Good thought, but anything short of "dd if=/dev/<tmpdevices> of=/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
