Photoshop :: Could Not Open Scratch File Because Disc Is Not Available - Mac
Mar 5, 2013
I recently changed the Photoshop (CS6) Scratch Disk choice from the default Boot Drive to one of the other internal drives in my MacPro (OS 10.6.8).
When I restart Photoshop (CS6) I get the message:"Could not open scratch file because disc is not available" and Photoshop will not launch.
I then restart Photoshop with "Command - alt - shift" keys held down (as per suggestion at URL.....)and reset the preferences which allows Photoshop to come back.(Resetting preferences returned the Boot Drive to scratch disk status.)
I have another MacPro that - same OS 10.6.8 and Adobe CS6 - and I don't have this scratch disk allocation problem.What is going on with the one MacPro that prevents me from selecting a Photoshop scratch disk other than the boot drive?

This is my first post, and I was hoping someone can help me out. I'm looking to add a seperate internal HD to use as the Photoshop Scratch exclusively. I'am considering the WD Raptor 36GB SATA 16MB 10000RPM.
My question is: Size-wise, will 36GB be enough?
I'm on a budget. I can almost get 2 x 160GB SATA 7200 for the price of the 1 x Raptor 36GB, so I really want to be sure I'm doing the rigth thing and aiming for speed.
My Set-Up would then be:
Internal 1: 320 GB 7200 (main drive / programs & system installations)
Internal 2: 36 GB Rapter (photoshop scratchdisc exclusive)
External 1: 500 GB Mybook (all documents)

I get an error which says my scratch disc is full. The question is how does one empty an existing scratch disc? None of the manuals seem to cover this.

When I first installed Adobe Photoshop CS6 I was unable to run Photoshop or Bridge CS6. Photoshop would give me an error about "could not open a scratch file because the file is locked. If I ran either of these programs as an administrator they would run without issue, this led me to believe that there was a permission issue somewhere. After some digging I found out the both Bridge and Photoshop try to create a temp file (similiar to Photoshop Temp2777223910092) on the c: drive of the computer. In my case the user that I was logged in with did not have access to write to the root of the C: drive. Note that you run the program as the administrator and change the scratch disk location as that changes the preference for the administrator user and not the user that you are currently logged in as.
I first had to give the user that I was logged on with write permissions to the root of the C: drive. Next try and run Photoshop, you will get an error another error about the scratch disk and about and invalid or missing setting file. To correct this you need to have run Photoshop as an administrator, next you can go to Users AdminAppDataRoamingAdobeAdobe Photoshop CS6Adobe Photoshop CS6 Settings and copy Adobe Photoshop CS6 Prefs and/or Adobe Photoshop X64 CS6 Prefs to Users<your logged in username>AppDataRoamingAdobeAdobe Photoshop CS6.Adobe Photoshop CS6 Settings.

once i was reading an adobe pdf "How to get better performance in photoshop cs5" - that was in 2009 or 2010, and may be outdated, but there was a calculation method to determine the size of a scratch disc. (similar calculation see below, if i can remember right)
i am asking myself, how can i determine the correct size of an external SSD-scratch disc, only used by photoshop (completely empty):should i buy a 128GB or 256GB or 512GB SSD which is only reserved for photoshop?
basic question 1 : i guess i should avoid to set the internal SSD as photoshop scratch disc, as it slows down everything?
basic question 2 : in sense of maximum performance: better buy an external USB3.0 or thunderbolt SSD? will photoshop really use the extra thunderbolt speed when swapping data?
secondary question:
can i calculate the size regarding my daily working habits?
i am mainly working like this:
- with my imac 27" late 2013 with 32GB RAM and 256 GB internal pci-e SSD (800 MB/sec), which will stay always half empty for performance reasons.
- OSX 10.8 mountain lion and 10.9 mavericks soon
- photoshop cs5, cs6 and cc (always without extended)
- 8bit and 16bit mode
- only RGB
- with latest phocus/Hasselblad and canon RAW Files which produce a basic .psb document at ...
- 10.000 x 7000 px at 300dpi
[code]....
i wonder how to calculate ?
for example:
10.000 x 7000 px at 300dpi needs for one image layer at 16bit: 2GB RAM in photoshop cs6 or cc (just as a number), this may be wrong so lets take 2GB RAM and multiply with 10 image layers in my .psb file (16bit) = 20 GB RAM, and multiply with 20 adjustment layers (guess they need less ram, for one lets say 500MB) = 20GB + 10GB = this 16bit .psb layer file would need 30GB RAM, so when i have 32GB in my imac, i set cs6 or cc to 70% ram usage, it misses at least round 8-10GB RAM > can i guess that photoshop would swap these 8GB onto my scratch disc? or do i miss something important in my thinking?

