God, it hurts to see that CD. I remember when I was a kid, I had PS1 games that my uncle recorded into CDs and some of the time they would get spots all over.
One of my current DVD-RW discs (for live CDs) has disc rot on the edges. It’s the only one with the issue. I wonder what really causes it, aside from humidity in the ambient.
Aside from drives, the rest of the components are fine. But honestly, I use what I had for a computer before upgrading to my current one. Old components you have around can be a good idea.
I don’t really like buying drives second-hand, but I suppose it shouldn’t be an issue if the drive is relatively new and has had little use.
