    I don't know that I can help outside of what I have already said in this thread.. perhaps someone else will come along with some additional advice.

    I guess I have one thing to say, if it is a western digital drive, check on their site to see if there is a Mac update for it. Suppose its worth checking the manufacturers site for any updates even if it isn't a WD.

    Firstly thank you very much SNGX1275 for all your help.

    OK! I am having the same issue as most people here.

    It shows up in Disk Utility and now I am attempting to repair it now.

    It says there is:
    Invalid key length??
    Invalid sibling link...??

    And then that the disk cannot be repaired... (check out the screen shot).

    I have used this WD drive with my Macbook previously, why now is it not working and am possibly going to loose a lot of my data because I have to reformat the disk??
