"Greg"?

You're right, of course, that the Tiger discs that came with the mini aren't licensed for use with your PB. But you can go buy a copy later (really do it, of course), and use it now.

You can erase-and-zero with the install CD/DVD OR by booting from the LaCie first. I'm just concerned, if the LaCie isn't named the same as the internal, that aliases will resolve to files on the internal drive and make it hard to erase.
