Okay first you do not need to ask that question in every thread. I seen the top[ic in the mac area and that is where it should be. Honestly i dont know cause i have never used a mac. But i am sure you would need at least a dual female VGA cable.
Well do the lights work at all? Like i said. My honest opinion is to just take it to someone who knows how to distinguish the sounds. At least that way we can figure out what we are working with. Cause if it is the drive dying all the times you turn it on and off might be limiting the option to get data off of it. IF the drive heads totally fails you will need pro services which cost a lot of money to recover your data then.
