HDD Utility Disc will NOT recognize a non-Sony drive. It will say it can't detect a HDD, so it won't even let you get as far as trying to format it. You can format it to the PS2 file system with several computer programs, but that still won't enable the support, as the SOCOM II disc and the disc with the map on it (along with every official game disc with HDD support) scans for the Sony HDD firmware individually.
