OK, I tried it.

It's the same problem. The old hard drive is detected as the secondary
slave by the BIOS, but I still get "invalid partition" when booting.

It's very frustrating. How can adding another drive make FreeBSD
detect none of the drives?

Before I tried putting the old drive on CD-ROM drive cable, I also
entered fixit mode from the LiveFS CD and ran "fdisk -B /dev/ad1"
(when only the old slave/drive was connected). It didn't make any
difference. What I really wanted to try was to remove the MBR
completely from the old slave/drive ...

Is there anything I can check/alter on the disks so I can use them 
at the same time ... Seperately the looked OK - the output from
fdisk and disklabel looked sane.

Regards,
Hans
