I am running Photoshop CC on my MacBook Air with macOS Sierra. Every time I attempt to open Photoshop through any means, the following message appears: "Could not initialize Photoshop because the scratch disks are full", and Photoshop does not open. I tried clearing space from my Mac in general including several GB worth of apps and removing several cache files, but nothing seems to work. I also tried holding down the command and option keys to reveal the Scratch Disk Preferences, and it lets me select the Startup and MacIntosh HD. Again, nothing worked. Anyone know how to fix this message, and/or clear scratch disk space?

This is super late, but for anyone else who runs into this issue...Similar thing happened to me. Do you make new files by pixel size or by inches? I usually go by pixels (ex: 2500x3000 or something like that), but I apparently I had accidentally switched to inches and it would only let me max the numbers to 1000. Went back to pixels and it all worked out!
Hi all,
We're sorry for the scratch disk issue. Take a look at the following troubleshooting article which can help you to resolve the "Scratch disk is full" error: Troubleshoot scratch disk full errors in Photoshop
Please have a look and let us know if that helps.
Thanks,
Mohit

I'm actually running without backup at the moment because most of my drives are disconnected ready for moving to the new system.
Interesting disaster prevention system... I wouldn’t do that. My backup is disconnected from my workhorse.

This is completely temporary, and all but my most recent activity is backed up on the disconnected drives, but I have been expecting delivery of a new system and have only a few essential drives connected right now. I normally have all drives permanently connected, which is something I sometimes worry about as I understand ransomware encrypts all connected drives. Plus a disaster like a house fire would wipe me out. I am paranoid about opening emails that look sus, but I am sure they can get you eventually.
[EDIT] I forgot to say that I use Shadow Protect that does incremental backups every 15 minutes. You can mount the back up at any of those intervals, and you can make an image of your boot drive and boot from it via a CD or pen-drive. It's one of the better $100 I've ever spent. They also have unbelievably good support.

Hmm, yes. A backup system ideally plans for a certain range of disasters. If backups are permanently connected it protects well against
- hard drive failure
- accidental deletion or overwriting
- crazy application software
It protects poorly against
- crazy system software
- malware
- mains surge
- environmental damage (e.g. water)
It doesn't protect against
- theft
- fire
For business purposes, a system which ever left me with all backups in the same building would be unacceptable to me.

My company has a three-knot disaster prevention. We have 3 mirrored server infrastructure in 3 distant places.

I don't trust the company server, we've lost files there and changed IT provider several times because of that. They say their backup is safe - until it isn't. Besides, the server is slow and doesn't have enough storage space for my needs.
So I made my own system.
I have two similarly configured machines at work and home, both fitted with 20 TB storage space. I then use synchronization software to copy new and modified files to an external drive, and the reverse process on the target machine. I've used this system for close to ten years now without a single problem.
It does take a while to set up, because you need placeholders for every file on the external. It has to be a very large capacity drive, and it takes forever to copy over the first time. But in operation, it's very efficient. One click, let it copy the day's work, pack up the drive and go home.
This way I have three copies of every file, at least one always off-site. It has saved my butt on several occasions.

At work, I need to take my company’s IT infrastructure. For security reasons, we can’t share own infrustructures with the corporate net. But as I said: we have three mirrored server infrastructures. So when buying a new server, we do buy 3. When adding disk space, we do add 3times that. Anytime any server can take over as master.
I have at home a 2 level security system (my computer and my backup server). I would like to have a level system to be immune against fire, but that is not in reach today..

hi to all users of scratch discs 🙂
this is an old one, but may i summarize the subject for 2021, as i use scratch discs on a daily base and my RAM is full early (16GB and on another mac 64GB in the moment).
i also need a scratch disc for 4k video work with adobe premiere pro CC.
this article is a good recommendation by adobe:
(wasnt allowed to post html link:) "adobe > help > scratch disc" or "Set up scratch disks"
i just dont see, what a network drive is. ethernet? or even an external thunderbolt raid? ("dont use network drives as scratch disc", they write).
apart from that, adobe says, performance is better, if you DONT set your scratch disc..
- to the internal boot disc and work disc, where your huge photoshop files reside,
- to an USB2.0 or USB3.0 external 2.5" disc (too slow)
(so, i cannot use my fast internal macbookpro 1 TB SSD, if i want max. performance of my scratch disc)
so, what is the best option for a scratch disc with maxium performance?
in my opinion, a separate and internal SSD, which is dedicated for photoshop only, and always free. (no files on it). point.
as my macbookpro laptop has no space for a second internal SSD, i only could opt for an external thunderbolt 3 SSD or HDD raid0, which is also permanently empty (no files on it).
how large should a scratch disc be? depends on your files and work method, my files are up to 40GB per single .psb (in 16bit) and i use 24 history states: multiplied, the scratch disc should be 1-2 TB ? not sure...
what do you think? thanks for your time.

Any suggestions for how to add a scratch disk in the updated Photoshop CC 2015.5 version. All of the videos and other answers provide an earlier version, and in this version of Photoshop, they moved the scratch disk to it's own tab. I have an external drive connected to my computer, but don't see an icon or a way to check (or add) another drive.
Please help!
Thanks!

Hi
( it's "command-option" at start up on a Mac )
Bizarre, I can see all my connected external HD and partitions. ( El Capitan 10.11.6 )
Try : for First select Macintosh HD, then see if you can select your ext.HD for Second

I tried that and just updated my OS to El Capitan 10.11.6 and nothing changed.
Any other ideas? Do you think it's my external hard drive? It worked for the last version of Photoshop, but when I updated it the disks changed back.

Hi
From Finder, unmount your ext.HD and turn it Off (it it has a power switch), keep PS open. Turn On the ext.HD and mount it on your desktop (do you see it in Finder too ?). Go to PS preferences > Scratch Disks, can you see/select it ?

Hi, i am having the same problem with you.
After having discussion with the support staff of adobe, i can solved it by changing the format of our external hard drive.
if you have you external hard drive formated with FAT 32, it wont be recognized in the mac computer.
try to format your external hard drive with OX X EXTENDED (JOURNALD) format, after that you can now select that drive in the Scratch disk option.
I hope it can help you.

Thank you so much! I can't tell you how thankful I am for your response!
I was starting to wonder that about the external drive itself.
Thanks!

If I format my hard drive to OX X EXTENDED (JOURNALD) format, will it erase all the contents on it?

Yes, that's what formatting will do and you will get that warning. You'll have to back the data to a folder on your main drive if there is room or to another external HD.

I use FAT32 so mac and windows can use both disk. Weird thing is, illustrator does see the disk, while photoshop does not. Seems like a hardcoded pref to use JOURNALED in photoshop while illustrator doesn't seem to care.

Open Disk Utility.app Search for it in Spotlight.
Click on Erase, and select MacOS Extended Journaled and then click Erase to remove all
data on the External Drive and to format the drive.
