Ok, I have a Lacie Rugged 1TB HD. My 24'' iMac (running Snow Leopard) reads it fine. But my new Macbook Air (running Mountain Lion) does not recognize it. The HD does not show up in Disk Utility on the Air either. I have taken all the date from the HD and backed it up on a separate external HD. After that, I erased the Lacie and reformated it to the "Mac OS Extended" and the Macbook Air still will not mount to the Lacie external.


Is there anything I can do to get the Macbook Air to mount to the Lacie HD? Any advice would be greatly appreciated. Thanks in advance.

    Have you used other external drives on the air before? Are you using thunderbolt or USB? If you bought your air from apple you should take it in to a store and have them check the ports. You could run an extended hardware test, although I'm not sure if that would check the ports working ability.

    Yeah, It can recognize my Seagate just fine. The Macbook Air is straight out of the box and new. Can the new Macbook Air computers not recognize certain External HDs?
