Unfortunately, I didn't know what the heck I was doing when I first started storing them on the external drive. I'm still trying to figure it out. Most of the images are in subfolders in the pictures folder, but some are not. This image was in a group that was in the pictures folder, but not in a subfolder. I was trying to move them into a subfolder when the error occurred. I organize my subfolders with their project names.
If you don't take care when choosing the location for referenced images, you can create some problems for yourself.
From an operational perspective 'Managed' images means Aperture will take care of the image file storage for you, 'Referenced' means you will take care of it yourself.
There are a number of things that may have happened but this is what I think is most likely:
If you shoot a lot of photos with the same brand of camera, eventually you'll end up with duplicate file names, for example two different files called DSC_1234.NEF. If you attempt to store these in the same folder yourself, worse case scenario is you may inadvertently overwite one of the files. If you use Aperture to relocate, you'll get one of the files with a new name of DSC_1234 (1).NEF.
So your first step is to figure out what these files really are. Are they duplicates, or are they different files with the same name, and do they each have a matching .JPG
Aperture has the tools to fix up the problem, but you need to confirm what the problem is first.
If you don't have many of the (1) files, it may be worth continuing your 'relocate' to subfolders - making sure your subfolder hierarchy doesn't cause duplicate names to be stored together. Then when everything else is stored correctly, address the problem images by moving them to where they should be, with the right name and the JPG/NEF pairs together.
You can then search for missing files in Aperture and use the 'Locate Referenced Images' to reconnect them with Aperture.
You're right, I do take a lot of pictures with the same camera. My computer is set up for 4 users. When I searched the file number in finder it came up with 4 jpeg & nef pairs corresponding to 3 images. All the pairs match up except for the problem image which is located on the external hard drive. One file is in the Pictures folder that contains the Aperture Library icon and the other file is in a subfolder in the Pictures folder. Before I tried to relocate originals of that problem image to the subfolder, the jpeg & nef pair were both just in the Pictures folder. Somehow, the relocate originals separated them.
Sorry meghan, I'm not following this:
All the pairs match up except for the problem image which is located on the external hard drive.
One file is in the Pictures folder that contains the Aperture Library icon
and the other file is in a subfolder in the Pictures folder.
The first statement says they are on an external drive.
The next two say they are in Your pictures folder (and a subfolder therein)
Or is your pictures folder on an external drive?
But either way, I'd just move both parts of the pair to where you want it to be. Then in Aperture, find that image and it should have a badge that says the file is not available. With the file selected, use 'File->Locate Referenced Files' to tell Aperture where you moved the image to.
The Pictures folder is located on the external hard drive. This is what I found in Finder:
the JPEG is in /Volumes/Audio/Pictures
the NEF is in /Volumes/Audio/Pictures/Hawaii 2010 - this is where I want the JPEG to be, how do I move it?
How do I locate missing files in Aperture?
ps the more I look into this, the more confused I get.
To move the JPEG, simply drag it in finder from it's current location in Pictures to the subfolder /Hawaii 2010.
That may be all you need to do. It depends on whether Aperture thinks the master is still in Pictures or if it thinks it's now in Pictures/Hawaii 2010.
Open Apeture and look for your image to check if you can use it. If you can, you are done, at least for this image. But if the image shows a badge with an exclamation '!' then Aperture probably thinks the image should still be in /Pictures. If so, select the image and Choose the 'File->Locate Referenced Files' menu item.
You will see a screen like this (you may also need to click 'show reconnect options' if the bottom half of the screen is hidden). From here, select the missing image in the top half. Then in the bottom half, navigate to your /Pictures/Hawaii 2010 folder (where the images now are) and select the corresponding image. The reconnect button should become available, click it to reconnect.
