Using a RAID as a CS3 beta scratch disk

I recently set up a RAID in my Mac Pro, creating it with the OSX Disk Utility. It functions fine as a faster, larger storage space. But when I try to select it in CS3 beta as my Photoshop scratch disk, it does not appear in the list of drives available.
CS2 does use it as a scratch disk, but the beta appears stuck in using the system disk.

I don't know of any reason wh the CS3 besta won't select your RAID set as a scratch drive so, I would suggest you contact Adobe through their bug reporting system and see what happens.
FWIW, given my boot drive is a RAID set CS3 beta does seem to work with it without issue.

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.

Using an Xserve AFP Share as a 'Scratch Disk'

Many thanks in advance for any advice anyone can give me.
I run a 100 client network at a media college where i work, and all of our students login to clients with Open Directory and their User Shared folder is shared via AFP.
Our students currently each have a portable firewire hard drive to store 'Final Cut Express' projects on. Long story short, they have to go, and we need a networked solution, effectively setting the Final Cut scratch disk settings to an AFP sharepoint.
Now on paper this SHOULD be possible. In Final Cut Express they only work with DV-PAL, which is around 30-35mbit/sec, we have a 1gbit/sec CAT6 network, and only a maximum of 12 students will be working on video at any one time. Our main storage XServe Intel server (2008 model) has 2 link aggregated 1gbit/sec ports effectively giving us 2gbit/sec. Our switches are not cheap unmanaged switches but proper rack mounted managed switches costing £4000/$6000 each.
Now as i said on paper this should be possible, but would it work in practice? I've tried a few tests with some test setups, and everything seems nice and fast so far, but of course reality is very different.
A lot of people will say that we need fibre networking and massive RAID arrays, but we simply cannot afford it. We're stuck with what we've got.
The best we could probably afford is an 'Xserve RAID Card' and then setup RAID 0 across our 3 SATA Apple Drive modules in our XServe, would that improve performance that much for FCE compared to the software RAID we currently have setup?
Is the whole idea ridiculous?
Thanks again for any help you can give me.

Going back to CS, I tested this on a Toshiba laptop. It worked, with about a 20% slowdown, IIRC. Could not find my benchmarks (probably still on that old Toshiba).
I agree with Chris - way too slow, and with rapid reads/writes, USB 2.0 devices are prone to errors, especially the dreaded Delayed Write Error. That can be death with image, or video editing.
Using eSATA is a much, much better solution, and I find that FW-800 works OK (though I have never needed to put the PS Scratch Disks on it), even doing intensive video editing.
Good luck,

Can I use my old g5 tower as a scratch disk for my Macbook Pro for Photoshop?

I just made the laptop jump away from towers and am a little shocked by how much difference a smaller scratch disk makes. Can I use my old tower as a scratch disk to help out my new Macbook Pro?
Any other tweaks I can do to speed up large files in Photoshop? Should I bump up the ram usage by Photoshop above the recommened percentage?

Hm. It sounds like you know what you are talking about, and apparently I don't. I was just going to plug in a firewire cable to both and hoped that magically scratch disk would appear as an option for my tower.
Cant I somehow boot the tower as using as a hardrive only? Or applesharing or something else?

*Noob* Which of these would I use for a scratch disk? How much Ram?

Hello, I am fairly new to Photoshop as I have used Lightroom ever since I've been a photographer. I recently got into Photoshop with the cloud as well as layering multiple exposures together. I never KNEW anything about scratch disk, until yesterday.
First let me stress, please answer my questions in layman's terms. I search the net before I start a topic on a forum and I read a lot of answers that seem to be responding to people who have a general idea of what is already going on. Remember, I DO NOT. Here are my questions:
A:If the scratch disk acts like RAM, do I need to allow it to use any of my ram at all? If so, how much? I have two Macbook Pro's, they are the highest model Apple makes, both have SSD drives, Quad Core i7's, etc. I unchecked my Macbook hard drive and told it to use an external SSD drive that is plugged in via USB 3.0. Would it be better to use an HDD instead of SDD? I have lots of hard drives to choose from due to being a music producer.
B:When I exit the program does it delete all the data it created? This question is two fold, does it delete it regardless if I saved the project or not? If I save the project does it stay there? What if I delete the original photo, was the photo imported into photoshop upon camera raw?
C: Like question A, how much ram do I choose? I have 16GB of Ram in each of my MacBooks.

