Coverting old DC releases to selfboot problem...

[J!]

Hi guys, I was trying to use bin2boot to make my old dc copies to selfboot (e.g. Kalisto's releases)
But after it sucessfully converted to a .cdi, I used CDMage to ##### if the image is corrupted (just in case), and the result from CDMage says there are errors within the image, therefore, I am afraid to burn it cuz I don't want to make any coasters...so is this normal or what? Please let me know, so I can ####t burning, thanks!
