Hi carrotop838,

If you're trying to erase the internal drive inside your Mac, that will fail unless you're booted into macOS Recovery. For safety reasons, you cannot erase the disk containing the macOS that you're currently running.

If you're trying to erase a different drive or disk, or if the error is appearing while you're in macOS Recovery, please let me know.