OK, I have now copied your hillbilly text and pasted it into a text editor to change the typeface so I can read it.
I'll try to address the lose ends here.
A:…I have two Macbook Pro's, they are the highest model Apple makes…
Please forgive me for not being impressed. I just happen to consider any laptop a sub-optimal choice for Photoshop photography work. My personal opinion. (Please don't ask me why.)
, both have SSD drives,… I unchecked my Macbook hard drive and told it to use an external SSD drive that is plugged in via USB 3.0. Would it be better to use an HDD instead of SDD?…
I assume you are talking about using the external drive as your primary scratch disk, not as your boot disk. That is the appropriate thing to do. HD or SSD will both do the job fine, as long as they're physically separate, dedicated Photoshop scratch disks.
Obviously the internal drive will be your boot disk. Adobe applications really like to reside on the boot disk, the drive where the OS resides.
B:When I exit the program does it delete all the data it created?
This question is two fold, does it delete it regardless if I saved the project or not?
If I save the project does it stay there? What if I delete the original photo, was the photo imported into photoshop upon camera raw?
NOTHING is ever imported into Photoshop, ever. You use Photoshop to open your files exactly where you put them in the Apple Finder. And you save them wherever you wish, in the Finder as well. Your images will always reside in the Finder.
You don't import files into Adobe Camera Raw either. You open them in or with ACR.
Of course you need to save your data, not only when you quit the application, but at frequent intervals while you're working on it. Nothing you saved will be deleted by Photoshop. How can you even conceive and ask such a question? ?? !
If you ever try to close a file or the application when you have open, unsaved files, the application will ask you for confirmation in an unmistakable way.
Your images will always reside in the Finder, wherever you put them.
Photoshop does not have the abominable "Libraries" scheme that made me detest Lightroom when I tried it. Nor does Photoshop hide your image files in "packages" like the even more abominable iPhoto does.
Please forget anything you may be accustomed to in Lightroom and/or iPhoto, and approach Photoshop with a fresh mind, respecting it like the granddaddy of image editors it is.
C: Like question A, how much ram do I choose? I have 16GB of Ram in each of my MacBooks.
Again, you don't "choose RAM", instead you select a percentage of dynamically changing Available Memory (not RAM; see above) to allow Photoshop to use. Leave at around 70%.
Please see the following post for an important tip.

Anyone know how to reset the lens correction filter? (it's using the wrong scratch disk)

OK, to back up a little, I recently discovered that photoshop was using the wrong drive for it's scratch disk (it wasn't obeying the preferences I'd set). So, I reset the photoshop preferences file (ctrl-alt-shift & open photoshop).
Trouble is, the lens correction filter is still using drive "F:" (my only scratch disks are C, D and I). It access it at a root level and creates some temporary files while the filter is in use.
Does anyone know how I can get photoshop to behave?
Thanks

Photoshop not using scratch disk for PDF generation

Using Adobe Photoshop CC latest release - Set Scratch disk to S: drive. Photoshop consumes all of my c: drive using C:\users\<username>\AppData\Local\Temp for the temporary folder when generating a PDF.
How do I make Photoshop CC point to the S: drive for temp

I created a Junction with MKLINK from C:\users\<username>\AppData\Local\Temp to my solid state drive S:\MKLINK_TEMP so I was able to work around this.
It is taking over 30 minutes to generate a PDF from Photoshop
I upgraded to CC 2014 versions on all my applications yesterday as well.

Is it Necessary to create a New Folder on my Scratch disk for new project?

I am using a MACBOOK Pro with a 1tb scratch disk (loud) and am new to FCPS2. Someone told me to make a new folder on the scratch disk and then let the app build the rest of the folders it needs within it..Is there are reason for his? Do I have to build a new folder for every new project? Does media Manger do this?

Is it better to have
A) a file for each project, with all the Audio Render, Autosave Vault, Capture Scratch, Render Files,
Thumbnail Cache and Waveform Cache folders inside each one? For instance, "Ghost Story/Audio
Render, etc etc" "Music Video/Audio Render, etc etc"
Caches sholud go on your system drive. Autosave should go anyplace except your system drive so you can recover a project if the system goes down. Media folders go on your media drives.
B) All of the Audio Render, Capture Scratch, etc folders, with the project-specific folders spread out between all of these?
They aren't spread out, they're contained within.
but just wondering if there was a quick answer for this--
it seems like FCP wants users to do it according to option B,
but to me option A makes more sense
That's the trouble the OP was having. Attempting to impose your desires onto FCP is dangerous without thorough grounding in the FCP Way. I think Apple's organization structure is lame, unnecessarily restrictive, and confusing. But all of my attempts to impose my own thinking patterns upon FCP lead directly to disaster.

