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.
