I just got this hard drive and all of the permissions are set to read and write, but when I set my scratch disks to it when I try to start a new project in premiere, it says that it's unavailable/write protected and asks me to set my scratch disks to my documents folder. It does this for my other external hard drive as well. This one is brand new. Please help me!! I need to start editing on this computer, but I know I am going to be editing on another computer tomorrow so I need the scratch disks to be set to my external hard drive.
