this program is untested
(i don't have a Puppy cd to test it)
I have 2 copies of 1.0.5rc1 (one burned with WindowsXP, and one burned with Gcombust). Both copies checked by your tester program came back "ok".
I guess that means your program works...

great ... thanks for the feedback
if it says it's ok, it almost certainly is ok
it checks the md5sum of the cd, and if even 1 byte is different from the iso, the md5sum won't match
if it's says it's not ok, it might still be ok
it might be a relatively unimportant byte that's wrong
or it might not read well on that drive but it will read ok on other drives
the program just does something like this:
md5sum /dev/hdc
which actually works sometimes
but sometimes there are problems with the read-ahead bug or with padding characters, so it's safer to use dd to read the exact number of bytes from the cd
