Apologies if this has been covered before.
I'm using a 2010 Mac Mini server running 10.6.8 as a client box. One drive is for the system, and the other for image files. I recently swapped one of the drives to use for the system. Unfortunately there was no way to tell which drive was being replaced, and it turned out to be the image drive. The replacement drive had been cloned using SuperDuper from the original, so used SuperDuper to clone the image files back to the other drive, after erasing it first. So now I'm back to one drive with the system, and the other with images, just as before. I had named the newly created image drive the same as the original.
Now, when accessing that drive in the library, all images have the dreaded question mark. Tried several methods to overcome this with no result. Didn't find anything to address the problem online or in help.
To add insult to injury, I'm shuttling between two residences twice a week and getting ready for two weeks abroad, so dealing with sleep deprivation at the same time.
Hope there's an easy solution.
