![]() The hard disk that was in the 320 GB rugged disk enclosure is a 5400 rpm Hitachi HTS543232L9A300 – exactly the same model as was in there before, only with 320 instead of 160 GB. Yay! Everything is working as it should be. Turn around clockwise three times and counterclockwise seven times. In this case, I only reached the fourth plug when I noticed that is wasn’t firmly plugged in. Well, I took the thing apart once more, now doing what all technicians do when machines fail for unknown reasons: unplug and replug every single plug that you can reach. Still no startup, still only the worrying LED blinking. I disassembled the case once more, did not find anything wrong and reassembled it again. Instead it blinked – very rapidly and very faintly! Uh oh. What got me really worried was that the Magsafe power plug that goes into the laptop did not show the regular red or green light dot. It did not even make the famous gong sound anymore. Because of this, the MacBook Pro would not start at all after I exchanged the hard disk and screwed things back. (You need a # 7 torx and a # 00 phillips for the MacBook Pro, though.)Įverything went fine except for the fact that I accidentally unplugged a tiny plug on the logic board when I took off the keyboard. You don’t even need any special tools for exchanging the drive in the rugged disk frame. However, you can just pull the very flexible rubber bumpers and then extract the metal shell. My main worry was if it would be possible to extract the hard disk from the LaCie rugged disk shell or if the nice rubber frame would be glued to the case, thus making it necessary to damage the case. Using the excellent tutorials offered on iFixIt, replacing the drive is about a 15-30 minute procedure. The exchange was not as easy as it was with my trusty old Pismo Powerbook, but it also was much less of a hassle than exchanging the hard disk of my first generation Blueberry iBook.
