Tonight we replaced the defective drive and added a third drive to the spool. This was necessarily a slow process because it takes a long time to format 9gb drives and create a 27gb partition. But it's done. I saved the articles in Lobby and re-posted them, but that means all of the messages you read in lobby are new. But I figured that was better than having them all gone and losing the context of various conversations taking place. With any luck, hopefully we won't have to wipe the spool again for a while.
