Scratch Disk Issue

video capture video render and audio render are checked off but not audio capture and I am unable to check it off. I'm assuming this is supposed to be checked off if so may this be the cause of other audio problems i'm having

The audio capture select is available only if you have the record audio to separate file option selected. This is a legacy option left over from the days when you'd put video and audio on separate drives to increase data rates to/from the hard drives. It is no longer necessary.

Weird RAM/Scratch Disk issue

Having a weird memory problem with Photoshop CS4 on my G5 Quad.
Let me see if I can explain this properly....
When I open up a file in Photoshop, I notice that the available space on my hard drive reduces (info at the bottom of any Finder window). Essentially, it's using the scratch disk.
I would expect this with a very large file that exeeds the amount of ram in the machine. But it does it even with files of 5-10 Mb. It appears to me (just a guess) that Photoshop isn't using RAM when opening or manipulating a file. Though I have more than enough to open it.
Even when I close the file, or "purge all" from PS's edit menu, my available disk space does not come back. Only when I quit out of Photoshop completely, will it come back.
Make sense?
No other application seems to be having this issue. Any ideas on what might be causing this?
I've run Apples Disk Utility, and everything came out fine. Ran TechTool Deluxe, and no problems there either. Hoping maybe I'm just missing some piece of the puzzle first, before I uninstall/reinstall Photoshop.
System specs:
G5 Quad (2.5 GHz)
4 GB RAM
OSX 10.5.8
Photoshop CS4 (11.0.1)
Memory usage set to allow up to 70% (but doesn't seem to matter what I set it to)

This is normal.
Photoshop needs to allocate scratch space for data, in case it needs to write that data to disk later -- otherwise you would randomly fail with "out of scratch space" in the MIDDLE of an operation.
Photoshop is using RAM, but needs to allocate the scratch space, and make sure the allocation succeeded.
And yes, RAM and scratch space get reused, so rarely decrease.
Other applications that deal with datasets larger than RAM will have the same issues.
And technically your OS swapfiles do the same things.

Scratch Disk Issues

Hi there,
I'm new to Photoshop and am currently having some issues. On my PS CS6, I am unable to use the text tool because my "scratch disk" is too full. What is the recommended way to go about clearing/freeing space on my scratch disk without losing important files?
Thanks for the help,
Bri

What are your Performance Preferences? Specifically what is your primary Scratch Disk?

PS5 won't start Scratch Disk Issues

I would really appreciate some help - I'm working to a deadline and got it into my head that I could speed things up if I reallocated my scratch disk to a bigger HDD (I have a Mac Pro with 4). So in a brain-fade moment I assigned the 3 non system disks in priority order BUT deactivated the Scratch Disk on the System drive. Photoshop will not now restart and gave the following error messages: "Could not open a scratch file because the disk is not available". followed by "Could not initialize Photoshop because the disk is not available". I went back 24 hours in Time Machine expecting that to fix things but, alas, no change. How can I reassign the scratch disks with the program off?

Yes, because I managed to fix the problem with Mac Command+Option+Shift .... DOH!
Thank you all very much.

Scratch disk issues when trying to start CS4

while working on a large file in CS4 my scatch disk filled up.In preferences I foolishly changed the scratch disk to my D (backup) partition and shut down PS. Now when I try to restart CS4 i get the following message. "could not open scratch file because the file is locked. Use properties command in the windows explorer to unlock." I'm having no luck with this. Any ideas?

Reset the PS prefs by holding down Ctrl+Alt+Shift when the program starts.

Cannot change scratch disk in premiere 2014

I'm asking this again as my first attempt went into empty space.
Whenever I change the video / audio preview scratch disks, close and then re-open premiere, they return to the original, i.e., "same as project."

Hello,
We're aware of the Scratch Disk issue and are investigating the cause.
Sorry for the inconvenience. The workaround for now is, set the customized location when first creating the project, then custom path should remembered.
Hope this helps,

How can i make my external hard drive be the scratch disk with 1 FW input?!

