Thank you for the clarification, Frank.
I am an optimist, and when in doubt, I tend to hope for the best, you seem to suspect the worst, and probably is that by far the wiser way to do it.
Please be our guardian angel at this tricky stage of the operation and chime in again if you spot further trouble.
@ Kevin,
Either way he has to clear this up and decide how he wants to proceed because leaving it in the current state is a recipe for disaster
To make really sure you know exactly where each of your masters are, here is a three stage plan: Back up your System drive and your iPhoto Library before you proceed.
- consolidate all of your masters into your Aperture library
- then relocate all your masters to a dedicated folder on your external drive, back up the folder with your masters
- Create a small working set of current projects: Now make up which of your projects and their masters you want to work with in the near future (working set), then consolidate these few selected masters inside the Aperture Library.
This should give you with a little extra work the setup I recommended to you, and hopefully take care of Frank's concerns.
How to achieve "1.": That will depend on the amount of disk space available on your main drive. If you can afford to consolidate the Aperture Library right in place where it is now, then do just that, otherwise copy you Aperture library to the external drive, then consolidate the masters there.
Open the Aperture library in its new location, select all images in the browser and from the File Menu select "Consolidate Master ...". This will move or copy all your masters into your Aperture Library.
How to achieve "2.": select all images in the browser and from the File Menu select "Relocate master ..." and relocate them to your external disk.
By now you should have exactly the setup you were asking for in your original post.
Now to my suggestions for a setup to be able to work without always having to connect your external disk (3.):
- copy the by now much smaller Aperture library back to your internal disk, if it is on the external disk
- and consolidate the masters of your current working set into the Aperture library
Post back, if there are still questions

Léonie
