I finished processing an image in Photoshop CS5.1 and saved it as a PS document of 29Mb. I then attempted to 'Save as' a jpg document to the desktop. The image 'froze' so I did a 'Force Quit' of PS and tried to reopen in PS which failed. Then tried to open the image in PS Elements which failed. Tried a Restart of the iMac (OS 10.9.5) but it failed so I Shut Down with the power button. After a few minutes I restarted and opened the image in PS but it was badly damaged. I tried to open it in PSE again and this time I got this message popping up: "This document has been damaged by a disk error. The most likely causes are a defective disk drive, a defective disk drive cable or incorrect peripheral cable termination. Some of the pixels in this document may be invalid." Well they certainly are with bands of yellow and blue pixels across what was a mono image. It's unusable but the question is what is the best action to take about the fault? I suspect an aspect of incompatibility between PS CS5.1 and Mavericks because I have been experiencing similar crashes since installing this OS. I don't want to update PS since it means a subscription to Adobe so perhaps will try PSE in future.
Hi Roy, and a Happy New Year to you. Your Photoshop CS5 version should be 12.0.4 (64 bits) which runs sweetly on Mavericks and Yosemite here, although it doesn't do very well visually with Retina screens.
Check this and, once you have sorted out the issues below, update (if those dismal folks at Adobe will let you). If you are running with too little RAM and/or hard disc space anything can get corrupted, and "pulling the plug" will make matters worse.
Once you have repaired permissions and checked (and repaired if necessary) your drive with Disk Utility, other first aid would be to clear out all those caches. To do this simply Restart, holding down the Shift Key until a progress indicator shows up. The words "Safe Boot" will appear somewhere depending on your OS X version, in red, and the Finder window lists will "ripple" (Mavericks) or your screen will get all kinds of terrifying flashing bands of colour on your screen (Yosemite). Sign in, wait for a while, then don't forget to restart normally. This Safe Boot will take quite some time, and the restart also, including your Applications if they maintain caches. Be patient and let it happen.
If this doesn't do the trick you may need to reinstall Photoshop and possibly OS X too, but you can try deleting the Photoshop Preference files. That means you will have to reset any non-standard prefs again.
If you have a clone available (you should have!) try starting from that to check for any better behaviour.
Let us know how you get on.
Happy New Year Euan and thanks for your reply. I will work on your suggestions later but can say that I am using Photoshop CS5 Extended version 12.1 x 64. Bfn, Roy
Have repaired permissions, done a 'Safe Boot' then a normal restart. All fairly 'painless' so for the damaged image of yesterday I reprocessed the original Raw file in Lightroom 5, finished off in Photoshop and filed it as a jpg. So far so good and I will continue with 'fingers crossed'. Many thanks again Euan.
