Scratch Disck Question

I have a 150 Raptor 100000rpm 16 cache
500gb 7200rpm 16 cache
and 1Tgb 7200 rpm 32 cache
My questions wich one I should use as my main hard drive, and wich one I should use as my Photoshop Scratch Disck ?
Thinking to have better performance with photoshop CS3.
My operating system,: windows Home Premiun 64bit, Q6600 2.4, 8gb ram,
Thanks in advance--

> unless you want the entire 150G to be scratch.
Nothing wrong with that. I have a 25% full 160 GB data disk as primary scratch and PS uses what it wants.
I don't like partitions!

Scratch Disc Questions using Firewire External Drive & Imac

Hello. I've read through the existing questions regarding scratch disc and Photoshop, yet can't seem to find an answer to my questions. I would greatly appreciate any tips/advice. Here is my setup and situation:
I am running an iMac with a 2.16 intel core 2 duo processor, 3 GB memory, and running OS X version 10.6.4. I am currently using versions cs3 and cs4 of Photoshop, but plan to upgrade to cs5 soon.
The problem I am having is when running Photoshop, my computer becomes very slow. After reading about possible reasons, I came across a couple of sources (including Adobe themeselves) mentioning that the scratch disc should be a designated drive seperate from the drive containing the operating system. Since I am using an iMac that only allows for one internal drive, my only apparent option seems to be an external drive.
Many people say don't use an external drive, but if you are going to; use an eSATA or firewire. The imac does have firewire 800 capabilities. Should I consider this?
Now I'm wondering if it's a bad idea to purchase a macbook for my next computer (what I wanted to do) because it will also only have one drive, not allowing for a seperate drive for the scratch disc. Any thoughts? I've read around the net but haven't found any definitive answers.

Designer,
Photoshop benefits greatly from having a scratch disk on a separate physical drive, not on the boot disk or on another partition of the boot disk. It's almost not worth connecting via Firewire 400 because the transfer limitations don't allow much performance improvement. But using a Firewire 800 connection gives excellent performance.
Running Photoshop on a one-drive machine is a little frustrating due to the performance hit without the separate scratch drive.

Photoshop scratch disk question

Hi All,
I do a lot of work with photoshop elements, and currently have an external drive with a 2GB partion as my scratch disk - connected via firewire.
However I am beginning to find this set up a little annoying as it means I am stuck to one location unable to move when using photoshop.
I was thinking about partioning the internal hard drive on my PB instead and so having the scratch disk available wherever and also the transfer speed would be by the Gb instead of 400Mb. (am I right?)
Is it a good idea to partion a hard drive on a portable? is it worth all the hassle of reinstalling and also has anyone had any problems after partioning? like battery life decreasing?
Thanks in advance,
Naj

you seem have to put this question in the software session but fine. well, actually, you don't need to specifically partition you drive for photoshop and just let it choose your start-up disk or other connected drive you choose. but, for external drive, you have to connect while you start up you system. if not, your ps will always switch back to your start-up disk when you start your ps.

Scratch Disk Question

In the past I have had 10 GB partitions of the main hard drive to use exclusively for a scratch disk for Photoshop and all the other Adobe Suite apps because I had heard it wasn't a good idea to have the scratch drive the same as your main hard drive.
Just recently upgraded to an iMac (a nice, new, white one with the high quality matte screen) which has a 250 GB internal drive. I didn't bother to repartition this one and have been using it as my scratch & main disk for the last 2 months. Which means the system is on this drive and I am opening and saving to it regularly.
My question is, would it be worth it to create a separate partition just for a scratch disk? Does it really make that much of a difference? I haven't noticed any problems up until now but was wondering about it.
As you can see below I have a 2.16 Core 2 Duo with 3 GB of ram, HD currently has 108.3 GB available, 124.2 GB used. I mainly use Adobe CS3; Illustrator, Photoshop & InDesign always open and in constant use and switching between them.
So should I repartition for a dedicated scratch disk or is it not necessary? Well, obviously it's not necessary since I've been working fine without it for 2 months, but will it improve performance of the Adobe apps and/or prevent possible directory corruption? And if I should how big should it be?

