How do I fix a drive that shows "Not configured" in Services?
Short answer: No external drive is set up yet. Storage Studio still clears caches without one; to move apps and folders, plug in a drive and choose it from the More menu.
"Not configured" simply means no external drive has been set up yet. Storage Studio works without one — you can still clear caches and free space — but moving big apps and folders needs a fast external drive.
To add one, plug it in and choose your drive from the More menu (or re-run setup there). Storage Studio prepares a small folder layout on it and marks it so it can recognise it later.
