Hey,

My friend at work who's wanting to change out his hard drive in his laptop wanted to know what kind of HD you recommend? Also he wanted to migrate things over from his previous HD like we did with mine. What kind of chasis will he need to do the firewire migration assistant?

Here are his specs:
Model Identifier:    MacBookPro1,2
Processor Name:    Intel Core Duo
Processor Speed:    2.16 GHz


Intel ICH7-M AHCI:

He'll either need to borrow someone's macbook that he could throw the old drive into or invest in an enclosure.  

2.5 SATA with firewire for migration at the point of install or he could just use a 2.5 SATA with USB and just use the migration assistant to pull the data over after a generic user has been created.  He'd then go back and delete the temporary user.  

The migration assistant will work via firewire in target disk mode, via firewire hard drive at first boot, via USB as a mounted volume at first boot, or via ethernet after the test user has been created.

Here's a list of enclosures that would work.

If he wants to save some money he can just get one of the sub $10 enclosures without firewire and just use the migration assistant later or pull the data as a mounted volume.

It's really not that hard.  I'm making it out to be more than it is.
