In the early days of this list (think back 25 years), I believe it was Tim Shoppa that was recommending either Gold CD-R blanks, or Verbatim DataLifePlus. If I remember correctly, he’d done some aging tests on them, and they were the two that held up well. As a result, I standardized on Verbatim DataLifePlus for any CD’s I expected to be reading after a year. I’ve read ones from 1997 without problem. In fact I think I’ve only had a couple minor issues. One of the disks I read had to be washed before I could even attempt it as it has been sitting out bare. What has surprised me is the results from the floppies, mostly stored in the garage for the last 15 years, and before that, I don’t remember. Granted I tended to go with higher quality floppies, but still, I’ve expected a lot more issues than I’ve had. Some of the 3.5” floppies I’ve read date back to 1987 or 88. Mind you I’ve not tried to recover data from 5.25” floppies yet, I’m still trying to find those, and a big drawer/box of 3.5” floppies. Zane
