Scratch Disk Full

[pixlmixgabriel]

Hi all,

 

I'm working in a school that uses adobe CC and we're having an issue with a user. When they attempt to do something in photoshop, it comes up with a message saying "scratch disk full" - we operate an Active Directory based system, the user logs in with these credentials. The funny thing is, it follows them around on whatever PC they log in to. I have checked the space on the storage drive (as google suggested) and there is plenty of space for photoshop to use (at least 40GB).

 

Any help is much appreciated as it's really bugging me 😂

Do they use a roaming profile? or redirected?

[pixlmixgabriel]

Neither, we use local profiles but redirect certain home folders

i think it depends which drive adobe wants to start from, if you've mapped their onedrive folder as their home folder I dont think adobe likes it and kicks off about the scratch disk , have seen this when students try to save to onedrive rather than a normal drive

[pixlmixgabriel]

The students home folder is a mapped drive, we don't use onedrive here. Their drives are just on the network as shared drive S: for example.

[dmason2]

is the C drive of the PCs have enough memory left? May have enough room on their S drive however does the PC's C drive have enough space?

[pixlmixgabriel]

The C drives have at least 40GB free, they aren't running out of RAM either.

Delete the local profile, we get this frequently with staff as they use roaming profiles whereas the students don't.

Are they trying to make files that are like 1,000 inches square instead of 1,000 pixels square? I've seen that happen enough times

We've seen this a bit this last term. Resetting the user profile sometimes works. Emptying the recycle bin (even when there's only a word document in there) also sometimes works. Resetting OneDrive sometimes works. Not downloading the initial file through Chrome sometimes works. Updating the OS and/or the CC install sometimes works.

 

Finally, every so often it turns out that the device actually is out of space, and 'scratch disk full' is accurately reporting the issue.

 

Very frustrating

I'll try deleting the local profiles - I tested them using 1920x1080 pixels instead of inches and it did the same thing. Currently waiting for the teacher to give me the student's name so I can delete their profile - thanks for the help, I'll let you know

I seem to remember something about getting this message if there wasn't enough contiguous free space, ie a need to defrag the drive. hashtag quaint.

In our case the scratch disk is stored in the user profile. Adobe CC needs a couple of Gb breathing space minimum, depending on the size of the image they're working on.

Hi all, turns out the students were creating ridiculously sized images which caused the disk to be "full", I should've seen it sooner Thank you all for your help

I have had to deal with it previously, even showing the teachers didn't help!

Found out the issue was down to the way Photoshop works and the machines we are using. A certain setting that was causing the issue was History states. It's default is set to 50. The problem is that each state is the exact same size as the original file. Our example file was around 2GB so in effect you would need 100GB free disk space - not including the fact that original file size goes up whilst you are working on it.

 

Our machines only have 4GB so they were using that up very quickly and then using up the scratch disk with anything it couldn't store in RAM.

You'll see from the article above that the OP had a massively spec'd machine and was having the same issue. Minimum requirements for PS is 8GB of RAM but it all depends on the file size you and using, which would determine whether you would run into this issue.

 

You can change the states yourself (We have ours set to 5) the problem is pushing this out to 40+ machines. the settings are held in the Adobe CC prefs.psp which are held in the user profiles, and since we are running delprof we either have to get the user to add the history states setting everytime they log on or somehow automate it....

 

Unfortunately Adobe CC isn't a very good product from a multi user administration point of view

You should be able to use Group Policy to push the file out at logon.

User Config - Preferences - Windows Settings - Files - Target Path C:\users\%username%\AppData...

Thanks - the only other two issues with that at the moment is that the folders for the file are only created once PS is opened - we also have multiple year groups using the PCs so you would have to create hundreds of folders at logon (clones of the same directory for each student) - I'm still trying to see if there's an easier way to do this...

We showed the kid the true size of their work which at 1:1 was the size of the side of the building.

So, create the folders as well. If you clear the profiles anyway you only need to create it for the person who is logging at at that time, not for the entire school population.
