I looked at the links and I figure that with the break-the-fusion, then restore-the-fusion, there would be too much con-fusion for me. Add in the fact that I have a partitioned drive, which is probably an additional wrinkle, and we'd probably be into straight-jacket territory. The two partitions now each have two CCC backups, so I'll take my chances that it may not be a bad sector issue.

Thanks for the education, though.