Hello! I use firewire with my external HD AND my camera...however i only have one firewire input...i set my scratch disk for final cut to work with my external HD but when i am importing footage to my computer with my camcorder, i can not have my external HD plugged in, thus the scratch disk has to be set to something else to continue working. So how can i work around this problem?! Should i just change the settings back after i import the footage and it all goes to place?

I don't understand the need to daisy chain. I have one Firewire port on my MacBook Pro, and I use a Firewire hub. I've been connecting two 1TB Western Digital My Book Studio Edition hard drives (one for FCE and iMovie projects; one for the media files I create via export), and a Canon NTSC ZR200 miniDV tape camcorder, or a Sony Digital8 tape camcorder, or sometimes a Canopus ADVC 110, without issues. Why not use a Firewire hub? . . . except to save the small expense.

Save as Photoshop PDF Scratch disk locked?

I searched the forums, but apparently my issue only crops up when someone tries to launch PS. I can launch and do everything else just fine; however, I attempted to save as > PDF and received the scratch disk locked message. I can successfully save as PDF if I use the launch as admin option, but this seems odd since I can do everything else just fine without the need to do that.
Here are my steps:
Save as > Photoshop PDF
Click OK on "The settings you choose in the Save Adobe PDF dialog can override your current settings...."
I change [b]nothing[/b] in the Save Adobe PDF dialog. I simply click Save PDF.
Select Yes for "Preserve Photoshop Editing Capabilities" in the prompt.
Here is where I get the error message.
"Could not open a scratch file because the file is locked, you do not have necessary access permissions, or another program is using the file. Use the 'Properties' command in the Windows Explorer to unlock the file."
At this point, Photoshop does not crash or exit. It just simply will not save the file. This is the first time I've tried to save as PDF, so it could just be a user error > replace user situation. :d
I have tried the CTRL + Shift + Alt method of launching to wipe my preferences only to have the same result. My scratch disk is an internal drive used only as storage with 1.30 TB available.
Photoshop CS6 Extended
Windows 7 64bit
User account is an admin, but I have never had a need to launch PS as an admin specifically.
Thanks in advance.

Checked my permissions on C:\Users\***\AppData\Roaming\Adobe\Adobe PDF\Settings and everything is fine.
Taking that info and some google work I came across this: http://help.adobe.com/en_US/photoshop/cs/using/WS23B45D06-1977-4006-8BEB-2DBB08CA502Ea.htm l#WSA79FA899-BC95-401e-BD44-5B26BC31B369
Apparently, there should be PDF settings files in C:\Users\***\AppData\Roaming\Adobe\Adobe PDF\Settings; however, my folder was empty, but the article above also says to move them from an 'Extras' folder located within ProgramData. Copied the settings over, tried again, same result.
Am I supposed to have Acrobat installed for this to work properly? I don't have Acrobat, nor do I even use Reader (I use a different program for in-browser PDF).
//edit
Apparently it was in my settings on the PDF save dialog. I removed the settings that I moved over and tried again. This time I actually fiddled with the settings and used Smallest File Size instead of HQ Print, and that seemed to have worked. Messed with things some more, and narrowed it down to the Preserve Photoshop Editing Capabilities option. As long as that option is UN-checked, then everything works smoothly, including HQ quality.

Error when launching Photoshop - cannot modify scratch disk preferences

Hi all,
I recently installed photoshop CS5. When launching it I get the following error:
'Could not open a scratch file because the disk is not available'.
I went on this forum and found out several threads relevant to that issue. I did the following to try to fix the problem:
Did a clean uninstall of CS5, made sure no file pertaining to CS5 were remaining
Reinstalled CS5
As the problem was still occuring I did the following (as hinted in the threads)
I reset the photoshop preferences according to http://forums.adobe.com/thread/370735?tstart=0
I modified the setting of the drive HD (read & write everywhere, share folder checked)
I then tried to change the scratch disk preferences (launch photoshop then click Option+Command+Shift)I can select my disk but the selection does next time I try it is still the same (c.f. screen shot): first = startup, second = none, etc.)
I would really appreciate if someone could help me on this one.
Thank in advance,
Francis

I have one drive, but the point is rather that when I select it (=macintosh HD), it is still Startup that appears in the menu as depicted above on the next launch.

