The life of media storage that is used in modern computers has a pretty long use life, subject to error and improvements in media.
In the days when storage media actually spun in a drive, whether floppy, hard drive, etc., the chances of error increased over time, even when a low level format was used. Not every bit was salvaged and reset, because drive heads weren't perfect. They skipped, missed, etc., data on the medium. As the method has changed over to sold state storage, the possibility of error decreases.
That stated, resources are not 100% restored. As late as 2000, we could corrupt an Excel file in as little as seven copies from the original.
Before I retired, I was an IT infrastructure manager, and part of our task was to "break" PC's, storage media, etc. However, last year, I was unable to break an Excel file after 20 iterations on seven different meda (32gig thumb drives).
Progress, ain't it great!
But keep in mind, that the Magna Carta is still in existence, as are the Dead Sea Scrolls, and they can be read instantly by your eyes. The same can't be said of a deck of Hollerith cards from 1956, or a 12" tape reel from the same era.
