How to encrypt an external drive without deleting the drive before?
I like to encrypt my external USB drive, which is formatted as "MacOS extended journaled".
When I choose the command "encrypt" and enter a password I get the result:
"A GUID Partition Table (GPT) partitioning scheme is required"
I have no possibility to park my data elsewhere to delete/repartition my drive.
How can I solve the problem please?
Because I'm curious: Is that a bug in macOS?
If so: Can one expect that the problem will not persist, when a new file system APFS will be introduced in macOS High Sierra at the end of the year?
Thanks.
