FM-Towns (Marty) Backup procedure?

Can anyone offer some input to properly make images of original Towns or Marty games? CDRWIN(recent and 3.9H), A120, CCD, etc… have all unsuccessfully attempted backing up the original discs. Most recently CDRWIN 3.9H gave me “Error: Unable to analyze disc layout. Illegal track type encountered.” Any help is welcome.

No dice? Last attempt.
