Continuing my reading of Dan Gookin's MS-DOS 6 pour les nuls (More DOS for Dummies ?), I've discovered in an otherwise light and funny (at least the French translation is) book about DOS a section where he mentions some commands that no one is supposed to use and particularly RECOVER. The way he talks about it and urges users to delete it, made me conclude that he had a bad experience with it.
I started with MS-DOS 6.22 so it wasn't there, I've read the Wikipedia article about it and from what I've understood that it was supposed to fix lost partitions but made the disk unbootable.
Am I right? How did it do that? And in that line, if it becomes unbootable how can someone get what was fixed?
