How is the system supposed to know that a once-broken drive is now
not broken? You can have other failures beside disconnecting.   Or
which, if any, of your running partitions should overwrite the data on
a freshly added disk that might already contain needed data?  You can
pre-configure spare devices if you want them to automatically replace
failed ones but otherwise the system shouldn't do potentially destructive
changes by itself.
