"Lost" a lot of backups to a WD MyBook a while ago. The story is interesting enough to mention: first it showed up as non-formatted. Turned out the disk was encrypted and the key was stored in the enclosure which somehow lost it. After a while I found out the encryption key was stored on the disk on a predictable location and could be extracted and used to decrypt the disk, but at that point the disk had stopped answering completely. I still keep it around because someday I will probably try to get a recovery company to look at it, but I still wonder why they put that "encryption" feature there in the first place.
