I have a Mac with Mac OS X 10.5.8 installed. My 160 GB hard drive is almost full and I want to replace it with a 500 GB hard drive. What is the best way to transfer all data (including the system configuration) to the new drive?

I have some limitations: - I don't have a SATA USB adapter

And some tools: - I have storage on my network, with enough capacity to put all 160 GB content there.

I thought about using Time Machine this way:

  1. Backup my 160 GB hard drive to my Time Machine hard drive
  2. Remove the 160 GB hard drive, put the 500 GB hard drive
  3. Install Mac OS X on the 500 GB hard drive
  4. Restore from Time Machine

I'm almost sure this will work, but I want an easier, quick and intelligent solution. What could it be?

I have done that and it works flawlessly. I don't think it gets any easier than that. Just go for it. – Guillermo Esteves Aug 27 '09 at 15:17

You can use Disk Utility from your install DVD to make a disk image of your internal hard drive to your network drive. Then after having switched from the 160 GB to the 500 GB hard drive, you restore your disk image to the 500 GB hard drive, also using Disk Image from the install DVD.

I can't create a image from my HD, it says my 'Resource is busy' – Daniel Cukier Aug 27 '09 at 13:59
Did you boot from the Install DVD? – mouviciel Aug 27 '09 at 14:01
It worked well with Install DVD! Thanks! – Daniel Cukier Aug 30 '09 at 14:16

Carbon Copy Cloner has worked every time for me in the past. And it's free!

Extract from the site follows: CCC 3 features an interface designed to make the cloning and backup procedure very intuitive. In addition to general backup, CCC can also clone one hard drive to another, copying every single block or file to create an exact replica of your source hard drive. CCC's block-level copy offers the absolute best fidelity in the industry!

This should work if I had a USB SATA case to put my 500GB HD simultaneously with the 160GB. But it's a nice tool. If I can't find another way, maybe the best thing to do is find the USB case and use CCC – Daniel Cukier Aug 27 '09 at 14:40
The best fidelity in the industry is the dd command from the terminal, available on any Unix/Linux distribution. – mouviciel Aug 27 '09 at 15:16
