When installing 1.0, my largest partition appeared greyed out so I couldn't install onto it or erase it to fix a problem if there is one. My other two partitions are ok. I also erased the disk to HFS+ with Erase Disk.. but no joy.
I can only install the Developer Tools to the other two small partitions aswell, which is a bit of a pain considering they're 600-odd mb.
Why does the Installer app not like that partition?
