If you're willing to lose the data on the disk - or have no data on it - you can use "disklabel -w -r /dev/da0 auto to put a label on da0. You then need to do "sh MAKEDEV da0h" to create the partitions on the disk (no slices at all). If you want to use MS-style slices, use fdisk first, then use disklabel on /dev/da0s#, for # being 1, 2, 3, or 4. <mike > Mike Meyer wrote: > > > greg simonoff <gsimonoff@geocities.com> types: > > > I',m trying to mount a SunOS/external drive onto a FreeBSD system > > > using a 50 pin cable.
