Hello, 

My scratch disks are full and I keep bailing out all unnecessary files off my computer library but the notice keeps coming back! I want to use my external hard drive as my scratch disk instead of my computer's hard drive but it doesn't come up as an option when I go into Preferences to change my scratch disk. I've looked into this issue and it seems like I have to re-format my external hard drive to a weird format to make it a valid option that the computer recognizes. Is this a thing? (I'm on a Mac). Please help! I'm doing graphic design for a company and this is so frustrating!

Basically you must format your external drive as macos and that erases anything on it. So move any files you want to keep off that External drive.

Photoshop will only recognize disks formatted as HFS+ or "Mac OS Extended (Journaled)

Open Disk Utility on the Mac  (Use Spotlight to access it by name)

Select the External drive you want to format

Click on the Erase button at the top and from the Format dropdown menu: "macos extended (Journaled).

When that is done, click "Erase" blue button on the bottom right to start the format. When that is done, Photoshop should list your drive as a scratch drive.

Same idea. First move any files off before you format, because this will erase them and format as NTFS for a Windows scratch disk.

 

Since I don't work with Windows, here's a picture guide how to do this:
