Not that I could tell. I was watching my root console the entire time.

I tried a `fwcontrol -r` and nothing happened on the root console. I'm not
sure if I tried `fwcontrol -t` or not. I'll try that tommorrow and see if
I get any different output.

Not with the powerbook attached. I went to a local computer store and tried
a different 4 pin to 6 pin cable with just the hub, hdd, and my 4 pin laptop.

I don't think I'll get a chance to test with another cable either. I guess
I need some way to verify that:

a.) The port on my laptop isn't bad.
b.) The 6pin to 4 pin adapter I'm using isn't bad.
c.) My cable lengths aren't too long for some reason.

I'll see what I can think of...

Is there a chance that my hdd is not SBP-2?

Could you describe, in detail, the devices you use, including cabling, hubs,
and power sources?

Yeah. But I'm looking for a specific card so I don't get burnt. Does anyone
here have one they like?
