Hi. I'm trying to revive a sluggish iBook G4 (12" 1.2GHz 1.25GB ram) However, although the HD boots fine into 10.5.8, when I insert my 10.3.7 install discs and attempt a clean install, the HD does not appear in the destination section. I've searched around, but cannot seem to find someone with the same problem. The partition map scheme is Apple Partition Map. S.M.A.R.T status is verified. Write status: read/write Does anyone have any suggestions? Many thanks.
