I was copying some files from a backup drive yesterday and after copying when I tried to open them, some of the files were corrupted. I am assuming bit rot because the drive heath is at 100%. The drive wasn’t powered on for about two years.

Luckily, the files were all compressed archives of WinRAR, it had 10% recovery record and multiple recovery volumes, so winrar was able to repair the archives, and successfully extracted all the files. If it wasn’t for winrar, I could have lost some photos or videos. I love these features of having recovery record and parity files when archiving.

What is your recent bit rot experience?
