I would be inclined to divide the disk as desired, do the MSW install in the first slice and then get a FeeBSD fixit and partition the other slice and then use dump/restore to move the FreeBSD stuff over. That way you get the best fit for the new disk, no worries about tweaking geometry and no loss of the amount the new drive is bigger than the old one. ////jerry > > -- > Christoph > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
