One possible fix for a non-visible external hard drive
Authored by: thehyperone on Jan 20, '07 06:26:01AM

I don't use any FireWire devices, so I can't confirm resetting the NV-RAM is a solution here, but the procedure listed needs some clarification.

cmd-opt-o-f will get you to Open Firmware. reset-all only accepts the change you've made and restarts. (kind of like a save-and-quit option) To reset the NV-RAM, type reset-nvram (with the hyphen) and press return. OF should respond with 'ok' and another command prompt. Then type reset-all and it'll save and restart. If you want to reset all your PRAM (not part of this hint) do reset-nvram <ok> set-defaults <ok> then reset-all.

I tried this tip on an Intel MacPro and wasn't able to get it to work.

I held down on the option and command keys while also holind down on the "O" and "F" keys to no avail.

THe tip did work on a G4 but still didn't ressurect my LaCie drives.

MacIntels don't contain Open Firmware, so Command-Option-O-F does nothing on these Macs.
