Hey All, I need to start this thread first to see if there are any ideas. I'm running vista home premium X64 on and an AMD dual core. Everything s great> Enter the Western Digital My Book Premium II 1.5 Terabyte external drive. I find out it's not really Vista compatible after all. Vista does not enumerate an ieee 1394a device (it has to announce itself). So I try to edit the registry so vista will enumerate it..nothing. I also tried deleting IFCACHE1 so Windows would rebuild it's usb driver to recognize it...nodda... I imagine if it had eSata capability I'd be up and running already. Any help on the horizon?
