[cctalk] Damage to CD-R from CD Sleeve

This is a strange one. I have a bunch of CD sleeves like this, that I used to use. https://www.amazon.com/Mediaxpo-Double-sided-Refill-Sleeve-Holder/dp/B002RO… 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. Zane
