At least 7.1 will do this. I have a couple baddish floppies I format in my Classic that do this. It'll slowly run through verifying, and the available capacity number will slowly drop until it either finishes, or hits a threshold and fails out. It appears to be right around 1 meg on a 1.44 meg floppy that it dies.
