Drive keeps 'unsharing'
 

I have a shared USB drive. I backup that drive using SuperDuper! and it keeps unsharing the drive.

Drive is plugged into my Mac. Shared over network. Drive backed up w/ SD. "shared folder" keeps unchecking.

Anyone seen this?

I can't think of anything that we might be doing that would unshare the source drive. We never write to it. We refresh the list of drives and make sure ownership is on... but neither of those should affect its share state.
