I'm afraid there are no drivers running under Windows Vista for this unit.
If you have the W XP install disc , you could install a virtual version of W XP on your HDD ( http://downloads.vmware.com/d/info/desktop_downloads/vmware_player/3_0 )
You could also partition your HDD ( http://www.partitionwizard.com/free-partition-manager.html ) and install W XP on the new one .
