Just to check, this is nothing to do with Box Backup, is it?

Yes (although it sounds more like you'll have to move that directory  
away rather than deleting it all). As long as you use bbstoreaccounts  
to check and fix the store account afterwards.

Isn't RAID and journalling supposed to prevent this kind of problem?  
Has fsck helped?
