Image form is the best solution, while simply archiving the files via StuffIt or Binhex would be the 2nd best solution. Problem is I don't think those programs will ignore errors, either. It will try it and see.

Interestingly enough, there were three disks which gave errors, but after 10 minutes and some warming up (temperature really affects floppy disks) I was able to successfully image them. I'm hoping these last two disks will also work like that.
