逆に言えば、もし fdisk が使えるなら、それを使う方が簡単かも知れません。

# mfdisk -h

Partition table manipulator for BUFFALO INC. Link Station series. ver 1.5, 2003.10.3

Usage: mfdisk DISK     Create partition tables for HD-LAN ver 1.xx
       mfdisk -f DISK  Create partition tables for HD-LAN ver 2.xx
       mfdisk -h DISK  Create partition tables for HD-HLAN
       mfdisk -g [1:2:3:5:10:20:50] DISK  Create partition tables
       mfdisk -a DISK  Create partition table for HD-HLAN's USB Disk
       mfdisk -c DISK  Create partition table(s) with menu
       mfdisk -p DISK  Check partition table(s)
       mfdisk -e DISK  Deleate all partition tables
       mfdisk -d [1:2:3:4] DISK  Create partition tables for Link Station
Here DISK is something like /dev/hda or /dev/sda

# mfdisk -c /dev/hda

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
