    "Could not open scratch file because disc is not available" Mac

    DaleH Community Member

      I recently changed the Photoshop (CS6) Scratch Disk choice from the default Boot Drive to one of the other internal drives in my MacPro (OS 10.6.8).

       

      When I restart Photoshop (CS6) I get the message:

      "Could not open scratch file because disc is not available"

      and Photoshop will not launch.

       

      I then restart Photoshop with "Command - alt - shift" keys held down

      (as per suggestion at <http://forums.adobe.com/message/3937003>)

      and reset the preferences which allows Photoshop to come back.

      (Resetting preferences returned the Boot Drive to scratch disk status.)

       

      I have another MacPro that - same OS 10.6.8 and Adobe CS6 - and I don't have this scratch disk allocation problem.

       

      What is going on with the one  MacPro that prevents me from selecting a Photoshop scratch disk other than the boot drive?
