We're still using the UUID to manage this, but here's a solution for you. NOTE: please, this is only for advanced users. Normal users shouldn't be doing this, so -- if you're a regular user, don't, OK?

For the advanced, though:

We have a little program called SDDiskTool that's inside the SuperDuper bundle you can use to do this. It's in SuperDuper!.app/Contents/MacOS/SDDiskTool. You'd use:

SDDiskTool -g /Volumes/some-disk-name

to get the UUID. Then, to set it, you'd use:

SDDiskTool -s the-UUID /Volume/some-other-disk-name

So, pick the one you want to be the original, and set all the other UUIDs to be the same. At that point, we're going see any of them as the same drive...

Hope that helps!
