Good point Allan, I guess I was going along the lines of an unfamiliar user with such points as he first mentioned that when he started it up the next morning that he received the flashing OS folder which I assume! (not sure!) only indicates that the disk was recognised but had no valid starting system? Because of this he then tried using various tools to diagnose the system only to find that the OS (I am hoping that he misquoted HD with OS and data here) didn't exist as it was deleted. (bit of sherlock holmes guessing here! Joe can you be more specific about the conditions, please?) I am hoping that he didn't do any serious damage to the OF, (thinking happy mac thoughts here) as he could start with an external system and it also ran long enough to find out that the OS didn't exist. Hopefully it is only the description that needs clarification. Joe, excuse the obvious question but when you started up in the backup system and used Disk Utility did you see any disk drives in the left hand side of the window? The right hand side is blank until you manually highlight a disk in the left... AFAIK, you need to boot into the OF to be able to *play* with it (and therefore mess it up)...but I could be wrong. Didn't think of the HD failure...could be... Lets hope and wait for more details...