Setting up RAID 0 and scratch disk from blank drives?

Folks,
Howdy again from NC. I've been setting up an AMD Phenom II 955 to handle PPro CS5 as well as possible, within limits. I built four of these machines for my math class, and am going to give CS5 a go on one of them before caving in and migrating my Production Premium to an i7/X58 platform. Maybe I'll get lucky and find this computer works acceptably with PPro, especially if I transcode my T2i AVCHD footage (likely Neoscene).
I put three new disks into my build yesterday and would like some pointers on setting them up, if I may ask. I have read through a number of posts on this, but don't find direct answers, unfortunately. I've never set up a RAID and want to get it right.
I have two Caviar Black drives for my RAID and a Hitachi Deskstar for my scratch disk. The Blacks are new out of the pack and the Hitachi has had zeros written to the drive. How to begin?
Anticipated issues:
* Do I need to format the drives in a certain way? I had planned on going into Disk Management and setting up a volume on each as my first move. Right now, they aren't even recognized under My Computer. Under Disk Management, all three show as unallocated.
From memory, I right click in the unallocated space and select an option for setting up the volume. Prior to this I only used straight-up drives, no RAID, and after writing zeros to a drive selected "New Simple Volume". It seems to me this is the move to make on the single scratch disk.
But how about the two RAIDed drives? We also have options to set up as "New Striped Volume" or "New Spanned Volume". If the answer is to set as as "New Striped Volume" for the RAID 0 I have planned, do I do this before or after installing the RAID software?
* My documentation for setting up the RAID on my motherboard doesn't indicate when to change my BIOS setting for the two SATA channels from IDE to RAID. Should I do this before or after running the software to set up the RAID? Do I need to go into the software setup with the two SATA channels already configured as RAID?
Right now, all SATA channels are configured as IDE.
* After getting my disks set up, I'd like to optimize my system for editing (turning off unwanted features, etc.). I've been looking all over for a link to an outside site I had bookmarked from a prior post, but lost it on re-install. Anyone recall what the favored link was? It started as a long page of instructions in simple typeface.
In the end, my disks are as follows (unless someone makes a case to use them differently):
OS/Programs - 1TB Caviar Green. Yes, I know the deal on green drives, but I needed to use this drive somewhere. I figured using it as the OS drive would be the best spot for the slowest drive. Maybe I botched this and should have used the following drive for the OS? I had transfer rates in mind and thought the Scratch drive should be faster?
Scratch - 750GB Deskstar 7K100 series. This drive was tops 18 months back when I bought it.
RAID 0 - Two 640GB Caviar Blacks (32 meg cache, twin processors). A bit older in the Black lineup, but the drive charts show them working quickly.
To ask one dumb last question, which will really show my newbieness, I use the scratch drive for page files (right? and what else?) and the RAID for holding any media to be worked upon and for encoding the final project?
I've been reading on this forum for over a month and am amazed that as I have the drives for a RAID, I can't find good links to tell me what to do. I know I am asking redundant questions here but have already spent two hours with the search engine and am only getting tangential anwers (ha! math joke).
Sorry to be asking such newbie questions all over again, but my luck with the search engine hasn't been so good of late. Maybe Bill's idea of creating a sticky section for common questions is a good idea.

