Creating a hidden partition that doesn't mount automatically

I have a drive full of diagnostic images (ASD), and I also use it for storage, installers, etc. When I plug it in to a booted system, it has to mount every single volume (about 25) which can take some time. I would like to keep all the ASD partitions from mounting when plugged in/at boot. I know I can edit fstab on individual machines, but this needs to be a property of the drive, not the computer. It isn't really important to me that the partitions be hidden (not shown in disk utility), but I do need to keep them from mounting.

The OS X recovery partition works in exactly this way, but I don't know how it is implemented. Can someone point me in the right direction?
