[Coco] Reading floppies with CRC error?

[Kandur]

Nick, you are talking about 'now' and the 'future',
I agree with you 100%, but my probem is from the 'past'.
In the good old days of the Coco-3's birth year, we had no
SD memory cards, or DVDs, cheap HDs were were just a dream.
We used, what we had, floppies. Interestingly, 24 out of 28
floppies remained in excellent conditions, two had signs of wear
and only one was bad. My guess is, that that one was an 
overused, worn out floppy when I made the archive. 
Shouldn't have used it, my fault.
Anyway, I used to have a program, that rescued bad floppies.
It just kept reading everything non stop, garbage and all.
Later I had one like this to read bad CDs.
This diskette had some Sculptor database and 
procedure files of my music collections' catalogs. 
Not terribly important, just somehow don't feel like 
writing the missing procedure sources again.
