Re: Corrupted disk labels

    Just a reminder:  If you have more than one Symbolics that use the same
    disk types, you can often mount the problem disk as, say, the second
    disk on a running Symbolics.

    If the failed disk only has worlds that you can rebuild or copy from
    somewhere else, you may just want to reformat, (if you might turn off
    the machine or didn't SCAN the disk flods, you should have the
    breath-of-life tape handy), rebuild the initial file system (which
    specifies where the bad blocks are) from the tape for that disk drive,
    load a world onto the machine, and go on from there.

    If the disk had LMFS files that you can't easily recover, you probably
    do want to try to recover without reformatting by swapping the disk
    to another machine (by cross-connecting the cables and all the other
    details (like unit select numbers)).
If you need to recover files from a partially broken LMFS, I have a prototype
tool that I'd be glad to supply.
