Can I rename my fast drive after moving things to it?
Short answer: Better not. Shortcuts on your Mac reach moved items by their location on the drive, which includes its name. If you renamed it and things stopped opening, rename it back and reconnect.
It's best not to. The shortcuts left on your Mac lead to your moved items by their location on the drive, and a drive's name is part of that location in macOS. Renaming the drive can leave those shortcuts pointing at a name that no longer exists, so moved apps and folders won't open.
If you've already renamed it and things stopped opening, rename it back to its original name in Finder and click Remount fast drive or reconnect it. If you want a differently named drive, set it up as a new drive with Transfer Drive instead.
