Carefully inspect the hard drive cable for tears or other defects. Make sure it is properly and securely installed. If all these are good remove the drive and format it outside the computer, reinstall and try again to see if it is recognized. If it is install your operating system. If it does not work get back to us and we will try something else. You say firewire mode works well–does that mean you can see the drive in firewire mode?
Try installing a OS Get a copy of OSX snow lepoard while you can, hold option, boot from the OSX DVD, but before you do this, you can upgrade if you have data you need and you can keep it If you have data, select “options” and select “upgrade” if it isn’t already If not, utilities, disk utility, Macintosh HD or whatever it’s name is, erase tab, erase, but you can zero out in “Security options” Select the drive either way and select “customize” and uncheck everything, this bogs the computer down and will maximize the free space you get If no luck or it fails at some point, the drive silently expired and may be time to get a SSD if you can afford it In fact, the drive may already be bad so this is a excellent way to save what you can while you can update This harddrive may have already died anyway or silentley dying so I would go and buy a new drive and try this If it yields better results, this drive died
