As far as I remember that's a backwards compatability thing from changes that were made somewhere around the FreeBSD-3.x timeframe. You probably want /dev/ad1s1e =20 > How do I 'start over'?

Old hacky trick is to zero out the first few blocks of the drive, so that fdisk(8) thinks the disk is completely virgin: # dd if=3D/dev/zero of=3D/dev/ad1 bs=3D512 count=3D10 Note that this will completely trash anything already on the drive. Then use fdisk(8), disklabel(8)/bsdlabel(8), newfs(8) to create filesystems.
