Ground is ground. I assume you're talking about a standard 4-pin Molex 5"/3.5" disk power connector. Chances are excellent that both are attached to the same point inside the drive, so they had BETTER be at the same potential. If they are merged together into one wire it needs to be sufficient to handle the sum of the current on the +5 and +12 lines.
