I've actually had good luck with old used bonus disks. I acquired over a thousand 3m disks still sealed over a year ago (have about 500 of those left) and of the ones I've used they average 1 bad disk right out of the shrink wrap per every 2 boxes of ten.

Verbatim disks I have had the lowest failure rate. Ultra magnetics were the highest failure rate.

I actually had over 500 disks in storage from my bbs days in the 80s. My ae line went offline the end of the 80s and that's when that stuff went into storage. Pulled them back out late 2013 when I got back into using my apple IIs and A good chunk were ultra magnetics because back in the day they were dirt cheap. Well, I got what I paid for!! 90% failure rate on those. Had about 5 verbatim disks fail after 30 years (had over 150 of them) and only a small fraction of elephant disks fail.

For what that's worth to the conversation.
