newdisk —
Prepare a new disk to be usable for X680x0
  
    | newdisk | [ -vnfcp] [-mmboot] raw_device | 
newdisk prepares a new hard disk to be bootable from by
  X680x0. It should NOT be used for floppy disks.
It creates a disk mark for IOCS to determine the disk geometry,
    writes the primary boot program (mboot), and creates empty partition table.
    The option are as follows:
  - -v
- Verbose mode.
- -n
- Dryrun mode. Nothing is written to the disk.
- -f
- Force. Usually, when newdiskdetects existing disk
      mark, it aborts with some error messages.-foption prevents this behaviour.
- -c
- Check only. newdisklooks at the disk whether it
      is already marked.
- -p
- Do not create the partition table.
- -mmboot
- Specifies the mboot program to be written.
  - /usr/mdec/mboot
- The default primary boot program.
Thenewdisk utility first appeared in
  NetBSD 1.5.