Hi! If it's doing what you want I wouldn't mess with it. The biggest bottleneck is probably if you were at a near full disk situation. As long as you keep 15-20% of free space you probably won't have problems. One other thing you can consider. You should have a bootable clone backup for emergencies and using an external firewire drive works good for that so if you get one you could always partition it to use as a scratch disk as well as a bootable backup clone. The internal disk speed is going to be faster that firewire so as long as the setup you are using is working well I'd stick with it but give serious consideration to a bootable backup solution. Tom

Canon camcorder + scratch disk questions

I have a Canon Optura 50 (I now know that was not the best choice!). But, given what I have and I can't buy a new camcorder for a while, I would like some advice and clarification.
I have been following the thread on dropped frames and the do's and don'ts of internal vs external hard drives (http://discussions.apple.com/thread.jspa?forumID=936&threadID=680582). The consensus seems to be that (a) it is not a good idea to use the internal drive as the scratch disc, and (b) best to use an external FW drive and daisy chain the camera to FW drive to computer.
With the Canon I take it I cannot daisy chain it due to it's FW hardware quirks of not liking anything else on the FW bus at the same time as video capture, correct?
Am I going to run into major problems with my internal drive, since I use it as the scratch disk? I capture to the internal, and then move all the files to the external for editing in FCE.
Is there anything else I should know or do? I have created several projects in FCE, with success. I am slowly learning more as I go, and this forum has been a great help.

With the Canon I take it I cannot daisy chain it due to it's FW hardware quirks of not liking anything else on the FW bus at the same time as video capture, correct?
I have my Canon daisy chained through my external HD with no problems. Ever. So I am forced to believe either I have been blessed with enternal luck (knock on woodcrest) or convince myself the consensus that there is a specific problem with Canon cameras being daisy-chained has been the direct effect of pure coincidence and speculation. One will truly never know if a specific set-up will work until they try it out for themselves so go ahead and daisy chain that Canon away and see if you have problems.
And as far as using an external disk as your HD goes...
If you have the FC Express User Maual, take a look at Chapter 12 titled "Determining Your Hard Disk Storage Options" starting on page 153. If you don't have the manual feel free to check it out online here on Apple's website. Be aware it's a 26.5 MB link so it might take awhile to load but I'll highlight the juicy stuff for ya:
The manual states:
"By default, Final Cut Express HD uses the hard disk on which the application is installed
as your scratch disk to store captured and render files. Ideally, you should use a hard
disk other than your main system disk as your scratch disk."
It goes on to mention:
"The data rate of the video you capture depends on the format of the source video and
the codec you use for capture. The data rate for DV and HDV is 3.6 MB/sec.: Whatever
disk drive technology you decide to use, your storage disk’s sustained transfer speed
must be fast enough to keep up with the data rate."
The MBP can have a 7200 drive installed in it and that's not really the point. The point is it's just not reasonable to think that ONE HD, even if it's a 10,000 Raptor, can read the information to run the Operating System, Application, AND read your video/audio data all at once without expecting hiccups. You need your System drive to run your OS and Apps. and your seperate Scratch Disk for your Media (not a partition of your System Drive). Simple as that.
Not saying the other way isn't possible, it's just not recommended. If Apple doesn't recommend it then I won't regardless of status.

Photoshop CS4 Scratch Disk question

i've asked questions about this topic before, but did not quiet get the answer i was looking for.
First: How much hard drive space should be allocated to photoshop? We are working with files at times exceeding 6GB. We have 32GB of RAM and a few hard drives, internal and external.
Second: the size of my Documents folder is no more than 250gb and the capacity of the system hard drive is 500. What else could possibly take up so much room? the programs take up about 50gb so im left with 200 missing GB?
Thank you for your attention.

