Good thought, but anything short of "dd if=3D/dev/<tmpdevices> of=3D/path/to/some/location" probably won't preserve the corrupt bits. Think of dump as a version of tar that also knows how to read file systems directly. It only preserves files and their contents not the actual file system bits on the disk -- Brooks --dDRMvlgZJXvWKvBx Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQFFNVpOXY6L6fI4GtQRAk93AKCMYFEHt7OsKqCw1AhkvZdBJ9pkWACguW+5 QhIyPtHoaeP0Ffn/HYFZcD8= =Ee7+ -----END PGP SIGNATURE----- --dDRMvlgZJXvWKvBx--
