I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Photoshop forum so that proper help can be offered.

Are you saving to an external drive that is not connected?

It is connected and I was able to save on my old computer, now unless the picture is on the desktop (oringial) it won't let me save it to the hard drive.

Same thing. And unless the picture (original raw) is on the desktop, I can't save it.
