Yev from Backblaze here -> Not sure it would have fixed your particular issue, but we recently introduced a new client that fixes a few outstanding issues with the way external drives were being handled - it sounds like it might have helped in your case. I'm sorry you had a bad experience with support, if you can post your ticket number, I'll take a look at it and make sure that the head of support sees it so they can do training on it if necessary.
