my external HD Lacie D2 Quadra will not mount anymore

Hi,

Since a few weeks my two year old Lacie external HD (D2 Quadra) won't mount anymore through FW 400 or 800 on my MacPro both in front and rear connection (Usb is working fine though). I also found out that the same external HD still does mount with FW on my Macbook laptop although both machines are using the same OSX.6.8. Also on MacPro in the system profiler I can't see my FW external device. Restarting and refreshinging PRam didn't bring any solution yet. I've also updated the firmware of the HD to the latest version.

Does anyone recognize this problem?

damaged cable? I'm guessing you tried the same cable in all sockets.

I tried both the FW 400 and 800 ports with different cables. I know for sure that the FW400 calbles are ok but did not function on the MacPro. So it didn't solve my problem but thanks anyway.

Well I now believe that my whole FW conection is corrupt. I tried different cables and connection through different FW ports (also some in my monitor) and no device corresponds or mounts. In the system profiler I get the message that FW devices can't be displayed. I have other devices that also connects with FW but none of these mount either on my MacPro. I tried several things now such as unplugging all the cables and then slowly building it up and begin to suspect that my FW is done on this machine. It's a pity that you can't test the functioning somehow other than it's not working.

Here is the boilerplate article on the subject, with a few (very few) side links to troubleshooting:
