====== OpenBSD/Disk formatting ======
This is how you can format a disk on [[OpenBSD]]:
  *Use ''sysctl hw.disknames'' or ''dmesg | grep sd'' to find the names of attached disks.
  *Then, run ''disklabel -E sdX'' where X is the name of the connected disk you want to edit (MAKE **SURE** YOU HAVE IT RIGHT!)
  *Enter ''z'' to delete the existing partition table. Then type ''a'' to add a partition. Afterwards ''w'' and then ''q'' to save and quit. 
  *After this is done you will be left with a partition called sdXa. (a is the root partition in the bsd disklabel scheme) Run ''newfs sdXa'' to format it.
