I meant the full version number:
With permissions I meant the following:
You need to have read & write permissions to the files to be able to reconnect the files. To check the permissions, select an original image filein the Finder and press the key combination ⌘I to launch the "Info" panel. In the Info panel disclose the "Sharing&Permissions" brick.
Check if you have Read&Write access to all your image files, also to the folders containing them. If there is a permissions problem, change the permissions to "Read&Write". It would help to set the "Ignore Ownership on this Volume" flag. You'll find this flag in the "Info" panel for your external drive.
But the safest way really to solve this would be to let Aperture relocate the files to your new drive and not to move them manually. Connect the original drives with your original master image files and move the masters by using Aperture's command "Relocate original file". Then their would be no need to reconnect.
Select all files that need reconnecting
Go to File > Locate Referenced Files
When the window opens, select one image on the top pane and find the image on the bottom pane
PRESS DOWN THE ALT KEY (force reconnect)
RECONNECT BUTTONS SHOULD COME UP-----
In your case, once you have located at least one file, you can then use the « Reconnect All » button and Aperture will reconnect all matching files in the directory.
