For example, say you burned a CD-R for a game console development kit, but Windows can’t read it. Sometimes, a CD-R or DVD-R might be from a platform you don’t use anymore, and you might not be able to read it properly. Name the folder something that will identify its contents, such as “CD-R – Photos from Tom’s 2002 Wedding.” Option 2: Create Disk Images For example, you could create a separate folder for the contents of each disc. It’s best to do this with some kind of organizational structure if you’re backing up a lot of discs. To do this, just place the CD- or DVD-R in the optical media drive, and then open it on your computer.
BURN FOR MAC OS RATING PC
If your PC or Mac recognizes the data on your CD- and DVD-Rs, the easiest way to back it up is to just manually copy the files over to your hard drive or SSD. Unfortunately, the 100-year-minimum lifespan estimate only applies to expensive, high-end gold-backed CD-Rs that very few people used. Like the Library of Congress report, the estimates varied wildly, from between five and 100 years, depending on disc composition. In 2010, the Canadian Conservation Institute published a detailed analysis of CD-R and DVD-R longevity that broke down estimated lifespans based on the dye and reflective layer composition. However, it depends on the quality of the disc, the type of dye used, the speed at which they were recorded, and how they were stored. From our anecdotal experience, if you have a batch of 30 vintage consumer-grade CD-Rs, you might expect a few of them to be unreadable. So, if you store your CD- or DVD-Rs in a hot attic, you might find a higher portion of them have gone bad. However, it also stated that “discs exposed to more severe conditions of temperature and humidity would be expected to experience a shorter life.”
The study concluded that most recordable discs stored in ideal conditions would last at least 30 years, but the results varied wildly by brand. It simulated the aging of CD- and DVD-Rs stored in perfect environmental conditions (that is, a room temperature of 50 percent humidity with no sunlight, and no rough handling). Library of Congress sponsored a study that estimated the shelf life of recordable discs available at that time.
Estimates on the lifespan of CD- and DVD-Rs vary wildly, from between two and 100 years.
