    I may look into this to grab an(other) image of the "Maintenance"
disk. but I've already imaged that with plain old "dd" successfully.
My issue is with the truly dead one that's in "last erred".

    In your case, it's possible that it was an "empty" part of the file-

stitch back together and then a bunch of sort partitions contained
thereupon.  It's a mess.
