Aperture corrupting images during editing

Hello,

Starting a few days ago, aperture started corrupting images during editing. This was normally at the time of my fist cut, going through doing simple straighten and croping. Sometimes it would happen when doing a small lighten or darken of the exposure. I purchased a new MacBook Pro about a month ago but this only started happening this week. No OS or Aperture upgrades this week. I did have a crash earlier this week and after the crash my Spotlight re-indexed my computer. I updated QuickSilver this week and Awaken. I tried quiting both QS and Awaken but problem still happens. The real scary thing is I usally have to go back and re-import the raw CR2 image to fix the problem, doing an update from master or resetting all adjustments does not fix the problem. Below is an example of an image with the problem. This is a Version Export of a corrupted image, as you can see the cor Can I get any help?

MacBook Pro, Mac OS X (10.6.8)

I wanted to add to this as well. I have tried restaring Aperture and fixing my library but this does not seem to help. I have multiple libraries and created new libraries for each major project so the example above is in a completely new library.

Are you by any chance running out of space on your system drive?

I am using about 300GB of a 500GB drive. So I should have plenty of space for Aperture to work with.

Is your version of Aperture completely up-to-date? (Just checking for the obvious.)

Aperture 3.1.2, Digital Camera Raw 3.7.1.

There were reports of problems like this with earlier versions of Aperture 3. I haven't seen one in a while, though.

Btw, QS always -- perhaps undeservedly -- raises a flag for me. Loved it; never had a stable system when I used it; purchased LaunchBar.

Just double check to be sure and yes, I am on the current versions you are listing above. I tried something. I exported the "Master" and took a look at the CR2 file with Preview and it shows the corruption. I thought Aperture did not apply changes to the master? Maybe my RAW files are getting corrupted on import of something? I am scared at this point to keep using Aperture for a chance of loosing images.

What camera is this from? Preview would use the same RAW decoding as Aperture and iPhoto. What is the size of the RAW export file? If it would email, or you have some place where I could download it from, I can check it with Photoshop CS5 for you.

I am not sure, that the problem is unique to raw images. I occasionally see the very same effects (since April) when I crop or straighten a jpg-image, even images that are many years old. The previews do look just fine, but when I display the image in full screen mode, then some portions seem to be corrupted like above, and they stay corrupted in any external editor I try.

Aperture 3.1.2, Mac OS X 10.6.8

Well my new MBP hard drive crashed hard last night. Ended up reformating and trying to install the OS again but OS install fails. I am wondering if the issue might have been a bad hard drive that caused the image problems. I guess if it is reading/writting to disk a lot when I am doing edits and the disk is bad I might get corrupted data... but just not sure. I will be in the mac store tonight to get the drive replaced, we will see if they thing this could be the issue.

I had an issue with what I thought was Aperture after the 10.6.8 update to OS. Then all of a sudden the two volumes on the drive with the Aperture Library (one volume was exclusively the Aperture Library) disappeared from the Desktop. But after a restart and after running Disk Verification, I found the only errors were on the volume on the drive that were unrelated to Aperture, and that those errors would not be repaired.

Placing the drive outside the Mac Pro, in a BlacX USB drive I was able to copy everything but one or two items, and the drive will likely work after I reformat it.

So, an issue with the directory on the same drive as the Aperture Library can cause problems that look like they are related to Aperture, but may not be. In my case neither volume was the boot volume.

As I read down this thread, I started thinking bad hard drive and was going to suggest you try it on an external drive. The only time I've seen this, it turned out to be the memory card, but I dismissed that conclusion when you said it was happening with older files.

Hello,

I went into the apple store and they did diagnostics and saw no hardware issues. After running my mac in the store awhile I was able to show them the error and crashing software. They replaced my laptop with a new one. When I got home I migrated my apps back but not my settings as recommeneded by the genius. After using it for a few hours I started getting the corrupted images again. I am at a loss. I have a massive job I am working on and almost a week behind schedule trying to fix this problem. Anyone have any other ideas? I am going to setup another genius appointment this weekend to discussion the issue as not a hardware issue but an Aperture issue.

Oh, I was hopeful last night as there was an update to Aperture but after the update same issue still happening. I am thinking of doing a complete uninstall of Aperture just not sure that will help with anything.

Where is the Aperture Library? It could take hours to copy a large library, and I see no indication of how that was done? If the Library or Referenced Masters are on another drive, that is the drive you need to be checking.

On my Mac Book Pro I have noticed that those errors only occur after working several hours. That could mean that it is a thermal problem with the CPU (my Laptop get really hot) or there is a memory problem related to the CPU.

Either way, my pictures are safe as long as I reboot every two hours and let the Laptop cool down. But this is certainly no solution if you ar working on a tight schedule. Could you borrow a replacement laptop from the apple store and work with it for two days or so, just to exclude any hardware issues for good?

Ernie Stamper:

The Aperture Libraries are on the local drive. I do have an external Firewire drive I can use to test your theory but since I recently replaced the whole laptop at the Apple store so I am thinking it is not hardware related but one of three things: an Aperture bug, my configuration, or memory (see more on memory below).

leonieDF:

I don't think it is related to a hardware issue unless it is memory. I took the laptop into the mac store because I was having a hardware issue not discussed in this thread. The laptop was completely replaced except for the memory since I purchased 8GB of memory after the computer was purchased. I put the 8GB memory back into the new laptop. If this is a memory problem it is not showing up in diagnostics. I am planning on doing two things this weekend. First thing is putting back in the original apply memory and testing. If I still get the issue I am going to do a complete uninstall of Aperture and re-install maybe something in my settings/libaries are corrupted. I am reaching for straws at this point. I might also try a complete reformat and only install Aperture and test to see if something else installed might be causing this, but I can't think of what it would be.

Have you tried importing with any other app to see if you get the same results?

Have you tried importing into iPhoto or Image Capture?

Just some more steps on narrowing down whether it's an Aperture issue or System.
