Upgrade Hard Drive in a MacBook Pro
Last week I was running out of space again in my MacBook Pro. I've gone through this again and again (always running out of space - deleting files or moving them to a separate storage device to get a little more space). I finally decided it was time to upgrade.
Speed has also been an issue. For the last 3 laptops (since 2004) I have always purchased them with 7200 RPM drives. When I purchased this MBP last summer the largest 7200RPM drive they offered was a 160GB drive (with 8MB cache). It's actually a pretty decent Seagate drive.
At the time of this blog post, the largest 7200RPM drive for laptops is 320GB with 16MB cache (or 500GB for 5400RPM). Over the past 5 years I've had a lot of bad luck with 3.5" Western Digital drives (almost all of them have died - poor ventilation in my NAS I guess). But after doing some research I decided to get one of the Western Digital 320GB hard drives (the WD Scorpio Black 320GB drive without free-fall sensor (WD3200BEKT). I made sure not to get the one with the free-fall sensor (built-in shock protection) because there have been multiple reports of people having kernel panics when physically moving the laptop (a conflict between the HD's shock detection and the MBP's head parking technology). Although I could not find any official data (from WD or Apple) to back up this claim, it was enough to make me be more cautious and avoid the possible issue.
The whole process took about 3.5 hours (3 hours to clone the data from my 160GB drive to the 320GB drive, and a half hour to swap the drives).
When I was a PC repair tech and network engineer in the 90's I repaired quite a few laptops. I have to say, they were much more complicated back then than the ones I've taken apart over the past few years (IMO). Apple's was even easier. But I wasn't without help. I found this great walkthrough which saved me a lot of time. If you're considering doing this, let me give you a helpful tip I learned from a tech who trained me back in 1994. Before taking out screws from a laptop, grab an empty egg carton (qty of 12). As you move through each set of screws, use a new compartment in the egg carton (makes things so much easier :) ). Also, make sure you have the correct tools (I was lucky enough to already have precision screw drivers on my workbench - saved me an extra trip to the hardware store).
I also saved a lot of time by purchasing an external hard drive enclosure (I purchased that particular one for other reasons - I have a couple other SATA 2.5 and 3.5 drives I've been meaning to retrieve data from and this will make things much easier. Also, I found that device to be much cheaper on Best Buy, but I've had so much bad experience with Best Buy over the years and great experience with NewEgg that I'll keep going with the better service. I do, however, wish the device had Firewire 800 :) ). I was originally planning to use one of my existing USB external HDDs to clone the data (make an image), and then use the same drive to restore the image back to the new HDD, but I skipped the middle-man by using the enclosure and just moved the data over in one step.
So here's a breakdown of how I replaced the drive (3.5 hours):
- Researched some hard drives and chose the Western Digital WD3200BEKT drive for it's overall balance of speed and power consumption (speed being the more important factor for me). Suggest: Newegg.com or Amazon.com.
- Shutdown all programs on my Mac and disconnected from the web (don't want some auto-update running by mistake)
- Mounted the new drive to the Mac (now in the enclosure unit) and formated it (use "Applications >> Utilities >> Disk Utility". Select the new drive (which shouldn't be formatted yet if new) and choose "Erase" with the default setting of "Mac OS Extended (Journaled)).
- Used Carbon Copy Cloner to clone the data and make the new drive bootable (took 3 hours)
- Shut down Mac and installed new HDD
- Booted up Mac with new HDD (it was a slow bootup the first time - see next step)
- This next part I couldn't find documented anyhere on the web. I just happened to catch some guy talking about it in a forum after having slow bootups from my recent restore.
- Go into "System Preferences >> Startup Disk", select the new drive, and restart (your bootup will be much faster now).
I'm not sure if this upgrade would void my warranty with Apple (I have Apple Care), but if I have to send my MBP in for repair again in the future, I figure I'll just have to swap out my new HDD with the original before sending the laptop out. It's possible I could have paid Apple a large sum of money to upgrade the drive (note: They don't sell anything larger than 200GB 7200RPM) just to protect my warranty, but after having a bad first experience with an Apple Genius, I'd prefer to just do it the right way myself.
