Hi guys, Long story short, I received my Samsung F1 HD753 HD this morning, and I installed it into bay Two. When I fire up OSX I am prompted with an error message, I believe OSX states that the disk is unreadable , I go into disk utility and the Samsung Hard Drive is clearly listed underneath my BTO Apple drive. Every option within the first Aid Window is greyed out, I cannot verify the disk, or repair the disk, in fact, I don't know if this would even help me at all? I am really confused as to where to do from here, the company I bought the disk from will not return my phonecalls, nor will they answer any questions I pose to them (They're a large Ebay company). Am I doing something wrong here, or is the disk buggered? Any help would be greatly appreciated Thanks BTW It is a new Harpertown MP.
