You can get a *good* md5sum.exe from here: <http://etree.org/md5com.html>
Or here:
<http://downloads.activestate.com/contrib/md5sum/Windows/>

Just remember that wherever you get it from it will be 48k in file size
and have the md5 checksum: eb574b236133e60c989c6f472f07827b

BTW, don't use the pc-tools.net md5 checksummer to get the checksum of the
48k md5sum.exe program, either. The result will not be valid.

Use something reliable, such as md5 via the Mac's Terminal app to get a
correct md5 checksum

Another good checksumming tool (for Windows) is fsum.exe (no link handy,
sorry).

fsum.exe can check (reliably) md5, sha1 and more, very useful, freeware.


I'm curious as to why you are asserting that Jem's md5sums program
is inaccurate. My (non-exhaustive) experience suggests the program
works fine. When it reported md5 results at odds with the Mac's
/sbin/md5, the installs failed. When I ftp'd a file instead of
using a Toasted "Mac & PC" data DVD, the md5sum matched and lo and
behold, the install worked. Further, when I burned to DVD-ROM
format instead of "Mac & PC", the md5's matched, although I did
not care to do an uninstall/reinstall for the ultimate test. :p
