I am having trouble installing the system on my G5. I recently wiped the drive in my MaPro running 10.6, and now both the system restore disk and an OSX 10.4 installer are refusing to let me install, reporting simply that the system cannot be installed in the drive. SMART status is fine, and the disk utility reports no problems. Any ideas? The machine is a G5, 1.8 GHz, and the hard drive is the OEM drive.
