Hmmm.    I don't know all the disk codes and messages, but my practice
is to be really nervous about disks and data and any time new error
messages show up, just replace the disk.  They are so much cheaper
than the data that might get lost.

Hopefully someone else can give you specific information, but
that is my general perspective.
