Unable to set scratch disc

I am suddenly unable to set my scratch disc to the internal G5 Jam 1Tb RAID set in my machine.
The message is "Unable to set scratch disc. The selected directory is on write-protected or non-writable media."
I have had quite a bit of trouble lately with the machine, and have just recently had the boot drive replaced, although I'm not sure that would affect my ability to set the scratch disc. I can write files over to the 1Tb RAID by simple dragging a folder, then authenticating the access, but I still get the above message when trying to set the scratch disc.
Any ideas?

Are you formatted to MAC OSX Extended Journalized?
Also, do you have administrative access to your compouter? Make sure your account can write to the drive.
Ctrl-click on the drive on the desktop and choose get info.
Look at the bottom and check your ownership and permissions. It will tell you what the active account can do with that drive.

When I try to use the internal hard drive as a scratch disk I get this error "unable to set scratch disk- the selected directory is on write protect or non-writable media. Any ideas on how to fix this. It only happens in fcp.

By internal, I assume you're referring to your systems (boot) drive. Is it, by chance, a partitioned dive?
Also…although many people successfully use their systems drives as scratch disks, over time you'll have better results using a dedicated drive for your media.
Good luck.

Unable to set scratch disk

I have just upgraded to Lion and have tried to use FCE for the first time with it.
I got an error message upon starting it
"Unable to set scratch disk. The selected directory is on write protected or non writeable media"
Any ideas?
Also and I dont know if it is related, when I try to export to quicktime, there is no video in the exported quicktime file only video. There is video however when I tick make self contained movie.
It is a new problem and hasn't happened before going to Lion.

Most users using Lion have trouble of one kind or another.
Short answer is Lion is not suppoorted for FCE use.
Moving to FCP X is the only supported option at this time or roll back to Snow Leopard.

Unable to set scratch disk error

I know this has probably come up before but I can't find the topic when I search. The error message says this...."Unable to set scratch disk. The selected directory is on write-protected or non-writable media."
In addition to that, whenever I try to render by pressing either option+r or apple+r I get an error message saying...."File Error: Access Denied."
Any suggestions? Thanks in advance.

Have you tried...
Trashing preferences?
Run Disk Utility?
Instead of control-clicking on the drive, try control-clicking on the Capture Scratch folder and the project Subfolder and changing permissions.

Setting Scratch discs for 3 different projects -- HELP

I have a new mac book pro and I am going to use it for some mobile editing.
I have some scratch files from my imac that apparently didnt migrate to the new ext HD that I copied everything to so I am having difficulty finding the media files "media offline" and I cant find it in the scratch folders.
I think I might have trashed it because it was in a wrong folder or mislabled one...... so here is what I need to know.
on the EXT HD that I am capturing to:
Do I need to set up a scracth "FOLDER" for every different project or just allow all projects to save under the scratch folders that set themselves up after choosing that disc?
I was setting the scratch folders to different folders on the EXT HD trying to keep them separate but I think -----I need to reset after I open up each project to do any editing correct? If not the project i am working on will save under the last project setting ... right?
thanks
any info or links to how to best workflow this would be appreciated.

When you initially set up a Scratch Folder, Final Cut creates a folder labeled "Capture Scratch", then a sub-folder inside with the name of your project. As you create new projects, a new sub-folder will be created with the new names of your project.
In my workplace, because we're Xsan based, and because of the numerous projects that are worked on, we've developed a slightly different practice. Instead of everyone's media residing within one Capture Scratch folder, we build our own folder/sub-folder structure. For example:
http://dl.getdropbox.com/u/19589/Sample%20File%20Structure.png
We use this method to keep all of our projects separated and organized, while it may seem cumbersome, it has worked really well for us.
Hope this helps.

Best way to set up a scratch disc for a shared project?

I am currently working on a project with 4 seperate computers and users working from a shared external 10TB drive. What is the best way to set up the scratch disc and media cache folders?
Each worker is editing a sequence and then posting back to the 10TB drive.

Use the identical path (including drive letter) for Media Cache,
Preview Files and source media files on all machines.
Premiere will look to absolute, not relative paths for these files.

Setting internal soft RAID as scratch disc in FCP

I have an internal 1tb RAID I use as a scratch disc for Photoshop. I want to use it for FCP. I know when I go back to PS it won't be optimal but I have a couple of shorts clips I wanted to edit and figured I could use the 1tb as a scratch. It is made up of two 1tb Samsung F1's using Disc Utility to make them a Striped RAID 0 Set.
When I go to choose a scratch drive in FCP it doesn't show the RAID as an option.
What am I doing wrong?
thanks

then i closed terminal and then when to disk utility and chose to repair disk with results all was fine. Then ran repair permissions and got similar results from terminal function next I erased disk and then chose to restore from time machine and it is now restoring! yea!

How to determine the scratch disc size?

hello,
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
- with average 10 - 40 main image layers and 20-50 adjustement layers (try to reduce that in 16bit)
- .psb file is 2-20 GB big (file in finder)
- 16bit file compression is off, when saving .psb files (faster handling)
- set photoshop to 70% ram usage (from 32GB RAM)
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?
tricky thinking
thanks for help

