Hi Amanda,

It sounds like either your hard drive is currently performing some other task or you've run out of space on your hard drive.  In the former case, you can monitor this via your system tools and in the later, simply make sure you have enough free space left on your drive.

Thanks,
David

What OS version are you using?
What version of Photoshop are you using?

Disk Unavailable could be caused by a bad connection to an external disk or a network file server.

I have a Mac, OSX Version 10.9.5. Photoshop CC 2015. I finally ended up being able to save the Photoshop files to a jump drive, then I restarted my computer and the problem disappeared.

I do suspect not having enough free space is an issue. I am a photographer so I have lots of files. I usually only have about 10% free space on my hard drive. I move most files off to external storage, but I cannot seem to open up enough free space. I have 250 GB storage on my Mac. Currently 90 GB is photos, 43 GB is Backups and 68 GB is "Other". I've already moved Lightroom backups to external storage. Any other suggestions as to what common culprits in the "Backups" or "Other" categories are taking up all the space? (I don't have any movies or music on this computer.)

HI Amanda,

I'm sorry.  I don't have a recommendation for other files to move.  But, looking at your system specs, yup, I agree, the issue was almost certainly lack of scratch disk space.

Have you thought about moving your photos to external storage too?  That might free up a LOT of room...

Thanks,
David
