair jpeg file"
and come up with over one million hits -- all of them worthless. They're
all data-recovery programs. They just return the corrupted files (with
corruption still intact) as being "recovered". Worthless garbage.

What I need is something that can repair Jpeg photos which have
one or more single-bit errors in them somewhere, causing all parts
of the image rightward and downward from the error to become
garbled, like so:

Unfortunately, quite a number of my photos have become corrupted
like that over the years, due to power spikes or cosmic rays or whatever
knocking one bit out of alignment while copying, moving, defraging, etc.
It would be nice to be able to repair these damaged files.

I did find one program which ostensibly is capable of allowing the user to
hunt-down and fix damaged bits manually. The program is called
"Repair Jpeg", by Wim Vanmaele. However, it is extremely difficult to use.
It is basically just a binary editor with a picture display. To successfully
repair a damaged Jpeg file with this program apparently requires some
pretty low-level knowlege of Jpeg compression and Jfif file formats.
I haven't actually successfully repaired a photo with it yet.

Surely something more "automated" is out there somewhere? Anyone here
know of any software that can do this?
