Here is a short and precise instruction how to resolve such an issue:

Basically you'll have to use the "format" command and subsequently its "backup" and "label" subcommands.

Good luck!

If "format" replies with "disk formatted" after you entered its number you should be able to proceed.

Don't use the "label" subcommand (contrary to the suggestion in the first article I posted, rather follow the second one in your case).

If the "backup" subcommand returns "Restoring primary label." without any error your disk should be fine again.
Quit "format" then, don't perform any further subcommand except for maybe "verify").
