Wiping internal HDD of Mac mini, and restoring files

[Shamus]

Hello all,
I have a Mac mini 1.66ghz Core Duo, and I today bought a new 250GB HDD to replace the 60GB one inside. I also bought Leopard to install onto it.

I have an external 320GB HDD that has about 200GB filled. I have copied the documents/photos etc from my internal drive to my external drive, so everything I want to keep is on the external.

Now I want to do two things:
1. Format the new internal HDD so that I can install Leopard
2. Wipe the old internal HDD so that I can re-sell it.

Can anyone suggest the best way of doing this?

1. My guess is, just put the Leopard DVD in and select "Erase and Install". It will format it for you along the way.

2. You use Disk Utility to do it. Here is how: Link

Hi thankyou for the reply, I ended up figuring it out. My problem was that I didnt realise you could access Disk Utility without Leopard actually being installed on the drive
