    Hi Guys,

    My External HDD worked perfectly with Lion.

    My macbook pro just arrived with Mountain Lion installed. Now when I plug it in via USB the light stays blue on the HDD and isn’t recognised on the mac.

    I plug it into my girlfriends mac with Lion and it flashes white and is recognised so it’s a problem with mountain lion.

    Any ideas?

    Does it show up in Finder after you pressed CMD+SHIFT+C (File > Go > Computer)?

    Does it show up in Disk Utility?
