Maybe it's a driver problem.  I don't know.  Since you said that even
fdisk wouldn't run against the volume, the problem has to be below the
file system.

Reading from the old filesystem?  Can you read or copy that file
individually?  This could be a bad sector on that file system.  This
might be unrelated to the other problems.

Let me know.
