Doing a clean MAC OSX install with a RAID Array

I have a RAID array (the one where you have two drives that mirror eachother, dont know what its called) on my Mac Pro and I want to not only reinstall Leopard but would like to securely wipe my data off the drives (one pass is probably fine, i am not THAT paranoid).

Are there any special steps I need to take?

Can the OS be reinstalled on my RAID array by simply booting from the CD and following the same steps as reinstalling onto one drive?

As a non-technical user I don't have much of an idea what I am doing, so any help would be appreciated. If you need any clarification just ask. Thanks.

 

I think you will need to break the array, then do the secure erase on each of the disks then recreate the RAID 1 array. You can do this from the install media before you reinstall.

As a normal practice I re-create the Array every time I do a fresh reinstall.

 

Alright thanks