The rule of thumb I follow says to figure on 50 to 100 times the size of your largest file ever multiplied by the number of files you have open. I have seen the scratch file exceed 300 GB once, an admittedly rare occurrence, but it often exceeds 200 GB when stitching large panoramas and the like.
As an example—and stressing that I'm aware that others have even more scratch space than I do—I keep two dedicated, physically separate hard drives as my primary and secondary Photoshop scratch disks and a lot of GB free on my boot drive for the OS. I also have 16 GB of RAM installed.
Additionally, if you only have a single HD, i.e. your boot drive, you'd need it to be large enough to accommodate both the swap files of the OS as well as Photoshop's scratch.
- i dont use HDD anymore only SSDs, both internal and external
- i set history state to only 5 or 6, to improve performance
- i set cache size to 4 and tiles to "big and flat" with 1028kb (there is no "big and much layers" option)
- is this still the rule of thumb? i read it in 2009 , too, guess it was outdated, as cs6 and cc have improved codes in terms of performance?
- if you say "50 to 100 times the size of your largest file ever multiplied by the number of files you have open.":
i will not open more than one document at same time to prevent performance lags, so lets calc like: dokument size in finder (you mean in finder or doc. size shown in photoshop?) = e.g. 5GB x 100 = 500GB, so my external scratch disc SSD, i would buy now, should be at least 500GB, USB 3.0 or thunderbolt ... maybe better thunderbolt, yes? with usb 3.0 i could gain 300MB/sec if thats enough for photoshop?
thanks

Suggestion For An External Scratch Disc needed

I have recently learned that I had my scratch disc set up incorrectly to the same internal SSD in the Mac Book Pro. I assume that to keep the maximum transfer speed I need and external HDD or SSD with FireWire 800 instead of USB. I have found a few of those but they are much larger than what I need in GB and physical size.
I need something portable and reliable since I do most of the work on the road.
Thanks for your suggestions.

Have you considered a G-Drive mobile or G-Drive mini SSD? Both are bus-powered.
If you're ok using AC power, look at the G-Drive mini.
These are very nice units - small, reliable, good reputation.
FireWire (or eSATA if you have a MBP with an ExpressCard slot) is the way to go. USB generally cannot keep up with the sustained throughput required for video.

Photoshop 7.0 scratch disc full error.

I just reinstalled PS 7.0 on my Windows 7 Pro 64bit system and PS 7 won't open due to a scratch disc error message. When I tried to install the 7.1 update, it can't find the PS 7 folder even when I navigate to it. I tried ctrl-shift-alt keys together but I still can't get it to open so I can set the scratch disc preferences. What are the shortcut keys to use? Any suggestions why I can't update PS 7? Thanks.

Your hard drive is larger than 500GB and the program can't deal with this and/or there are permission issues. Downsize the partition, make sure you have the permissions set properly. Regarding teh update you are probably out of luck. Those old versions cannot access the changed registry structure and thus do not find the necessary information...

Can I change the location of the scratch disc without causing problem?

Hi,
I just noticed that I set my scratch disc in (on?) the internal drive, but I prefer to have it on an external. I'm in the middle of editing a project now, will it cause confusion to FCE HD if I change the location of the scratch disc?
Thank you for your help.

No.
You will have stuff in two locations and just as long as all changes are done within FCE it will know where to find things.

Photoshop CC scratch disc error

I'm having a frequent scratch disc error program when coming back to my computer after being away. I'll pull up the program ... which has already been open and it'll just say "a scratch disc error has occured" and then shuts down.
my local hard drive where photoshop is installed has 250g free
I've got an external drive set as an additional scratch disc with 1.51T free.
It seems like it could be more of a sleep issue or something with coming back to something that was already open and maybe the external being asleep? But that seems highly unlikely for it to just go "meh. whatever. close." when locally there's still plenty of space left.

I have not had any real problems with letting my workstation with an external disk enter sleep state. When the system wakes up I have often notice the my external 4TB Seagate usb 3 drive take some time to get running and will often see Windows Autoplay popup window for the drive. However I don't use that drive for application work space like Photoshop scratch space. For application may be off and running before the drive is ready after sleeping. I find the USB3 external hard disk performs almost as well as my internal 10k RPM 500GB disk. I did not expect that.

Why do i get the message about scratch discs are write protected

I recently bought Premiere Elements 13. It worked fine until yesterday. I suddenly began getting the message about "scratch discs are write protected..." and I have not been successful in learning how to correct this. I have checked online only to have so many varying "solutions" that it is confusion. I tried a couple with no luck. As it stands, I can't be sure where to find the files since they aren't going where I had them. It is very frustrating! This appears to be a common problem but what is the method to eliminate it? Thanks.

ccchaney
On what computer operating system is your Premiere Elements 13 running? Have you updated 13 to 13.1 yet from an opened project's Help Menu/Updates?
How do you have the project's Scratch Disks set up currently - for each, location and amount of free hard drive space at the location?
Please see Edit Menu/Preferences/Scratch Disks. https://helpx.adobe.com/premiere-elements/using/scratch-disks.html
Please explain/clarify what you mean by
As it stands, I can't be sure where to find the files since they aren't going where I had them.
What files? And, where are you putting them?
What are you doing in the project when you get the message about the Scratch Disks?

Do I have to specify scratch disc location each time?

hi all ive just finally found my self in a position to have a dedicated hard drive for cache, scratch disks etc.. WHen I create a new project I go to the scratch discs tab and specify the hard drive as the location for them, however I find myself having to do this every time i create a new project.. can I not set it to default to there, if so could somebody explain how?
many thanks

The answer is "no" and "yes".
If you put your cache where you put your projects then each time you create a project, your cache will follow. That is probably not a good idea for most people, but it is not bad if you store your projects on a separate drive specifically set up for the purpose of putting projects and cache.
If it is not a good idea for you, then you may find that you want to do what I do. I have a few project templates I use. They are not officially templates, but I think of them that way. They have all of the settings I like to use, they have the right number and the right type of tracks, they store the cache on a specific drive set up for that usage, they have some generic footage with certain effects applied so I can copy those efects when I need them, and they have my logo, and intro music.
When I want to create a new project, I merely copy the directory that the project is in and open the project in the new directory. That probably saves me 10 minutes of gathering resources and another few minutes of set up. Every time.
