Ran FixUDF first. It couldn't copy any files.
Then I ran Isobuster 1.5. It spent at least 10 times as much
time scanning the disk and was
able to copy 86 files to the hard drive. In one directory on
the CD (50 files) it was able to read the filenames.
In the other directory (36 files), it had to generate names
such as "Recovered File 0.mp3".
Conclusion: Isobuster is King.
Long live the King!
