I've never paid any attention to these warnings. At one point I even
recycled about forty old Lisa Workshop distribution disks. Most of them
formatted and worked ok.

I find that perhaps one disk in ten just won't format. So I guess the
formatting routines do a fair amount of checking. Anyway I either toss these
ones or use them single sided.

For disks that will see a fair amount of use, I at least try and start with
a new disk (SS). For backup I just recycle whatever is around, using new
ones if I don't have any old ones.

The bottom line is the Mac software does seem to be pretty good at finding
bad spots either during formatting or when writing. So far (touch wood) I
havn't had any problems. (And I was about the second person to get an
external double sided drive for my Mac 512k in Vancouver :-). Of course now
that I have a hard disk I very rarely use floppies for anything other than
backup.
