# Why does Storage Studio say it couldn't unlock Delta Drive on this Mac?

Storage Studio keeps what it needs to open Delta Drive on this Mac. That's no longer readable here — for example after moving to a new Mac or restoring this one from a backup. Your files are safe.

Enter your recovery kit to reconnect this Mac. Once it's accepted, Delta Drive opens as before.
