    Recently i replaced my MBP 2009 with the MBP 2011 and now my wd external hd doesnt work properly with firewire800 port.


    100gb to copy on external hd , hangs or freeze finder after 600mb-5gb. So i must unplug the extern hd to get finder working again.

    Some say that replacing logic board with the new one solve the problem. A lot of people got the same issue on apple forum.

    Do u have some advice what to do ? MBP still got extended guarantee till 2016.

    In the core of a black hole.
    I would recommend you to startup from an external clean OS X version and boot from it, if this clean OS has the same issues you might indeed have HW problems.

    But, I also read/heard that some (earlier) WD products have problems so this could also be the problem.

    Hmmm i read the same about old wd got problem, but then he said also that wd sends him a new drive which didnt solve the problem.

    So it might be the hardware issue (not enough power on fw800 port).

    Its not that big problem to send my mbp to service but than i will be one week maybe more without a computer.

    Update: HDD is working on my friend identical MBP without any issue. So it must be logic board i believe.
