What is the expected life of a 3.5″ HD or a DD diskette?
The life expectancy of a 3.5″ HD or a DD diskette is highly dependent on how the diskette is stored. Under controlled temperatures, humidity and dust conditions the diskette should last forever. Storing data on a diskette for five years in an area where temperatures are fairly constant (60 to 80 degrees F.), humidity that is controlled and diskette being stored in a storage box so dust doesn’t collect on them should not be a problem. Follow best practice in terms of backing up your valuable data on diskettes.
