I worked for a startup ten years ago that stored a lot of user data. A batch of drives from the manufacturer had some sort of firmware issue. It affected a lot of users. Essentially their data was put into read only mode by our service. Two weeks went by before the manufacturer came out and worked on replacing the drives and migrating the data over for us. Unfortunately the data center admin at the time didn’t have backup servers and drives in place and lost his job over the snafu once the drives were replaced. Always have backups of your data and make sure the drives are good quality.