I've been using Photoshop CS5 for awhile now (about a year and a half). Up to yesterday I was running OSX Snow Leapord with no issues. Yesterday I upgraded to OSX Lion and today, my first day using Photoshop in Lion, I'm getting repeated "scratch disc error" messages with a "quit" button (no other options). Photoshop works fine for awhile, three hours or so, and then I'll get the "scratch disc error" message and will be forced to quit Photoshop and restart.
My main drive is a 2Tb drive with 1.7Tb of available space, so I'm sure scratch disc space isn't a problem. I've got about another Tb of scratch disc space available on two other internal drives. I've got 14Gb of Ram, all memtested and working perfectly. It clearly seems to be an issue with OSX Lion since it never happened before today. A few other details: I'm up to date with Photoshop CS5, I have Open GL turned off because I'm on an older Mac Pro (a 3.0 Ghz dual quad core, 2.1) and my video card doesn't play nicely with Open GL (a whole different kind of crash).
All three times I've gotten the "scratch disc error" pop-up today it seems to have been when I open multiple files. This last time I opened something like 8 files. Big deal; sometimes I open 40 or more without any problems. I have yet to lose any of my work (I save constantly - a habit born out of past frustrations), so it's managable, but it shouldn't be happening.

I recently installed Photoshop CS5, however every time I open the application, I am receiving this error message at the loading screen:
"Could not open a scratch file because the file is locked or you do not have the necessary access privileges. Use the ‘Get Info’ command in the Finder to unlock the file or change permissions on the file or enclosing folders."
Reinstalled Photoshop many times, even the CS6 BETA is giving me the same error.Deleted preference files within /Library/Preferences/Used the cmd+alt shortcut when starting Photoshop to select a different scratch disk location.Used the cmd+alt+shift shortcut to delete the settings file, which I cannot do as the error message mentioned above appears before the window for deleting the settings file does.Tried rebooting several times, even into safemode and I still get the same message.Tried changing the permissions on the Applications folder, Adobe folder, CS5 folder and CS5 application, however they are all set to 'read & write access' for me. I am also set as an administrator.Cleaned my cache of any unnecessary files.I have also repaired my permissions using Disk Utility, but that didn't solve the problem. I have a 2010 Macbook Pro, 4GB RAM running OS X Lion 10.7.3 with 2 partitions on my hard drive (OS X and Windows 7). I have 15GB free on my OS X partition currently, which may not seem like much, however I have run Photoshop CS5 previously as a trial and other versions of Photoshop and the small amount of harddrive space has never affected the software's ability to create a scratch file.
I can use Photoshop CS5 & CS6 on a guest account that I created recently, which means that the problem I am having is permissions based. Logging into a separate account is a good enough solution for now, but it is incredibly tedious to keep changing accounts just to use Photoshop.

I am able to run CS6 when I login Admin, so i change scratch file location to D:. After restarting PC, login by Admin, I can run CS6. But I still can't run CS6 when I login by other account, I think the location of scratch file is per user setting.

my setup has 128gb ssd (C) which contains only my OS files with some junction points to Program Files/Program Files(x86)/ProgramData/Users which are located in my D drive which is a 1TB WD.
at first it showed when I tried to start PS for the first time after a clean install on a new computer I managed to get past it by runing PS as admin and changing the scratch disk to D.but now I noticed that when I try to copy a path from illustrator into photoshop as either a smart object or as pixels I get this error again. I haven't seen it again other then that but I just started using PS in this setup so I am yet to explore all the functions and whether they are working correctly or not.
when ran as an administrator the illustrator->PS transfer works fine but I don't want to run PS as admin all the time...