about 75-80% of the systems we ship, ship with this config (others would be bigger arrays or no array)
1)OS
2) project drive 2 x raid 0
3) render to/export drive 2 x raid 0
4) back up (pick your poison)
while i cant speak to the older WDs (we have not used them for 3-4 yrs until now)
i can tell you with Seagate and now WD we have not seen the issue that applies to this inRaid 0
we are aware of the timeout issue this happens with controller cards and seagate or WD with large raid 5/6
simple answer use enterprise drives for raid 5/6
if you look at all the external raid resellers Sonnet etc they all use enterprise drives (mostly seagate)
so do we for large raids.
(drobo does not so buyer beware (green), we like to sell drobo without drives in it and use ours)
again BACK UP do not assume your raid 3/5/6/10/1 whatever is bullet proof, trust me its not
so even if you have a loss it should be at best nominal
something i dont think i have seen mentioned enough either
the single most common cause of drive failure (or any component failure) is Dirty Power!
dirty power can be spikes but are usually brown outs (very common in large older cities) or even low voltage coming into the home/office
this is the most common.
rather than a clean 120v you could see it as low as 105v
the other is being on a circuit with a large appliance.
ever see your lilghts flicker when the AC kicks on?
buy a good inline filter UPS. add 20% MORE wattage than your power supply
dont forget to add accessories LCDs, Audio interfaces, speakers/studio monitors etc.

Switching scratch disks mid-project

I'm moving a project from my old Vaio laptop to my new iMac. I've transferred the media and project file fairly easily. Are there any pitfalls to be aware of if I now change scratch disks settings to an external drive? Previously everything was on one and the same disk. Now I've got 2 external SSDs and the iMac's internal SSD.

MM was very buggy in v4 and v5. So much so it was generally referred to as "Media Mangler" .
It was greatly improved in v6 and v7. I haven't had issues with the later versions.
The main problem with it now is the documentation is not exceptionally clear and a poor choice for how to handle the media can lead to a disaster.
Cheers,

What about Scratch Disk fragmentation?

I edit TIFF image files with lots of layers that range in size from 50MB to 90MB. With only 4GB of RAM, my system relies heavily on scratch disk performance for these large files. I have a non-system internal SATA HDD with an 80GB volume dedicated as a scratch disk.
I have read that it's important the scratch disk be a defragmented volume. I have also heard that Macs defragment files smaller than 20MB automatically, which I don't think helps me much.
My questions are, does Photoshop CS4 delete/remove files on the scratch disk after an edit session ends and PS is closed, and then starts with a "clean slate" when re-opened? Or do all the scratch disk files just pile up in pieces over time that tend to fragment the scratch disk? If so, does the scratch disk need to be re-formatted (erased) regularly? Thanks.

Marian Driscoll wrote:
If there is nothing on that 80GB volume (when Photoshop is closed) then there is nothing to worry about. Fragmentation is only an issue if the drive has files on it.
Thanks Chris and Marian.
I have been monitoring my scratch disk in Disk Utility and have noticed that after closing PS, the amount of disk space indicated as being used drops from about 1GB to around 60MB, with the number of files indicated on the disk dropping to around 40. When I erase the volume using D.U., then there are 32 files indicated as being on the volume.
So apparently, there are files being created by both the OS (around 32 files) and also PS (around 8) that remain on the scratch disk after PS is closed. Maybe these PS files are just "place-holder" files, because the amount of space used by these PS files appears to be less than 1MB. Relative to an 80GB volume, this seems rather insignificant.
Nevertheless, I'm now thinking that it may be a good maintenance practice to erase (re-format) my scratch disk once a month or so just to help optimize it. It's easy to do in Disk Utility.

