Bad floppy disk question

[Unknown_K]

Recently I got in a few old 68K software titles and when using diskcopy to archive them one disk is bad. What I wanted to know is what is the mechanism where mac OS decides the disk is unformatted and responds with the do you want to format this disk responce? Does Mac OS try to read a specific block/sector and if it is damaged or blank asumes the disk is blank (like FAT in DOS)? Any utilities out there that can recover a bad floppy?

Of the 3 software packages only 1 disk is bad, Adobe Dimensions 1.0 Disk 1.

of course, if the file system header or table is corrupt it might think it's been unformatted. Especially if it's a file system other than what the mac uses (FAT or HFS)

I suppose you could try to run Norton Utilities on it, but that may/may not work. I would try that and see, but if the system can't read the disk, is there a way to ignore it? If you can, try that.
