Query: It workes very well for a few months and then died!!

I used the drive to backup all of my important files and family photos and videos. The drive worked very well for a few months and then all of a sudden decided to stop working.I only powered it on when I needed to do backups and restores so it is not like it could have overheated. I am not sure what happened.
