Best method to encrypt an external drive
It seems there are two basics methods to encrypt an external drive from macOS:
1) Using Disk Utility: https://support.apple.com/guide/disk-utility/encrypt-protect-a-storage-device-password-dskutl35612/mac
2) Directly from Finder: https://support.apple.com/guide/mac-help/protect-your-mac-information-with-encryption-mh40593/mac
Why would anyone ever choose option 1 if option 2 doesn't erase existing data? Are there benefits to going with option 1?
