There are two types of hard drive, ones that have failed & ones that will fail. This includes all types of media, whether Magnetic, Optical or Solid state. If you have only one copy of something, you don’t have a back-up, if you have a second copy you don’t have a back up plan. If it is valuable or important to you, you need several copies. Facebook is not a suitable place to use as image storage, nor is wordpress. You can have a back up on-line, but use something that is designed for data storage. You need to have at least two copies plus one off-site.
Anyway my point is I have had to dispose of a hard drive today that failed, not a cause for concern as everything is backed up multiple times in several locations, so new disk installed into the system and data restored to it.
