Symptom
The Mac OS X installer does not display the hard disk icon of a hard drive that is actually connected to the computer.
Note: If your hard disk appears in the installer but looks dimmed, stop here and go to technical document 106235: "Mac OS X 10.0: Disk Appears Dimmed (or "Grayed Out") in the Installer"
Solution
This can happen if you have a single ATA hard drive connected to the computer and it is set up as a slave device (ID =1) instead of a master device (ID=0). If you have both a master and a slave drive connected, all volumes for both drives will appear.
To tell how your ATA drives are set up, follow these steps:
The ID appears to the right of the ATA bus, but to the left of the drive information. To restart your computer from Mac OS X, Choose Control Panels from the Apple menu and Startup Disk from the submenu. Select your Mac OS X disk and restart the computer.

Apple does not ship computers in this configuration. To resolve this issue, set up your drive as a master device. The exact steps to do this vary from drive to drive. Most drive manufacturers post the steps to do this on their Web sites.
Tip: Try putting the model number of your hard drive in a Sherlock Web search.
You should not modify the settings of your hard drive if you are not confident in your ability to do so. Damage caused by incorrect modifications may not be covered under the Apple or third-party product warranty.
