I was working on a large document in Photoshop CS5 that ate too much of my main drive (to the point I had to quite and restart a few times to clear it out) when the main drive was set as a scratch disk. I went in to preferences and changed the scratch disk to my secondary internal drive, where I keep all my media. Then quit Photoshop to clear the cache.
When I tried to open Photoshop again I get a message at start up (haven't gotten in to the program yet) saying: "Could not open a scratch file because the disk is not available". Clicked OK. Then another warning message: "Could not initialize Photoshop because the disk is not available."
Both disks are mounted and available. Since Photoshop never actually opens up I cannot go in and reset the scratch disk to my intinital settings.
Anybody got an idea what I can do to solve this?
Worst case: trashing prefs by keeping ctrl-alt-shift pressed while starting Photoshop (and then using the dialog) should allow you to open it.
Great. Thanks. That worked. Much appreciated!
