Now if a bad block is discovered on your Flash device while trying to

holes, etc. The fix is to format the card and that will replace the
directory structure. Life goes on.
formatting won't fix a bad block, the image file that is thus
"damaged" should just be deleted
Steve, I didn't say that. I said that formatting would fix a screwed-up
directory structure (and/or files) caused by their having been a bad
block in the directory structure itself. The odds of that happening are
relatively high because the directory structure is updated for very many
file operations, like opening and closing them.
Once you have a corrupted directory structure, formatting is about your
only recourse. (Well there's chkdsk /f or the Mac's Diskutil, but we
won't go there.)
