Hi GuestToo,

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
