I was archiving / ISO'ing my CDs/DVDs last month. So many of them weren't even recognized as a disk. Many had read errors. The disks were in proper form.
Did the same for my 3.5" floppy disks. None of those had problems
It's important to mention the durability of the medium is very different when you compare writables to pressed, and there's a large variance in quality for writeables, particularly now that lots of old stock (with a history of non-favourable storage conditions) is intemixed with demand being low.
If you really value your data, use archive disks. They are costly, but they will actually reach their rated lifespan, often of 50-100 years.
You should note that if you were using Windows 10, it sometimes has problems with old CD-ROMs. If you rip the disk, it reads fine, but Windows Explorer doesn't understand the filesystem and reports the disk as a DVD-R or something
