That looks pretty normal. Did you try doing an: fdisk -I ad4 or maybe fdisk -BI ad4 It takes that to get fdisk to initialize the disk. (the -B puts the master boot block there. Just doing an fdisk ad4 only had fdisk read out stuff and there isn't anything there yet to read - so of course it is invalid. ////jerry > > Geometry output: > > Geom name: ad4 > Providers: > 1.
