Assuming that only the volume header was lost (as opposed to the volume contents) you may be able to reconstruct the volume. The critical info, the actual BL headers, isn't stored at the start of the partition. However, the offsets of those BL headers (they are replicated a few times) are stored in the volume header. You'll need to find them again in order to reconstruct the header. Fortunately, they start with a distinctive "magic number" - the string -FVE-FS- that you can scan the partition for. You can try resurrecting your volume using the on-disk structure layout described here: Note that it's incomplete, so you may need to cross-reference with other BL drives to figure out the expected values. I was able to repair a damaged BL volume, with the help of this information, using a hex editor in a Linux LiveCD.
