    Very interesting, but ... Unless one sneaked by while I wasn't
looking, all disk recording formats use the available space on the disk
no matter where it is and except for a brand new or newly formatted
disk, the files are not always contiguous. So, tricking a disk without a
TOC to play using an unrelated TOC you'd think the playback would jump
in and out of the files instead of playing each file from start to
finish. Did this happen to you?
    Thought #2 - if it's this easy to recover a TOC, why can't Sony do it?
    Thought #3 - when the power went off on your MD, some kind of
proto-TOC had been written and all it needed was a generic procedure to
make it valid, which you did with your workaround. That leaves us with
the same question about Sony - if you could do it, why couldn't they?
