Ok ok, so the title is a little deceiving. I can boot my computer, however, I cannot easily change the boot drive. When I boot the computer holding the option key it starts showing the possible boot volumes but before the mouse changes from a watch to a pointer the computer freezes and you can't move the mouse. I let it sit like this for a few minutes before hard restarting the computer. This has happened several times. Any ideas? The computer is a FW800 Single 1Ghz w/768mb ram and 4 hard drives, 60Gb, 30Gb, 3Gb, and 2Gb. Thanks for your help.
