This is fine.  I assume you only get one message like this.  It means that
the media (floppy) in the drive has changed, the old capacity info is
invalidated, and that CAM should attempt to retry the command to get the
new data.

This message is harmless in the absence of other problems.

But no problems like the drive hanging after multiple mount/umounts or
writing problems or anything?
