I'll add that to the man page but as far as I could tell this would seem
to be a violation of the Mandatory command set. If the drive enters a
Degraded Mode of operation as a result of an improper Format command
(for that device), the standard recovery is to issue a proper Format
command. At least that's what all the documentation I read seemed to
say, and the Degraded Mode drives I had on hand did recover when I did
this. Anyway, the code I added doesn't specify this information in the
Format command unless the user provides a blocksize parameter.
