Now I see. In your previous output of "fwcontrol -p" I mistakenly inferred that a "Negotiated_speed" of "3" meant something was connected. Instead, that appears to be the default. The clue should have been that the Negotiated_speed of "0" was where the Maxtor was connected. "0" in this case, shows that the firewire stack just plain failed alltogether to negotiate correctly(since your Maxtor is 400/800). So, now I need to go and add some debugging and figure out what is going on when you connect the HD. Are you comfortable with patches to kernel source and recompilation? Seanhome | help
