Did they require the failed drives to be returned? Did the secure erase function work on a failed drive? I guess this is a good reason for full disk encryption even on machines where I'm satisfied with their physical security.

Yes, they sent a prepaid label to return the bad drives. I did a secure erase both via Linux command line and via their proprietary software and it seemed to work. The whole process took about 3 weeks per drive.
