I still cant configure the drive properly in my A1500 to use all the space, even though I have the Buddah card.
Various versions of the HDToolBox actually "lie" about the capacity of the drive when initializing it. That's due to a math bug in the HDToolBox (not using 64bit math).
So it could well be that the drive is all there, even though HDToolBox claims smaller capacity.
