Try booting from livefs disk and wipe the disk clean. Choose Fixit shell, and do something like if=/dev/zero of=/dev/ad0 bs=1m This helped me in the past.

IIRC I had very similar problem installing on Alpha ATA and SCSI disks. anton -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 331 5944 Fax: +44 (0)117 929 4423
