Not exactly what you are asking but I recently sold off my physical CD collection of about 500, after being in my closet for the past 20 years so no temperature/climate extremes, a few of them had signficant value on EBay, but when I tried to use Exact Audio Copy to verify they still could be read, about half no longer matched the online checksums or the original CD rip I had done before putting them in storage. There were three from Denon Japan that had physically deteriorated inside the disk, I could see there was a problem from a visual inspection.