Turn off system restore or at least manually delete older restore points and reduce the number of states to store. Windows will create restore points after every install and also in regular intervals without you doing anything. Even if they are incremental, they are taking up oodles of space. The hibernation cache is usually the exact size of your system directory + swap file + RAM amount, so if you have a lot of RAM and a large swap file, it wil lbe pretty large, too. It can however be eliminated by simply turning off the hibernation in the energy management options. For further cleanup, use Windows' own Disk Cleanup Utility or tools like CCleaner.

Scratch Disk Questions

Only pagefile, scratch/renders, and program files on this drive? Any reason not to do some file storage on this drive, too? Or what about other programs that never run simultaneously with editing apps?
Is it acceptable to have my main media storage drives in a RAID array, but use a single unraided SATA drive for scratch? Or should one move the scratch disk from a single drive to RAID in these circumstances?

Keep in mind that the Velociraptor has only 16 MB cache, whereas a 1 TB disk has 32 MB cache. Also keep in mind that on a 150 GB disk 100 GB of data amounts to a fill rate of around 70%, while on a 1 TB disk that would only amount to 10% fill rate. Comparing both disks when empty, yes, the Velociraptor is faster, but when filled up to 70% is may well be slower than a 1 TB disk filled to 10%.
Look at these charts:
The spikes are caused by the cache being depleted. With 100 GB data on the disk, the sequential read speed is around 100 MB/s
Now look at the graph from a 1 TB disk:
With the same 100 GB data on this disk the sequential read speed is around 115 MB/s
Now look at the graph for a 2 disk raid0 array with 2 x 1 TB disks:
With up to 900 GB of data the sequential read speed stays at around 200 GB/s.
And the last one, a 12 x 1 TB disk raid30 array shows these figures:
Across the board this delivers a sequential read speed of over 800 MB/s (average 853 MB/s) and no deterioration with increasing fill rates.
Although these graphs only indicate sequential read speeds, the same pattern applies to write speeds.

HELP! scratch drives questions

I am working on a video project with final cut pro 4 and I just bought a LACIE HD with 250GB on it and when I try to log and capture it says the scratch disks are full.
I don't know what to do and this project is really important so please help me
thank you

first and formost, reformat the drive to Mac OS Extended - Journalling Off
it is probably set-up for windows (MS-DOS) and this will cause all sorts of issues.
Go to: \Applications\Disk Utility
Select your new drive from the list on the left side and ERASE from the bar running across the top of the right side.
Set the Volume Format to Mac OS Extended , give the drive a useful NAME and click ERASE.
PLEASE NOTE: any information, files etc on the drive will be blown out.
Once the drive is properly formatted, try again.
Good luck.

A few questions before I buy a new iMac/Mac mini and sign up for Creative Cloud.

