Your disk copy of image was changed since last opened or saved (Mac OS)

Jan 3, 2012 12:33 PM

I am  occasionally getting a message that "the disk copy of image  was changed since the file was last opened or saved". The OS is 10.6.6 and I am using CS5. It happens on no specific file. All of my files are pretty big. The current one that this is happening on is a psb that is 3.26 G unflattened. I have from  ignorance always ignored the message and saved anyway. I have never detected any damage or discernible changes to the files after ignoring the warning, but after searching Adobe forum and reading a thread about this happening in CS4, I guess I should be more cautious and do a save as and change the file name. I started this thread because no one has reported the issue happening in CS5.

 

The files were all given to me by ftp as either psd, tiff or camera raw files.  I work on duplicates of the originals in no other program but photoshop and opened and closed the files a few times before getting the message about the disk copy being changed. All of my files are saved to an internal harddrive and  backed up on a time capsule device. I am on a network, but am the sole user of the network. The files are  worked on and saved to an internal hard drive on the same computer. They are never opened on another computer which is usually turned off. I am running no virus protection software except what ever is native to the OS. The only other applications I am running when getting this message are safari, mail and sometimes bridge.

 

Why am I getting this message and what is causing changes (that I can't detect) to the disk copy?

    The mesage means what it says:  something outside of Photoshop has modified your file on disk since the time that Photoshop saved the file.

     

    We don't know what might be changing them -- just that the OS returns a different modification time for the file than what it was when Photoshop saved the file.

    Just want to let you know that I have been receiving this message lately, also. I'm in CS4 on an Intel iMac. I've been ignoring it, too :~:

    First you need to figure out what is changing the file outside of Photoshop....

     

    Without knowing what sort of changes are being made, I have no idea if you should load the new file, save over it, or what.

    I just wanted to chime in that I have the same problem.  It seems to only happen if there is a significant delay between the current time and the last time it was saved.  I know that there is nothing on my computer modifying my photoshop files, except Photoshop.  I do have Spotlight enabled, but I don't think Spotlight modifies files.

     

    10.6.7, Photoshop 12.0.4 x64

    Well, something on your computer outside of Photoshop is changing the time/date stamp on the file or the size of the file after Photoshop last opened or saved the file.

     

    Since most people don't have this problem, I'd look for a haxie or system utility that might be messing with files, or with the Finder.

    Most other people are not seeing this.

    And I've got TimeMachine running on my office and home systems, plus DropBox, and am not seeing it.

     

    So, I would suspect something else -- but it is possible that this is caused by a bug in something common (Finder, SpotLight, etc.) that only triggers on some systems.

    I don't know what to suspect.

     

    What have you installed on your system beyond the OS and Photoshop?

     

    Most haxies are located in ~/Library/Contextual Menu Items/

    or ~/Library/Internet Plug-Ins/

    Other than Dropbox and the OS, I don't see anything obvious.

     

    But, again, there is something different about your system from most other people's systems.  You need to figure out what that is.

    Haxies: I just don't know where else they might be installed.  But there are so many places you can add system libraries and utilities, I'm not sure what to tell you to look for.

     

    Almost any utility, driver, or other application might be involved in some way.

     

    All we know is that something on your system is modifying the file time/date stamp after Photoshop opened or saved the file.  And we know that whatever the cause is, it is not present on most other users' systems.

    >and sometimes bridge.

     

    since bridge will change the modification date when adding stars or labels to a file, and these are larger PSB files.... is there any chance that there's a delay in writing the metadata within Bridge that causes the file to be out of sync within PS?

     

    I really don't have a clue........it's just a thought

    Hi.

     

    I just started to have exact same problem.

    Upgraded a Mac Pro from Leopard to SNow Leopard and then Adobe Suite CS5 to CS5.5 and now my Photoshop CS5 keeps

    giving me this damn error everytime i work on a image

    The image is not located on the main drive, i work on a 3 person network and it have been working just fine for over 5 years now.

    Just after the Snow leo and Suite CS5.5 upgrade the thing started.

    What to do next ? I have nothing running accept for some Nik and OnOne photoshop plugins. Thats it. No extra app ad-ons or

    programs what modifies anything. One thing to add here is. It only happen when working over network. Not on the local disk.

    And the computer where the files are located are identical so no haxial or anything running there aswell.

     

     

     

    btw i changed the photoshop settings to "Auto update open documents" and now i dont see it anymore but now i'm afraid editing i do

    on the pictures is not added after i close the picture.

    I remember back in time when this message came

    "the disk copy of xxx.tif was changed since you last opened or saved it"

    that all the stuff i had done on the picture was gone when reopen the image

    Anyone know if it is safe to use the "auto update open documents" ?

    Hi again.

     

    Nope. It was not because of Spotlight sadly.

     

    I still have the problem everythime i don't safe the image more than 5 min. If i save, save and save, it dosent happen.

    But if i wait 5-10 min before. It does it. This sucks because it makes the work take longer and as i said earlyer.

    Sometimes the work you did is not saved to the image

     

    We need to find out what this is. If its only with Mac OS X 10.6.6 or with any Mac OS X build ?