SCRATCH DISK MYSTERY

Hi Gang
I've got several external drives - I always use at least one of them for Scratch Disk, (since my 2nd internal is filled). I was capturing to an external drive designated 'OWC 6'. I checked system settings several times to make sure. However at the time I didn't realize that there was no sub-folder called 'FC Pro Documents'.
Please see the Screen Shot;
http://www.locationstudio.net/NoSubFolder.jpg
I started to get the Beach Ball and couldn't understand why? Had to do several 'Force Quits'
Finally I trashed preferences, and that's when I saw the Sub Folder. Please see the Screen Shot;
http://www.locationstudio.net/SubFolder.jpg
Things seem 'ok' now, but I see that the captured video wound up on the system drive.
Anyone have any insight into this puzzle?
Thanx
Mike

Hello Rienk
... I'm capturing Mini DV Tapes at 720x480, 29.97 and I checked the Film Log for confirmation of this.
Well, shouldn't give a problem whatsoever
I've been working on this project for 5 years - never any Beach Ball problems until I installed a new reliably proven WD 640GB system drive - any problems with drive? - I seriously doubt it.
Proven Reliable? Who says? Some disk reviews? Or that you had 10 of those before? Doesn't say anything about THIS disk. But I get your point.
I first got the Beach Ball, after I inadvertently/accidentally captured some video into my system drive.
It is unclear to me if you changed the media that you captured to the internal system HD to the extaernal HD AND reconnected the masterclips in the project to that media on the external disk...Did you do so?
Ever since then, I haven't been able to get of it, even after I double check the Scratch assignment. When does it occur? It's indescrimate - can't pin it down.
Did you import a lot of stills in the project? Do you see this behaviour on other projects? Does this behaviour stop when the OWC 6 is detached?
Tell us what you did to descriminate the problem.
I also originally asked about and posted these screen shoots;
http://www.locationstudio.net/NoSubFolder.jpg
I saw those. Sorry not answered that one. Well actually it shouldn't really matter. As lomg as FCP is finding the clips, it can play them. The folderstructure has nothing to do with the performance of FCP. As long as you don't try to play back footage from the internal system HD.
Finally I trashed preferences, and that's when I saw the Sub Folder. Please see the Screen Shot; http://www.locationstudio.net/SubFolder.jpg
Same.
Does the Sub-Folder make any difference?
No. Not for the performance. It does bring your newly captured footage in another folder. that's all.
When I get time, I'll try David Kuhnen's suggestion.
How are the disks attached? FireWire 800?
Other footage than DV? Stills, JPEGS, etc?
Tried reinstalling FCP? Asking this, because you had a new internal system HD.
Installed everything fresh? Or updated from the old HD. Could cause all kind of performance issues.

What's the optimum Scratch disk setup for a Macbook Pro?

Hello Everyone,
I'm starting to edit video on my Macbook Pro. I'm going to need a scratch disk. Should I get a dedicated 3.5" scratch disk or should I spend the same money on a new HD for my Macbook pro and just use the stock 200gb drive as the scratch disk? It's a mutiuse system... If you were in my shoes, would you put the newer, faster HD inside my computer or use it as a scratch disk?

Just to jump in on this, and add to the orignal post. I have a Macbook (not pro) and I need to get a external HD. I'll obviously go for Firewire, the only problem I can forsee is importing footage from my DV camera, which is also Firewire. My Macbook only has a single Firewire port. I know most externals have a Firewire Hub built in, enabling you to connect through there, but is that sufficient, will the transfer rates be ok for DV capture, as it seems like the footage would have to go from the camera, to the external Hard Disk, to the Macbook, and back to the Hard Disk, seems like a big effort, which could lead to dropped frames.
I'm sure this has been encountered before, just asking another question to add to the original post, and also to help me decide.
One other thing, if it is ok with DV, would it be ok with Hi Def, as I plan to upgrade the camera some time soon, so I wouldn't like to pick something, that would soon be useless.

Scratch Disk not where it should be

Hi all,
I can't get my Scratch Disk to appear in the place I've selected in System Settings (i.e to my second internal hard drive called Video). Here's what I've done - can someone tell me where I've gone wrong?
1. Chosen the new hard drive using the Set button in System Settings > Scratch Disk for Video Capture, Video Render and Audio Render
2. Chosen the same hard drive using the Set button for Waveform Cache, Thumbnail Cache and Autosave Vault
In the Video hard drive, I now see folders for Autosave Vault, Thumbnail Cache Files and Waveforem Cache Files, but not the others. There is no folder called Final Cut Express Documents.
Thanks heaps,
Andrew

That's how mine is as mentioned. The system drive has the Final Cut Express Documants folder whereas the external does not. It should have one called capture scratch and that's where audio and video render files go as well. Everything else I keep on the system drive.

I've lost iWeb and thus my web design. I must start from scratch. Should I reinstall iWeb 09 and use that, or is there a better way?

