Hello out there! My I am running a Macbook 10.6.4 My EXT. HD is about 9 mos old. It was working fine and then a few months ago it was not able to be read my laptop, no icon no nothing. Unplugged EXT HD and restarted laptop, nothing. Left it alone for a few days and when I plugger it back in it was fine. Now it has gone off again and it has been over a wek and there seems to be no way of bringing it back. ANy ideas.
