I was checking my scratch disc in PS preferences & noticed that my external hard drive which I use as my primary scratch disc is NOT showing up in the scratch disc preference section. I use one empty external hard drive as my #1 selection for scratch disc. #2, & #3 are other external hard drives. I opened up the empty hard drive to be sure it didn't crash & it did open. My question is : Why does it not appear in the scratch disc section while the other drives do appear?
Thanks
If you are going to assign a external scratch drive in Photoshop Mac, it must be formatted as Mac OS Extended (Journaled) or it will not show up in the Photoshop Scratch drive list, even if it is showing up in the Finder or Desktop. If it's already MacOS Extended, run Disk Utility First Aid on it.

One thing worth double checking is whether you can create a file on that partition. It might be that Photoshop hides read-only areas.

I was really hoping this "saving a file from PS to the drive in question" solution would work, but no dice, so far.
Windows 10. Photoshop CC, latest. D:// drive. NTFS. Healthy.
The only thing different from some of the above, that I have to report, is that mine is actually an *internal* drive, not external. Not that that should matter, but thought I'd mention it.
My external and main C:// drive show up properly in Scratch Disk list.

I've had the same issue and have tried all of the above - did you find a solution?

Not sure if you're having the same problem but mine wasn't working because I was using a 2.0 external hard drive, i ended up buying a new one which is 3.0 and it worked perfectly.

I had save a Photoshop file from within Photoshop onto the external drive first, then it appeared in the scratch disk list.

I was having an issue where the only drive listed was my main HDD, as soon as I tried saving a file to the drive I use as a scratch disk it became listed.

Hi! Another thread helped me out. Which is to check and see if photoshop has permissions. Posting this here for others to find. https://community.adobe.com/t5/photoshop-ecosystem-discussions/scratch-disk-not-recognized-with-phot...

My new external hard drive is a T7 Samsung Portable SSD - it formatted to Mac automatically. I don't see a way to change the format to "OS Extended" or Journaled as stated in a correct answer. Can someone please advise?

Driving me crazy for days - For me, (Windows server 2019 on AWS), I had attached a new Volume to my EC2 to be used as a scratch disk, but I hadn't set the permissions correctly for users (i.e., Photoshop without Admin elevation). Make sure you have read/write/modify set for your user - if you can save a .psd file to the scratch disk root from Photoshop, you're probably ok.

Hi that could help someone today because I've tried everything here and didn't work until I did this:
What did not work:
What worked:
Then it worked and Photoshop even asked me he want to have access to my external disk.
So basically I formated twice. Don't know why.
