It finally happened, I lost about 2.3TB of data on one of my 3TB drives to mechanical failure. Clicking and head scratching on the platters. It was half my TV Show collection I have accumulated in the past decade. I always told myself I would never waste money backing up media such as TV Show files but now that I have lost so much I am regretting my decision. It's been years since I lost a drive to mechanical failure, the last one was at least 6+ years ago but that was a 300GB drive so the loss was not as great as this. From now on I'll buy 2x the storage I need and have all my media drives in a RAID1. Important files will also have its own incremental backups in addition to being on a RAID1 drive.