Hello Everyone,
I am looking to purchase a new Apple computer and sign up for Creative Cloud within the next week and I have a few questions that should be answered before I proceed.
My wife and I own a business and we will be using the CS6 apps to create brochures, Constant Contact mailings, product package inserts, edit product photography for print and web use, and short HD how-to videos. We are not graphics professionals or power users and wont be doing anything too complicated.
Any help and answers will be greatly appreciated.
I will start with the hardware questions first:
I am trying to decide between the iMac and the Mac mini.
The iMac is a 2.7Ghz Quad-core Intel core i5 and comes with 4GB of memory that is expandable to 16GB, which I will do for sure. It comes with a Radeon HD 6770M graphics card with 512MB of GDDR5 memory(not upgradable), and a 1TB HDD that runs at 7200RPM. This unit meets the specs required.
The 2.5Ghz Mac Mini comes with 4GB of memory that is expandable to 8GB, I will also do this. It has a Radeon HD 6630M graphics card with 256MB of GDDR5 memory(not upgradable), and a 500GB HDD that runs at 5400RPM. This unit meets all the spec(I think) except for the speed of the HDD.
Question: Will the mini run the software without too much of an issue considering the speed of the HDD?
Question: Will the iMac run the software significantly better to justify the price difference?
I already have 1 mini(purchased 4 months ago, with the same specs listed above) and will be purchasing a second computer for my wifes desk. If the mini will run CS6 fine, that is great and we can save a few bucks. If my mini will not run CS6 well, I will get the iMac for her desk as she will be doing the bulk of the work in that regard anyway.
Now a couple of software questions.
After reading hundreds of reviews and forum posts over the last few days I have seen many people having this or that issue. It seems to me that most of the issues are because of upgrades from Lion to Mountian Lion after installing CS6 first or trying to open CS3,4,5 files in CS6.
If you want to know what issues have me concerned take a look at just this one forum:
http://blogs.adobe.com/jnack/2012/07/adobe-cs-apps-mountain-lion-no-known-issues.html
Similar issues are discussed in the Apple forums as well as many other places around the web.
I am not a computer professional but I know enough to maintain my systems and keep them running smoothly.
We do not have any Adobe software installed on my mini and will not be opening any files from previous versions of Adobe product in the new CS6 software. These will be a clean installs on pristine systems running fully updated Mountian Lion OS's on both machines and creating new files from scratch.
Question: Should I be expecting any issues like the ones I have read in the forums and blogs or are these just the normal things that happen when upgrading to new software with multiple hardware configurations?
My feeling is that we will not be having too much of a problem due to the clean installs and no files from previous versions.
Next up, the Creative Cloud(CC) FAQ states that you can install on 2 machines but can't open stuff at the same time.
Question: Does this mean we can't be using any CS6 apps at the same time or just not using the same app at the same time?
Example: PS and PS on both machines at same time = No, PS on one and Dreamweaver on the other at the same time=Yes?
The CC FAQ page says Adobe will add Lightroom 4 later in 2012 while the main CC page lists it as available now.
Question: Which is true?
My mini is registered to me, with my name, iTunes account, Apple ID etc.
Question: Do I need to do the initial set-up of the new machine with all my information to ensure the CS6 suite works on both machines? Do the computers need to be registered(as far as Apple configuration is concerned) to same person for them to work on one CC account or can I install CS6 on any 2 machines regardless of how they were initially set-up?
This may seem like a silly question but I want to avoid any problems before they happen.
Well, those are all of my questions at the moment. To anyone who made it this far in my looooong post, Thank You so much for your time. I appreciate your expertise and knowledge and hope that you can help me make this decision.
Cheers,
Alex Bogdan

