Anybody heard of LifeSaver?

[maxwell@acsu.buffalo.edu (John H. Maxwell)]

Hello netters,
   I have been scrounging around in a few boxes and ran across a super
disk utility that has saved my hide several times. The program can
literally resurrect an otherwise defunct diskette, ie. many bad tracks
or sectors. Doesn't matter what type (DOS 3.3, ProDOS, Pascal, CP/M),
although it does its best on DOS 3.3 with reconstructing track/sector
tables and entries, other formats are just read and re-written track-
by-track.
   My question is this: It is very old (Copyright (c) 1983) and I was
wondering if anybody knows of/has heard of/has a faint recollection/knows
the authors/knows of an updated version of this program. The only info
on the title screen is the authors with no address, phone number, etc.

    The authors are: Donald Lee and John Worthington.

    The program version is: Version 2.0

    That is the extent of the info from the title screen. I am interested
in getting a copy of the latest version (if there is one) and would like
to congratulate the authors on a well written and *very* useful program.

    Any help from the collective net would be greatly appreciated.

      Cheers,
        John Maxwell       maxwell@acsu.buffalo.edu