Running PSD 12.0.4 (Extended) on a Mac Pro, Mac OS 10.7.3. Plenty of ram; plenty of hard disk space.
I just finished installing a new 1TB drive in one of my bays; I now have (3) 1TB drives total. Initialized the new drive (Mac OS Extended/Journaled), partitioned for Lion, then installed the OS and migrated everything from my primary (boot) drive using Migration Assistant.
After finishing, PSD gives the following error on start: "Could not open a scratch file because the disk is not available". I can command+option on start, select the boot drive as scratch and set the rest to None; that configuration works (and sticks). However, if I try to set scratch volumes to either of my backup volumes, I get the same error. Additionally, Illustrator can't even see the other two volumes in the scratch disk selector (PSD sees them, but won't accept them).
Here's what I've done:
- using simple disk drive names (i.e. WD1, WD2, WD3)
- verified all drives with Disk Utility
- ran drive diagnostics on all drives using SMART Utility (no problems found)
- reset paramter ram (comand+option+p+r on Mac startup)
- repaired permissions (all volumes - no permission errors found)
- reset PSD prefs (command+option+shift on start)
- deactivated/uninstalled/reinstalled PSD

can't remember anything as having changed (ie. OS or new apps/settings). I get the "could not open scratch file because it is locked or you don't have permission" message and then PS quits.
I've tried uninstalling and reinstalling. I've tried deleting the settings file.
I'm using a MacBook Pro running os 10.7.5.

I just installed Photoshop CS4, both the 32 and 64 bit versions (part of the "Master Collection"). After opening the programs I changed the scratch disk location to two separate drives other than where Photoshop resides, where it had placed said file as a default. Now neither Photoshop versions will open.
I get the following message:
"Could not open a scratch file because the scratch file is locked..."
Just one problem, there is no scratch file visible on either of the two drives...
My operating system is Vista Ultimate on a 64 bit Quad CPU machine with 8Gb of ram, two Raptor HDs, four 750Gb HDs configured into one RAID 5 drive and Nvida GEForce 8800GTS graphics card.

No one of the used files are bigger than 20MB in file size. When opening the file, my empty hard drive space (40GB of free space) decreases to ZERO. Which temporary file on earth can be 40GB big? My system is an i Mac with 24GB RAM. How can this happen?
EDIT: I just found out this might be the so called scratch-disc. But anyway, how can a file take up this much space? Photoshop has a allocated RAM space of 16GB on my system.

When I try to open photoshop I get the following message "Could not open a scratch file because you do not have the necessary access privileges". I click OK and get "Could not open Photoshop because you do not have the necessary access privileges". It then closes.
My CS4 Illustrator opens fine. Photoshop opened just fine 2 days ago.
I tried to open Indesign and that just crashes immediately (but I have never opened Indesign before...).
The only thing I can think of that might be relevant is that my computer was stolen about 6 months ago - when I got a replacement computer I simply reinstalled the same CS4.

I want to "Delete the Adobe Photoshop Settings File", but at startup when I hold down [ctrl alt shift] I get the "scratch disc preferences" window instead. It was fine for a long while and this just started recently.
I have Windows and Photoshop CS5. The scratch disc preferences is on the first selection 'start up'.

All my MACINTOSH versions of Photoshop - S5, Elements 10, Elements 11 - display the opening start screen, but ABORT THE LAUNCH of the EDITOR with the error message:
"Could not open scratch file because of disk error."
"Could not initialize Photoshop Elements because the preferences file was invalid (it has been deleted)"
I have cleaned up my external disks so that they all have at least 100GB of free space
How can I correct this so that I can recover the Preferences, re-establish the Scratch Disk, and launch the Photoshop Editor?

using mac os I need to change my scratch disc from the default "system" to an external drive.
In preferences> scratch discs it sees the hard drive i have attached...so i choose it, I click ok and get the usual warning about having to restart illustator to implement the change. problem is, when i quit, then restart illustrator, no dice. it's defaulted back to " system". I change it again. click ok. then, just to see, i re- open the preference panel. it's already gone back to " system". what gives? i've tried over and over and it just wont take.

1) I'm unable to designate an internal drive as a scratch disc (non boot drive). Drive is clean, empty, I've chkdsk'd, permissions set to full, I can read and write files on it, and I'm able to designate it as scratch for Illustrator but PS6 doesn't like it. Says I don't have access.
2) I upgraded to PS6 extended (cloud) and after a week it now hangs during startup at loading Nik Color Efex Pro 4 plugin. Hangs for about 3 minutes before continuing.

so I got the 'scratch disks are full' message when I tried opening new projects. After googling, I read to just change the location to another hard drive instead of the main one, so I went into preferences, unchecked the C drive & checked the E drive. Now photoshop won't let me open it. I get this message:
"Could not open a scratch file because the fil eis locked, you do not have nexassary access permissions, or another program is using the file. Use the 'properties' command in the Windows Explorer to unlock the file." how do I do this, exactly?