Alex,
I'll try and answer your questions as best I can.
Qn 1 Which Mac.
Ans:- As I understand it both units will run Adobe CS6.
          Which one really depends on what you wand from CS6. If you are looking for high end demand and performance, then I would go for the IMac
          Your Specs for the Imac are right. However if you buy your IMac straight from Apple there are even higher specs.
          You can get:-
                              3.4 GHz i7 processor rather than the i5
                               2GB video card as opposed to a 1Gb video card.
                               Of course such a model will cost you more.
          In the end it is needs compared with money to spend. That is only a decision you cam make.
Q2:- Will the higher cost for the Imac justify copst.
Ans:- Again it depends on what demands you intend to make on the hardware and software.
          But I note you have a business and if that businees expects to high demand and high speedy performance then I suspect the Imac would be more able to provide your needs.
          Again only you will know the answer to that.
Q3:- Questions about CS6 reliability
Ans:- I have been with Adobe for way over 10 years.
         Speaking, only for myself, it is the most reliable software on the market.
          It is true that if you look down this form, like any other and I am thinking about the Apple discussions forum, you will find numerous instances of problems.
          Again this is only my opinion, but although all these problems are real for the individuals:-
          First it is not clear why they have the problem e.g. what have they done or not done.
          Second, they are in the minority of the total users using the hardware / software.
          The only problem I am aware of with CS6 is Acrobat X. I understand it has been sorted Adobe, however it cost me so much work I have removed it from my system and reverted to Acrobat 9
          So what I am saying is that there are only two comapnies I rely 100% on: They are Adobe and Apple.
         So if you are happy with my opinion I would not worry about Adobe CS6
Qn 4:- CS6 0n 2 machines.
Ans:- Yes you will not be able to run the same program similtaneosly.
           I believe, if it is important that you do run the same program together, that you can acquire a further licience from Adobe to do that.
           You would need to contact Adobe about that.
Qn 5:- Lightroom 4
Ans:- Lightroom is now available as part of Creative Cloud.
Qn 6:- Set up for individual machines
Ans:- I do not believe you do. Once you have set up your Creative Cloud account you go to the apps site and download the apps for each machine.
          Each machine downloads the apps and your machine and the apps are registered by Adobe.
         Here is something that you may want to know:-
          Because I was so unhappy loosing all the Acrobat data with Acrobat X I ended up deleting Acrobat X
          However as far as Creative Cloud is concered Acrobat X is still on my machine.
          It is not a problem for me because I am happy with Acrobat 9, it fullfils my needs and has not crashed and lost me all my bookmarks.
          However here is the point:-
          Adobe, when there was a problem with Acrobat X requested that no-one deletes the application.
         Though I do not know for certain I believe registration of the apps you have with Creative Cloud are registered with Creative Cloud in their database. Therefore were you to delete an app, it will still be registered with Creative Cloud and you will not be able to download a further copy even though the app is no longer on your    machine.
          Therefore it maybe not a good idea to delete an app when you no longer have a use for it. If you want it back I suspect you will have to contact Adobe Support
Personal Comment:-
          It is true many unfortunately have had all sorts of problems, including me with Acrobat X.
          That said, Creative Cloud in my view has been a major advance in how Adobe delivers software. I have no regrets with signing up to Creative Cloud and I expect to remain with it.
Hope all of that goes some way to answering your questions.

MULTIPLE SCRATCH DISKS FOR THE SAME PROJECT

Hello... I have a quick scratch disc question:
I have project that is running too low on scratch disk space. Can I use my boot drive (that has FCP on it) as an alternate scratch disk for the same project? Or does one project have to have the same scratch disk?
Thanks!
- TEXASFLOOD

Hi Texasflood,
Having all the media in one place is preferable. Among other things when using multiple scratch disks you always have to make sure and double check that your logging bins are correctly set and that FCP is using the scratch disk you want.
What you could do is use Media manager to move the existing media to the new scratch disk with plenty of space (Media manager will reconnect all the media) and then capture your remaining 24GB in your new scratch disk.
Read about how to use Media Manager in the manual and checkout the paragraph in this linked article titled [Copying And Moving Projects|http://www.kenstone.net/fcphomepage/media_manager_fcp_4balis.html].
If you do use MM choose to copy and not move media, then for the piece of mind check first that everything is in place and working and only then delete the media in your older drive.

The perfect solution to scratches has been found!!

Get Over It!!!!
Ive had my 5G ipod for just over a month now. But with all the talk about scratches I was too afraid to touch in the first week. The result was that I was not enjoying it nor was I showing it off!!(which all 5G owners want to do!!)
So thought stuff this, I give up and im going to handle this thing as much as I want to.... The result could not be better.
I only use the case that was provided in the box. Now yes, you do get smudges on the back from handling it. But buy using the case it actually cleans it. The same goes for the front too.
All im saying is if everyone got over this issue I dont think it would not be as bad as it seems to be made out. (cant comment on nano, dont have one!) Sure there are one or two "faint" scratches, but you only see them if you look really hard in certain light.... Fark that, cant be bothered. Enjoy it and move on..

It is hard to "get over it" when the scratches in question impede the ability to view videos on the video ipod clearly. If it was just a music player, fine. But as a video device, I feel that it shouldn't scratch so easily. Take a nail and put a few deep ones in your TV screen, then take some coarse sandpaper and give it a few scuffs. Now try enjoying watching some shows.

