I have an older computer, no USB 2.0 and no open card slot to install one... but I do have a Soundblaster Audigy that has a 1394 port on it. I have in the past used this port under Windows 2K for a digital video camera... but have never used an external hard drive nor used it at all since upgrading to Windows XP.
So anyway, I needed a new hard drive and bought one last night... I put my old drive in an external enclosure to copy files over afterwards... but my computer doesn't seem to recognize the firewire connection of the drive. My computer does recognize the port itself within Device Manager (I see the OHCI device as well as a 1394 networking connection).
The enclosure and drive works fine via USB, so I've been going the slow route to get my files transferred... it's a 100GB drive so it will be a while at USB 1 speeds!
I figured I'd post and see if anyone else has any experience (even better if with an Audigy 1394) with external firewire drives and XP.
