I guess I assumed NAS Navigator would be the right software because all the TeraStations use it, but I suppose that makes sense as this DriveStation doesn't have network access. It also looks like all the software for the desktop DriveStations are device specific. So I will have to use the original utilities.
It seems Buffalo has moved away from producing rack mounted DriveStations in favor of marketing them as desktop enclosures. Thankfully my use-case has no need for network access or USB 3.0, so this device is perfect for me.
I bought it for very cheap with the understanding that it might not work. However I love old hardware like this, and I'm pretty experienced with getting these kinds of systems up and running.
Hopefully I won't need any more help, but perhaps I'll post an update if I get it working; just for the sake of documentation. There is virtually none for this device outside of manual.
