DiskCopy
From 68kMLA Wiki
DiskCopy 4.2 is the ideal utility for imaging 400K, 800K, and 1.4MB Macintosh floppies. It's also useful for Lisa and Apple II floppies. This is because it stores "unused" data and tags, which most other utilities don't. Disk Copy 6.3.3 should only be used for imaging hard drives, but even then it often doesn't copy unallocated blocks.
