Patch for DiskSalv 3 (commercial)
Some  versions  of  DiskSalv  3 will produce
unreadable    disks    after    fix-in-place
operations  because  they write an incorrect
DOS  ID.   This  patch will fix the problem.
To  apply it, unpack the archive and execute
DSPatch  <dir>, where <dir> is the directory
that contains your DiskSalv 3 executable.
