Have you tried a Linux Live CD, to see whether or not it can read the disk? I had a drive that FreeBSD choked on trying to mount, yet a Linux Live CD was able to boot and read from the UFS filesystem fine (presumably it only implements the bare essentials to be able to read the UFS filesystem, and perhaps omitted some of the other sanity checks.. It sounds like it would be at least worth while trying... Cheers Antony
