[Offer] MicroFocus COBOL v3.1.31
I just finished imaging my stack of MicroFocus COBOL Products disks if anyone is interested. There is a disk for the v1.3.41 update (The "Early Release" component) that I couldn't read, but all of the v1.3.31 disks seem to be just fine.

Don't forget to clean floppy drive heads. (At least run some known good disk through the drive to verify it is still reading properly and not ripping things up).
After all that, reading may still need a few retries but should not make noises or further rip things up.
"Can't read super block" sounds like you are using Linux "dd". If you have a DOS machine with a real (not USB) floppy drive available, then after cleaning, you might try Disk2img http://www.oldskool.org/pc/disk2img (Geared towards data recovery, makes one quick pass and then goes back and retries errors)
