Try: http://www.watson.org/~robert/scan_ffs_freebsd4.tgz This is an adaptation of the OpenBSD scan_ffs(8) tool, which searches for superblocks and reconstructs a disk label from the results. It's not perfect, but actually works surprisingly well. It recognizes only UFS1 file systems, but could do UFS2 with fairly trivial changes.
