My hard drive crashed all of a sudden last week, and I ordered a new 160 GB Seagate to replace it. I was able to save my important files to an external disk befre it went completely. I just switched the old drive in the back bay with the new one, leaving it on cable select. When I start up from the Tiger disk however, the new drive doesn't show up in the selection window of the installer. Am I missing something, or is something wrong? Do I have to format the drive somehow, and if so, how do I do that? Thanks.
