Well like I said, some have had these cracks for years and I have had zero problems. But....to each their own, if you feel the need to throw out any offending cracked disc then do so. I, like many others here, have never had this separation effect as a result of a cracked spindle hole. Sorry for your bad luck Frank and in the future I suggest using more care with your discs when storing them.
BTW,
why do you use such
odd spacing
in
your
posts?
