You can usually then mount the file via mdconfig(8). If the partition table is intact you can specify that instead of the whole disk. This can make the fiddly bit with trying to figure out exactly what part will mount under md(4). If you have an idea of how full the drive was you can save reading all of the empty blocks with bs=xxx count=xxx which may speed things up considerably. -- --
