A note about old disc media that you might find valuable: there's a linux tool called "setcd" you can use to adjust the spin speed of your CDRom drive.

This is useful if you're recovering data from dodgy old discs; sometimes they become brittle over time and will burst at high rotation speeds. If you're using ten or twenty year old media, use "setcd -x 1" to dial the device down to as slow as it will go, then take an .iso image of the disk, loopmount it and work from that.

@mhoye any idea what drive to buy before trying to archive, or tossing, the CDs?
@RichiH Backblaze publishes fleet reports of drive failures every year, and my approach is pretty simple, it’s “buy two of whatever Backblaze says will live the longest that’s still for sale”.
@mhoye @RichiH Or you can just do what I do and archive to B2 with something like restic
@mhoye yes, that's what I do for HDDs as well. I meant optical drives -- it seems impossible to get reliable info...
@RichiH Yeah, that entire space has been commodified into quasi-irrelevance now. "Use an internal drive in an old computer" is pretty much the entirety of my thought process there.
