I have many degraded CDs from 1998-2010. In 2019 almost all of them would read, eventually, even as metal flakes came off the disks. I recovered most data from most. My CD-Rs were a mix of brands, nothing special or expensive. But my CD-drives are old too, from 2006(?) or so. I wonder if like with floppy disks and drives, modern CD drives are less capable than old ones because they're no longer a premium product?

When I ripped CDs I had from the 00s in 2019, I used an external Blu-ray drive from probably 2018 or so. Seemed to work okay; see [0]. I didn't have access to anything older so I can't compare but I think both new and old drives are probably good.

- robocat 5y agoThanks. I anti-corrected it to red from blue when I found the video, and the statement felt really wrong when I wrote it, but I thought fuck-it - the video link is too good to miss! Lazy me.
- girishso 5y agoHow did you recover the data from CD/DVDs? I checked at a local shop they are not interested in recovering CDs.
