Upgrading the system disk on my Macbook

Over the weekend, I upgraded the system disk on my Macbook. It was a 250GB 5400rpm SATA drive originally. It's now a 500GB 5400rpm SATA drive! Hurrah!!!

For the curious and not-so-fainthearted (i'm kidding - it's really quite straightforward), here are the steps :

• Go out and buy a 500GB disk (or whatever size you want to upgrade to, but 500GB is pretty much the max for a 2.5" SATA disk right now). Oh yes, obviously, it has to be 2.5" with a SATA interface. You could get a 320GB one with higher speed (7200rpm), but I was worried about power consumption on my Macbook, and if i get a faster disk, it would probably mean the battery will not last as long.
• If you have another USB (SATA) drive, and if you feel comfortable removing the disk from the case, you can use that. If not, go and buy a USB enclosure for a SATA drive. They're pretty cheap now. In any case, you should put your brand new drive into a USB enclosure.
• Hook your USB case with your new drive to your Macbook
• Download SuperDuper ( http://www.shirt-pocket.com/SuperDuper/ ) and install it
• Run SuperDuper and use it to backup your system drive to the USB drive as a target (SuperDuper will prep it, copy the files, and then make your target drive bootable)
• When backup is completed, if you want to verify that your drive is bootable, shutdown your Mac, and boot it up whilst holding the Option key, and choosing the USB drive. After verification, you should shut down your Mac
• Remove your new drive from the USB enclosure
• Flip your Macbook over, and remove the battery cover. You will see your existing hard drive. 
• Use a screwdriver (obviously) and remove the screw holding down the mounting rail. This should be a single screw, and it's the one that's sitting the highest, round about the same level as the top of the hard drive. Remove the mounting rail.
• Remove the drive, and the SATA connection cable (gently does it now....)
• Remove the mounting screws from the original drive, and put them in the new one. There should be 4 of these, and they are little pieces sticking out the side of the drive. You'd probably need a pair of needlenose pliers for this. Place them in your new drive (duh!)
• Connect the SATA cable to your new drive, slot it into place, and replace the mounting rail. Screw it into place.
• Replace the battery cover
• Boot up your Macbook (cross your fingers first if you are superstitious)

There you go. Not difficult, even though it may look it from the details. Bear in mind, the details are a little more.... detailed.... than I would have normally written it.
