My iMac hdd and superdrive died a few months ago. I took out the old drive and installed a SATA 3 OCZ Agility 4 120GB in a drive sled, this installed OS X BUT could not boot. I tried a SATA 3 1 TB WD black drive and it could not be detected at all. I then tried a 500GB SATA 2 Seagate barracuda HDD and it could not boot. Only the barracuda worked in my power mac. I am now suspecting this is an OS X issue, so I will try to install fedora on the OCZ Agility. Because the superdrive cannot eject DVDs I will have to install fedora from a usb drive or have no back cover on the iMac and have the superdrive taped shut. Will fedora work on the SSD? If not, what are some drives that will? How do I boot from a USB holding the yaboot linux boot loader.
