Oddly enough there is a specific album, live’s secret samadhi, that I’ve never found a rippable copy of. I’ve found like five copies over the past half decade at used record stores, all in seemingly perfect condition in terms of lack of scratches, but they won’t play correctly all the way through or rip correctly. Could be anecdotal bad luck, but I think the cd pressing of that album has bit rot in general for some reason. I’ve not seen that on any other factory discs I’ve ripped.

I bought a CD boxset of all the MAD Magazine issues from launch until the late 90s (when I bought it). About 8 years later I still had it and attempted to back it up into ISOs It was like 6 discs and of course disc 5 was unreadable so the entire thing was useless :-/

I’ve had one (extremely cheap) pressed DVD start to separate, but I was able to archive it before it became unreadable.

Indeed. My oldest music CD is from about 1991. Still playing it from time to time. Flawless.

i have multiple wii u discs that dont work

There was an issue with discs made by the PDO pressing plant in the UK between 89 and 93 - https://en.wikipedia.org/wiki/Compact_disc_bronzing

I’ve seen it, but I collect a lot of magazine cover discs, 90s PC games and stuff, it’s def pretty darn rare. ‘Did the previous owner(s) abuse the disc?’ is a vastly higher concern for me in my eBay adventures.
