Hi Dan,

I have an G4 Tower that plan to re-built and install OS X Server on.
I plan to, among other things, add two new 80GB drives for the
OS both mirrored. It's with the software raid which I know is not
ideal but I can live with it.

I want to install one drive and get it up and running during off peak
hours but still be able to use the current drive and access
the data on it. When I am happy that the new drive and install is
complete I will swap the current 40 GB drive for a second 80GB
and then the plan was to mirror them.

Can I do this or do I need to initialize both drives at the same time?

You can do this. You'll have to use the command line though -- in
particular you'll do 'diskutil enableRAID' followed by 'diskutil
repairMirror':

I don't know if this will be supported on this Mac. The man page makes
a vague reference about it not working on all hardware. I take that to
mean older Macs are out of luck.