Scratch Disk is Full

When I try to crop a picture, I am getting an error message that says my scratch disk is full. I have ample space left on my hard drive, so how can I correct this issue?
Thanks,

Hello!
I don't know what version of Photoshop you are using (I'll post an example with Ps CS5, but it is similar in other versions), but I know a possible cure: check the units of the crop you are trying to perform on the image:
Are you sure that you want to crop it (for instance) 800x600 INCHES, multiplied by 300 PPI? (creating a 144 megapixels image!)
Set the unit to pixels, and you won't get that warning anymore, or change the PPI value to a smaller value.
What happens exactly? Unlike a real world crop tool, Photoshop's can be used to increase the dimensions of a document, and cropping a 1280x720 pixels document in the way the crop tool is set in the first example would create a 24.000 x 18.000 pixels one!
When you use the crop tool, it is also possible to make the document bigger by dragging the crop tool boundaries to the outside of the document. (make sure in this case that you increase the number of pixels to account for it.)

How do I setup the scratch disk on a 2nd internal drive?

I am having difficulty setuping up a scratch disk on a 2nd internal hard drive for final cut pro X. When I go to file/import the second drive is not visible. Any ideas....
Thanks!

I had the same issue with my iMac and 2 internal disks: system & applications on 256GB SSD, another 2TB internal hard disk that was meant to store media, and Final Cut Pro X 10.0.3 just wouldn't see my 2TB internal disk. Only the SSD would appear in the Event Browser.
I solved it by checking read/write permissions on the hard disk. I have 2 users: one with admin rights which I used to initially set up the iMac and install software (including FCP X), and another user with standard rights for everyday use (including FCP X production).
My 2nd user only had read permissions on the 2nd internal hard disk. I selected the disk, Command-I, changed permissions to read/write, and when I launched FCP X again, both volumes would show up now. Issue solved!
Hope this helps.

Photoshop Scratch Disk Error OSX Lion 10.7.3

I have had Photoshop CS5 installed on my system for over a year, and it worked fine all this time under Snow Leopard. Now that I've upgraded to Lion, Photoshop will not open due to these messages:
Could not open a scratch file because the disk is unavailable.
Could not initialize Photoshop because the disk is unavailable.
The scratch disk in question is an 80gb partition of a 1tb internal hard drive. If I delete the preferences file (by holding down cmd-shift-opt when starting PS) then it starts up just fine. If I go into preferences and reset it to use the scratch disk, then next time I try to reopen the program I get the same 2 error messages and I have to ditch the preferences again.
There is nothing wrong with the disks, I verified them. And anyway, I've been using that scratch disk with Photoshop for the last year with no issues. It was only after I switched to Lion that this started happening.
I need to be able to take advantage of the performance increase that a scratch disk offers. Anybody have any ideas on what's happening or how to solve this?

Chris,
Thank you for responding. I think you're onto something. I looked in disk utility to see if I could repair permissions on the scratch volume, as Lundberg suggested, however the option to do so was greyed out due to this message: "Not available because the selected disk is set to ignore ownership". So I went to the partition, pulled up the Get Info box and saw that the "Ignore Ownership on this Volume" box was not checked. I checked it to see what would happen, and although the option to repair permissions is still greyed out in disk utility, now Photoshop starts up perfectly, even with the problematic scratch partition set as the primary Photoshop Scratch Disk.
Is this the wrong way to get to the right answer?
Concerning your other suggestions, I was able to use Go To Folder to get to the /private folder, and I saw that it said I could only read. I was able to add my user account and give it Read/Write permission through the Get Info dialogue box (I fear Terminal unless I have explicit instructions). Is this what I want? I also looked into the /volumes folder and apparently there is nothing within it, unless the folders are hidden I suppose. I checked permissions of my main drive (startup disk, on which all my applications reside) and they claim that I have read/write privileges. However I'm only viewing this in the Get Info box; is that not the right place to see/alter it? Because this whole time the scratch partition also claimed that I have read/write permissions and that was obviously not true, as it only started working right once I checked "Ignore Ownership on this Volume". But it's incredibly confusing because I could save files to the scratch drive from Photoshop; I just couldn't choose it as a scratch drive.
The short question is: is it ok that I simply chose to ignore ownership on these disks, and that I messed with the /private folder, and/or do I need to do anything else?
