I don't know the difference in seconds, my Finder only shows the time exact to the minute. ... View more

Thanks again for your helpful replies, Planet Frog! But I think I've found what causes the message (for me): since I decided to not just click the message away with "save anyway" and look what the Finder says about the file I want to save, I noticed there's always only, and exactly, a ONE MINUTE difference between the created and changed time / last opened time. That is (in my stupid-user theory!) because I like to save new versions of the document I work on *a lot*, so I can easily go back when I mess something up. I think most people work like that. My documents are usually large with hundreds of layers etc, so when I go to "Save as" it takes a few seconds until the document is saved, and this seems to result in different timestamps, if a new minute begins during the saving process. Next time I hit "Save", I get the message. Of course I have no idea if this makes any sense, maybe Chris could be of help here? ... View more

Thanks for your replies! I managed to reduce the HD working time a little bit by adjusting the Spotlight settings. Your answer, Planet Frog, has made me scared - I'm on a 5 years old Macbook Pro, and maybe my HD really decided it's time to say good-bye, slowly but surely… I don't have a separate scratch partition and I'm afraid to mess with these things right now. But for my next computer (or next HD…), I will stick to your valuable advice! The disk utility says that the SMART status is ok., so I just keep my fingers crossed and hope that the Time Machine will work when the final hour has come… The last big adjustment I did was putting new RAM (which seems to work fine) in my computer and upgrading to Snow Leo, about half a year ago. I *think* I get the Photoshop message only since a few weeks, but I could be wrong. I've been underwhelmed by Snow Leo and wouldn't be surprised at all if it turns out to be the guilty one. Since the upgrade, I experience all kinds of funny behaviour (no automatic hibernation mode, unstable WiFi, the always busy HD, etc.) and I'm convinced that Photoshop is only the indicator of something going wrong underneath. ...

Hello, just wanted to chime in and say I've encountered this annoying behavior since a few weeks. I can't imagine what has caused this bug, no spectacular changes to my system (at least none that I'm aware of). This thread hasn't been very enlightening for me so far… I'm using CS5 and Snow Leo, no extensions, no Suitcase, Dropbox, Spotify, whatever else has come up as possible error sources. What I ask myself now: could these messages be a sign of a damaged or dying hard drive? Because my hard drive seems to "working" more than necessary (by that I mean the reading/writing noise) and I believe I always get the message while the HD is busy. Oh, and also when the interval between saving the document is rather short, like less than 2 minutes or so. ... View more