    P.s i now see its not only a 10.6.6 problem. One user are on 10.6.7..Damn
    I have checked all over and we never installed any small apps/haxie or anything that runs that can change the files.
    And it is on 3 Mac pro computers all with Photoshop CS5 and 10.6.6 ????

    Hi caligula1

     

     

    Please tell me exactly how you cleared your preffrenses ? if you did it manually or the Adobe way.

    I think there is a keyboard combination there clears everything ?

     

    But please let me know what you did and i will try it too

     

    Thx

    Really, damn

    I wonder what it can be. I'm 100% sure its nothing running in the background changing the files in my workflow.

    I checked everything and its funny because it is the same on 3 Mac Pro here ???

    So it must be a bug some where in Adobe's files/apps/etc

    Some combination of files, setup or what ever making the error come up.

    I never had it before i upgraded to 10.6.x Before all Mac Pro was running 10.5.8 with PS CS4 and it worked alright.

    Then i upgraded all our Mac's to the latest to get the 64bit feature and PS CS5 and even the newer CS5.5

    And then it started and its also with the newest PS from CS5.5

     

    First i thought i found the problem because i saw a post at Extensis forum about the Suitcase FM core and Fontsense

    extension for Photoshop and i deleted the extension from photoshop plugin folder and i was happy at first but then again.

    It came back after a wile.. Sucks. Not that.

     

    I wonder if its really because PS thinks the image was changed. I know it suppose to be that way but in our situation it is

    something else. A bug ofcause and i have been trying to figure this out the last 3 days and even yesterday i used 7 hours

    in a row to find a solution but i never found it.

    I really hope we can find a way other than reinstalling Mac OS X and Photoshop. I do think if we formatted the drive and

    started all over it would help but i don't want to do that because it will take me for ever to set up from scratch, yarggg

     

    What do you think ? Do you have any idea whats so ever what could course this ? any ideas

    And yet the vast majority of other users don't see this problem.  And in theory, this problem can only happen due to external applications, or a bug in the OS.

     

    So my guess is that it is something you have installed or changed on your systems.

     

    Have you tried completely removing the Extensis font software (not just the plugin)?  Extensis has already said that their software modifies PSD files after they are saved (yes, lame, I know).

    No, as long as the Extensis software is running, it is a suspect.

     

    And your list of installed applications doesn't include drivers or utilities like the Extensis software.

    OS X's Activity Monitor (look in Utilities folder) would best convey what is running on your Mac.

    Also recognize that there are more processes than what are running in your own user space. "All processes" may be selected in Activity Monitor.

    Nothing there jumps out at me as being a problem.

     

    Is there any chance that you are saving inside a Dropbox folder?

    No, documents can't change anything by themselves.

     

    I didn't see Extensis software in activity monitor - but I don't know exactly what to look for, either.

    Hi.

     

     

    Extensis Suitcase is not installed. Its a startup file called FM Core that runs in the background to handle font activation but thats not running

    on caligula1 system. It is on mine so now i know its nothing to do with that. It cant be now.

    I did try turn of the Extensis Suitcase extension auto program but that didn't help for me either.

    So what is left would be a OS X bug or something else tricking Photoshop to do what it does.

    I have been trying to find the solution the last couple of days but coulden so i guess the only way to get rid of this thing would be to do a fresh

    install and that i mean, new fresh OS X and Adobe sadly.

    It gotta be a bug some where ?

    I have a iMac 27 at home also with the same setup as my work Mac pro but i dont have the problem there. One thing i wanted to check and ask

    about was. My PS work is over network, a 3 person network. Files are stored on Mac 1 and me and another person work on the files from Mac 2

    and 3 so could it be something that happen because of the network ? and just to mention. All 3 Mac Pro have 100% same setup.

    Yes, it could be the network or something on the file server.

     

    Does this ever happen to files stored only on the local disk?

    I have been seeing this both on my Laptop (one harddirve) and on several computers attached to servers (when working off of the local disk). I've only seen this with CS5, but it may have to do with some Apple change. I don't remember with which version of OS10.6 I first had this happen.

     

    Like most posters I've been ignoring it since I know the file I am working on is absolutely the one I want to save. So far I've never had a problem with a file afterwards. From this thread I'm not sure if it's something I should be more concerned about. I wouldn't be surprised if it's a more widespread occurrence than Adobe thinks. Like most users I assumed it was some change in either PS or OSX causing a message I'd never seen before. I didn't take the time to deal with a little message that ignoring didn't hurt, but now that I see this thread I wanted to chime in.

     

    It seems to happen with files that have been open a long time between changes-- for example, if I leave a file open (and freshly saved) for several hours and then return to working on it.

    If it were really widespread, we would have seen it ourselves, or heard about it from more customers.

    So far, it sounds like less than a dozen people are seeing the problem.

     

    There is still something different about those systems, and we need to figure out what is different -- so you can change it, or so we can reproduce the problem (and find the root cause).

    just curious because I've always dismissed this message when opening a SmartObject in AI:

     

    "PDF Modication Detected: This document has been modified outside of Adobe Illustrator.....how do you want to proceed?  discard or keep changes."

     

    is this normal or a similar issue?

     

    thx
