Reading older CDs

Does anybody else have problems reading older Data CD/DVDs? I can only read them booting from High Siera (which I had to put on an external Hard Drive and run from there). It is really frustrating. My current system software can see them with their names only in Disk Utility (and they must be unmounted from there). I have 400 CD/DVDs that I used in the past to save work. I can read about 250 of them, but some important stuff is on the older ones. I have them all catalogued, so I know what is there it just takes an enormous amount of time to retrieve it.

Images, PDFs, Tifs, Documents. It is not that they are Disk Images. They are the real thing. As I said, I can read them in High Sierra. On my MacBook Pro running Catalina with Disk Utility the names are visible as is the fact that they have an amount of space taken up on them. I just can't read any of the files or actually see the disk on my desktop.
