here’s another way of installing a new HD in a Mac :

in this example a new HD was placed in a MacBook Pro (end 2008) running OSX 10.7 Lion

1- prepare

– put OSX Lion installer on a 4GB USB stick ; for instructions, look here :

make sure you have a new DVD-writable or a completely empty 4GB USB-stick, download Lion Disk Maker and follow the instructions that come with it :

– printout the instructions on how to replace a HD on a MBP 2008/2009 from iFixit

http://www.ifixit.com/Guide/MacBook-Pro-15-Inch-Unibody-Late-2008-and-Early-2009-Hard-Drive-Replacement/841/1

– make a TimeMachine backup

2- replace the HD

– shut down and completely unplug
– use the directions from iFixit to get your current HD out, and the new Momentus XT in

3- install a fresh versions of MacOSX and add your data from TimeMachine

– plug in the USB stick
– startup pressing the ALT key and choose the “EFI Boot” (USB installer) to boot from
– then install the basic OSX EFI
– continue and open Disk Utility
– select the new harddisk and Erase to a “Mac OS Extended (Journaled)” format (to get a one-partition OSX HFS+ formatted drive)
– install a new version of OSX Lion
– during this installation, you are asked to migrate from a TimeMachine ; do that (and make sure you’re connected to your TimeMachine backup-disk through a cable – Ethernet/UTP, USB or FireWire)
– when the install is done, restart normally (booting from your new internal harddisk)
– then update your mailbox (this will be asked and done automatically)
– then goto Software Update (under the Apple logo in the upper left corner) and install all available updates
– restart and boot from the USB stick (“OSX EFI”)
– open Disk Utility and Repair Disk Permissions on your new internal harddrive
– restart normally (booting from the internal drive)
– again, run Software Update to install all available updates (in my specific case, there was a ‘rather important’ EFI update a this point)
– repeat Software Update once more to make sure there are no extra updates
– shut down
– restart normally ; done !
