Faster, bigger, better.

Last week, I finally took the financial and technical plunge and exchanged my MacBook Pro’s internal 160 GB drive with a new 320 GB drive taken from a LaCie rugged hard disk case. 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. Using the excellent tutorials offered on iFixIt, replacing the drive is about a 15-30 minute procedure.
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. However, you can just pull the very flexible rubber bumpers and then extract the metal shell. You don’t even need any special tools for exchanging the drive in the rugged disk frame. (You need a # 7 torx and a # 00 phillips for the MacBook Pro, though.)
Everything went fine except for the fact that I accidentally unplugged a tiny plug on the logic board when I took off the keyboard. Because of this, the MacBook Pro would not start at all after I exchanged the hard disk and screwed things back. It did not even make the famous gong sound anymore. 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. Instead it blinked – very rapidly and very faintly! Uh oh. That did not look good at all. I disassembled the case once more, did not find anything wrong and reassembled it again. Still no startup, still only the worrying LED blinking. 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. In this case, I only reached the fourth plug when I noticed that is wasn’t firmly plugged in. Pushing it back into its socket. Screwing screws back into their sockets. Sacrifice a chicken. Turn around clockwise three times and counterclockwise seven times. Push the power button. Yay! Everything is working as it should be. Yours truly truly happy.
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. Since that means that more (i.e. the double amount) data is put on the same surface, the disk is quite a bit faster than the old one. This is especially noticeable during startups. Very nice!

Putting the data from the old drive on to the new drive was a bit more complicated than I thought, because I used the LaCie tool to format the new disk. The LaCie drive tool formats the disk with the old Apple Partition Table instead of the new GUID Partition Table. Since intel Macs can only boot from GUID partitioned drives, I had to reformat the disk and check the appropriate option in Apple’s Disk Utility before I could use the new drive to boot my MacBook Pro. After choosing the correct partitioning technique, I first wanted to use Carbon Copy Cloner to clone the contents of my old drive to the new one. But the clone was not bootable because of some strange permission issues. Again, going back to the tools provided by Apple made things work: I used Apple’s Disk Utility once more and told it to restore the contents of my old internal drive to the new external drive. This went perfectly well. (I bought one of the triple interface rugged disk models and used the faster FireWire 800 to transfer the data. USB is well-known to suck with regards to data transfer rates…)

I also used this opportunity to expand my Boot Camp partition for Windows XP to double the former size. Thanks to the excellent tool Winclone this was quite easy. I first booted up Window XP and converted the disk from FAT32 to NTFS using the standard windows command. Then I booted back into Mac OS X and cloned the Boot Camp partition to a disk image using Winclone. Then I put in the new disk and used Apple’s Boot Camp Assistant to make a Windows partition twice the size of the old one. In the next step, I used Winclone to clone the contents of the disk image onto the new, larger Boot Camp partition. Finally I used the Expand Windows (NTFS) Filesystem… command offered by Winclone to expand the partition to use the new, bigger size it offers. This worked perfectly well and this gives me enough room on my windows partition to install the new expansion pack for LOTRO when it arrives this week. Ha!

Feeling much safer.

Whew. A bad feeling has been nagging me for the last months. As the amount of video data that I have collected for my Ph.D. thesis began to fill up the external 200 GB hard disk I became more and more aware of the fact that hard disks sometimes fail for no reason at all. Or they get dropped. Or they get accidentally erased. Or the buildings where they are stored burn down. All of these are good reasons to make backups. But how does one backup such an amount of data? One choice would have been to buy another hard disk. For that I didn’t have the money. Therefore I decided to do what I should have done in the first place: always keep a backup on DV tape. That is a pretty inexpensive solution (about € 3 per 60 min tape – one GB of DV equals slightly less than five minutes; enjoy the calculation), and it is adequate to the data. May my sleep be easy and relaxed!
