Scratch Disks Full?
On the desktop, can you click on the scratch disk, and hit command + i to check the actual usage of the disk? or can you run the disk repair from the disk utility and check if the scratch disk is corrupted.
I keep having issues while working in Photoshop on my MacBook. It says that my startup drive is full and my scratch disks are full. I do not store anything on the computer itself-just on an external hard drive and I have no idea why my disk is full. It has gotten to where I can not work in layers at all.
