Recently I purchased a WD external hard drive with firewire connection for my PC laptop. The drive works perfectly if connected using the USB cable, but when I try to connect using the 1394 firewire port, I get nothing. No power, no connection. I had to purchase a 1394 to Firewire 600 adaptor to connect to the drive but they don't want to talk to one another. Here's what I'm operating on. 500 Gig WD Passport External Hard drive Sony Laptop with XP Firewire 800 to Firewire 600 Cable Firewire 600 to 1394 adaptor Help!
