Anyone else experiencing the same problem? Macbook 2.4Ghz with Leopard 10.5.8, 320Gb drive (2 partitions) Doing the standard upgrade install so I shove the SL disc in and run the installer, after an age it eventually reboots. Then after another long wait the installer finally appears but when it asks to choose the drive to install to, my drive doesn't appear. From the utilities menu, I can access disk utility and it only shows the DVD drive. If I access system profiler my hard disk is still there in the SATA section. Seems like I'm going to have format and do a clean install unless anyone has any ideas?
