On my system, FreeBSD 5.0-CURRENT #1: Mon Nov 4 21:00:50 CET 2002=20
fdisk ceased to work after a recent upgrade.
It used to work fine under GEOMized kernel
with both internal ATA disks and external IDE drive
attached via fireware or USB (tested both).
I had to switch to non-GEOM kernel (my disklabels
give my warnings), updated everything, and fdisk
ceased to work.
I reverted fdisk.c to 1.64 (used to be 1.66)
and now fdisk works fine again (with a non-GEOM kernel).
Disk layouts below.
Another question, can I "geomize" existing disk?
I keep getting disklabel warnings about mismatched
partitions and slices.
