I added a 500GB Samsung T5 SSD USB3.0 to my iMac (OS X 10.11.6) running PS CC 2018. It mounts on my desktop, but PS fails to recognizant in the possible scratch disc options.

How do I use ut as a scratch disc?

Is it appearing as a mounted volume in Finder? I have had some strange behaviours in PS and LR with external USB disks which seem to be resolved by forcing them to be mounted in my login script.

Only other thing I can think of would be the disk format, but I haven't experienced any issues with Mac file system-formatted external disks as long as they appear in Finder.

Greg,

If you look at the bottom of this thread :

https://feedback.photoshop.com/photoshop_family/topics/photoshop-cc2014-cant-see-all-available-disks...

there is a note about configuring the system to ignore Ownership on the volume, which has resolved the issue with an SSD for someone else - may help you.

Thank you for all your replies.  I solved this:

The Samsung Drive came with an installer package for Windows, Mac, and Android that included a driver. I'm not sure how it formatted the drive. It appeared in FINDER and acted like a HD as far as the system is concerned. When I did a Get Info, "Sharing and Permissions were empty, and I could not Ignore Ownership - the box was missing.

I erased and re-formatted using Mac OS X Extended (Journaled) and PS now recognizes it.
