Yup. I've seen the same with many of the CD holders I bought from CompUSA.
Lots of CDs/DVDs we burned and stored were unreadable after a few years
despite never being removed. Some blame is the CD/DVD quality and holes in
the unprotected label but definitely scratches.

used to use.

I’m trying to recover data from a Verbatim DataLifePlus CD, and when I
started looking at it, I noticed that it has a cross hatch/herringbone
pattern on it.
Has anyone run across anything like this? At first I was hoping to simply
wash it, as it seemed like that might be possible. I tried to wash it
multiple times, and while it seems a little better, it’s still not clean,
and I think that it might actually be etched into the surface, due to a
chemical reaction.
Thankfully Toast 14’s “Use Data Recovery” option was able to recover the
data, and image the CD-R.
Another problem I’ve found is that you need to use a Mac running a version
of MacOS prior to 10.15 if you have HFS formatted CD’s. I bought a nice
external drive, since my DVD-RW drive in my 2010 Mac Pro died, planning to
use it on my MacBook Pro, only to discover that MacOS 12 wouldn’t read most
of my CD’s. You can’t even do a ‘dd if=/dev/disk5 of=test.iso’, as they
appear to have broken basic UNIX functionality.
