 Multiple problems here.
 
 - Did you intend to format a 720KB floppy? man 4 sparc/fd says:
      Bits [0-3] of the minor device number of the special files referring to
      this device encode the floppy density as follows:
            0       3.5'' 1.44MB floppy diskettes.
            1       3.5'' 720KB floppy diskettes.
 
 - eject(1) did not properly support floppy drives -- it normally opens
   special file that corresponds to raw partition of a disk, but again,
   fd(4) uses partition letters differently.  This has been fixed, see
   PR#27066.
 
 - There appears to be a regression in fd(4) -- in 1.6.2-R formatting works,
   in 3.0-R it panics the machine (SPARCstation-5):
 
 # fdformat
 Ready to format /dev/rfd0a with 80 cylinders, 2 tracks, 18 sectors of 512 bytes
 (1440 KB) Yes/no [y]?
