Regardless of the system, a Boot_Install or compact flash install should setup the drive to function for the respective system.
I believe for the 200, the software sets up the drive to a static value for the operating system partition(s) and the remainder for voicemail. On the 3300 it is different so that the dual boot from partition feature is setup, this allows the online-offline upgrade thing to work.
I have seen 3300 systems using Maxtor, Hitachi and Fujitsu drives shipped from the factory.
