I wish to use SubRosaSoft Volume Works to partition my iMac 230GB HDD, prior to the installation of an earlier version "Parrallels Desktop for Mac" or if required later version i.e. version 3.0. Can that be done?... if the answer is yes any special consideration should be given to the partitioning.If the answer is no...does the Parallels Desktop 3.0 for Mac allocates is own partitioning, if so.... what HDD memory & RAM is requierd to run XP window professional. Any suggestion or help is appreciated Thank you
