recovery service can do it.



In case you're not aware of it, such a service is *very* expensive. Be
prepared to pay well over $1000

Wasn't there a piece of software - it either ran under DOS or included
the OS, I think it was bootable in itself - that would repeatedly read
until it got something (possibly taking days to do a disc)? I think it
cost about 50 pounds. (I vaguely remember the name Spinrite, but that
might be something else entirely.)

I don't know if it works at all with modern (even as old as is being
considered here) discs that have remapping firmware.