I've lost iWeb and thus my web design. I must start from scratch. Should I reinstall iWeb 09 and use that, or is there a better way?

The file you really need is named Domain.sites2 which resides in your Home/Library/Application Support/iWeb foldler. It's independent from the iWeb application. If it's not in there do you have a backup of your hard drive from an earlier time?
Resinatll iWeb 3 from the iLife 09 disk or wherever you got it from originally and then try what's described below:
In Lion and Mountain Lion the Home/Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and press the Return key - 10.7: Un-hide the User Library folder.
To open your domain file in Lion or Mountain Lion or to switch between multiple domain files Cyclosaurus has provided us with the following script that you can make into an Applescript application with Script Editor. Open Script Editor, copy and paste the script below into Script Editor's window and save as an application.
do shell script "/usr/bin/defaults write com.apple.iWeb iWebDefaultsDocumentPath -boolean no"delay 1
tell application "iWeb" to activate
You can download an already compiled version with this link: iWeb Switch Domain.
Just launch the application, find and select the domain file in your Home/Library/Application Support/iWeb folder that you want to open and it will open with iWeb. It modifies the iWeb preference file each time it's launched so one can switch between domain files.
WARNING: iWeb Switch Domain will overwrite an existing Domain.sites2 file if you select to create a new domain in the same folder. So rename your domain files once they've been created to something other than the default name.

I'm using PSCS6 on a 500GB SSD. Do I still reach a better performance by adding a scratch disk?

Hi,
OS X and PS are running on a 500GB SSD. Since I'm working with a MacBook Pro with 8GB RAM, I'm wondering if an external scratch disk would help to reach a better performance? The files, I'm working on, are usually between 300MB and 900MB.
I appreciate your suggestions.
Thanks,
Daniel

Photoshop PC version anyway seem to fill up the first scratch disk before allocating space from any other scratch disk. So if you has sufficient free space on your scratch SSD you don't need more scratch disk for Photoshop. A raid 0 of ssd will stripe data across ssd devices and my improve performance.

Macbook Pro with Dual hard drives. Scratch Disk, Memory 64bit, Raid, Set Up Questions.

Hello, this is my first post.
I just upgraded from the original 2006 17" Macbook Pro to a refurbished 13" Macbook Pro 2.53GHZ 4GB Ram (2009 model).
I bought the MCE Tech Optibay and installed it (if you dont know anything about it, ask me, its amazing.) So now I have 2x 500GB 7200RPM Seagate hard drives installed.
I am running Snow Leopard, CS3, Lightroom 1.4.
I have the main hard drive set up with Snow Leopard and all the Applications. I keep all my files on external firewire 800 drives, except files I am currently working on.
The second hard drive is set up as a scratch disk for Photoshop CS3 and that is it.
I am looking to upgrade to CS5 and Lightroom 3 here within this month or so. Or if I get anxious, tomorrow, haha.
I want to know the best setup I can do with my current set up with CS3 and for my future setup with CS5.
Any info will appreciated.
-Would some kind of raid set up with my internal drives be better? How does raid work with scratch disks?
-If I upgrade to 8GB memory in my macbook pro, would I even see a difference in performance if I didn't have a scratch disk? Since CS5 and Snow Leopard can use more memory in 64bit.
I think thats all I have on my brain right now. I may have more questions, or I can guarantee I will have more later.
Thanks alot.

First the scratch. Like you said, most everyone has a different take on scratch discs but I'd guess you're wasting one heck of a lot of hard drive space using all 500 GB for Scratch, did I read that right? If I did read it correctly YES, partition it and get some use out of it!!
I've got a unibody MBP 2.93GHz, OS 10.5.8, CS3 & PS 5 (running in 32bit mode), and 8 gigs of ram. I've partitioned the one 300 GB drive so 50GB is scratch, the other partition is for OS, & Apps, and documents (images).
I use LR 2 first than export to PS 5 to finish up. My photos get to be 300MB to 500MB in size and both versions of PS work on this setup just fine. Using PS 5 in 64 bit mode is faster opening files but NON of my plugin's are 64 bit yet, that's why I'm still stuck in 32 bit mode.
Not knowing what size or kind of files you work on makes giving advice a bit tough but try setting the status indicator (don't know the right name for it) in the bottom left corner of any PS open file to "Efficiency" and watch what happens when you process your files. I rarely see mine drop below 90%, I've got the usable RAM in PS Prefs set to it's max suggested, cut way back on History and Cache.
Can't wait for NIK and others to offer their plugin in 64 bit, later this year is what I was told.
There used to be an old "rule of thumb" with old version of PS about Scratch disc size. I don't remember exactly but it may have been 3 to 5 times the size of your biggest file??
Good luck, Alan
