The state that the file system is in. If it is corrupted then it is
unusable, if it is busy, the MIB is being updated. Floppy not present is
a state used in DOS only and means that the floppy isn't there or we
couldn't mount it. Incomplete means that we got a mount for a DOS floppy
duing boot, but because of 30 second timeouts in DOS, we are not willing
to take the hit during boot. Fill in minimal information and let Site
Manager do the 'DIR' that will fill in the rest.
