When I right-click there is no "Encrypt" option.i did this: right-click on the drive in the sidebar, and selected 'encrypt'. i did it on my archive external drive and my backup drive (used with carbon copy cloner). both usb, both formatted AFPS (when i first got them).
now, when i restart or boot my imac, i have to enter the password for each, then all runs as usual.
the process took days...
If it’s just some data and not all contents, try a disk image. Open disk utility and select File > new Image > Blank image. Fill out the wizard and choose size, encryption level and a password, etc. Save this file on the USB. Mount the image as normal whenever you want to view or add files.
are you right-clicking on the drive in the sidebar of a finder window?When I right-click there is no "Encrypt" option.
More toward "t0m3k"all my disks are APFS...