General Error opening project won't go away

This is really bad. I'm supposed to show the current cut of my 15 minute movie tomorrow, but FCE HD 3.5.1 shows a General Error when I try to open my project. Not just my current project, but for all project files in my Autosave Vault and most project files in the Trash, too.
Here's my setup:
MacBook Pro, OS X 10.4.9
FCE HD 3.5.1
Project File stored locally
Scratch disk on an external Firewire hard disk
Nothing about my setup has changed since I started this project
All of a sudden this afternoon I got the dreaded "General Error."
Open my project with the media disk unmounted and unplugged: General Error
Trash the preferences folder and com.apple... file: General Error
Reinstall FCE HD 3.5.1: General Error
What else is there to do? Suggestions for how I can recover my project file without recreating it would be greatly appreciated! Thanks.
john

Tom,
Your suggestions in email to me didn't solve my problem, exactly, but got me thinking along the lines that did solve my problem. Thank-you very much.
Bottom line: this is probably a bad practice (I'm an iMovie veteran, but a FCE newbie), but I had media spread in three different places. Video was on the external firewire scratch disck, some jpeg's were copied to the same folder (or subfolder) as the project file, and (the killer) some files were left on a server computer on the LAN.
At some point I had disconnected from the server and FCE freaks out over that. Rather than giving a "missing media" alert like it does for a detached media or scratch disk, it gives an unhelpful "General error."
Lesson learned: when opening a project file, be sure you are connected to any and all servers on your LAN from which you may have imported media, like pictures.
Thanks, Tom!

Delete old and backed up archive log,

Hi all,
Am trying to modify our RMAN backup script to delete old and backed up archive logs off the disk.
We run daily Incremental L0 or L1 backups, with 3 daily archive log backups. Currently we delete archive logs as they are backed up (backup archivelog all delete input). However, we are considering leaving x days worth of archive logs on disk, just in case, quick restore is needed (e.g. tablespace media recovery etc. etc.)
For example,
We can delete archive logs old tha n x (where x=no_days depending on database) by,
delete archivelog until time 'sysdate-15';
We can also delete archive logs that have been backed up to disk by,
delete archivelog all backed up 1 times to disk;
Questions,
1) Why does 'backed up 1 times to disk' require the 'all' in the statement ?
2) Is there any way to combine the 2 statements ? (backed up 1 times and older than x days ?). Just being a bit extra cautious to ensure that we have everything backed up. In real-world shouldn't be a problem, as we will be alerted to any backup failures, but trying to cater for the very worst situation.
Thanks for your help and insight.

Hi,
Scratch the questions. Found the answer in another thread. Seems when I tried to combine the statements initally, I had a typo.
It is now working as expected.
Thanks and regards,

Noob - Setting up the buffer

Hello,
I'm not sure of the extent of my question but can anyone point me toward some sample files / tutorials that explain how to set up the buffer indicator? I presume this question could break off into multiple genre's of buffering (ie. progressive buffering, streaming, dynamic streaming, etc). I'm not sure where to start or if most of this is already built into the OSMF framework. If someone could suggest a starting point that'd be great! Thanks again!

Scratch my question about MediaPlayer.bytesLoaded, MediaPlayer.bytesTotal. I didn't realize I was using a streaming video when I needed a progressive video for those values to take proper effect. So, I understand how the progressive download progress works. Although, I have my download indicator updating on CURRENT_TIME_CHANGE, which, I'm sure is prolly not the best listener to update the buffer on. What listener should I attach to the progressive download function?
As for streaming videos, I understand your comments about MediaPlayer.bufferTime / MediaPlayer.bufferLength but again, what listener should be attached to the function? Also, I don't grasp how to apply this particular bit of code to the UI. Any suggestions would be great! Thanks again Brian.

Do over on an apple imap account

I want to delete a me.com imap account and let mail recreate it from scratch. Question is the saved mail folder that is "on my mac" will that be deleted, when I delete the account? If it is I can copy it to a folder on the me.com web app first.

No, only mailboxes associated with the account - and any messages they contain - will be deleted. If you have moved your mail to "On My Mac" mailboxes, those will not be deleted.
