Hello there, I am trying to use my external hard drive as the scratch disc for photoshop. The external works perfectly fine with everything else on my computer and is where most of my stuff is stored and run. However, when I open up the scratch disc menu in Photoshop, only the C: drive shows up. My external is my D: drive but I can't get it to show up. I have looked and tried methods posted for similar issues with no success. If anyone was any clue to help me out in this, it would be greatly appreciated.
