Or if you’d like the files on your drive encrypted. You can pick APFS (Encrypted). You’ll be prompted to enter in a password.
Whatever you do don’t forget that password or you’ll lose access to all your files.
There are two other APFS options.
APFS (case-sensitive). This is where your Mac OS X treats a file called photo and Photos as two separate files. Normally Mac OS ignores case.

About Simon Irons
As an admin I spend my day helping folks with their Mac issues. From the guy at work, through to unofficial 911 support for family and friends. I swear they have me on speed dial.
For fun I like testing out and playing with new stuff. I think Apple make the best products on the planet.
In my spare time I like to fish and play around with boats.
Thank you! Thank you! Thank you! I attempted to use the provided Mac software that came with the T7 Shield, and transfer my 1.23 T iPhoto folder to it, the transfer was going slow and went from 8 hours to 2 days in it’s estimate for completion. I found your article and reformatted by every step for AFPS and, wow, now it says under an hour for the transfer.
Thank you Gregory, I’m glad you took the time to follow the steps and got the result you needed. Just remember to have a backup of the Samsung external drive and your iPhoto folder. I’ve found the Samsung drive really reliable, even so it never pays to have your important information stored in the one place. 🙂 Always have a backup plan.
