EDIT: I obviously didn't choose my words correctly because everyone would rather pick apart what I said and did rather than acknowledging that... Apple sent me a scratched Snow Leopard disc. These things do happen so make sure you always backup your data and always check the disc before you put it in your computer. Even if its from a company you love and trust. ORIGINAL POST: So Snow Leopard arrived today and without wasting any time I popped the install dvd into my macbook and begun the process. It was all fine and dandy until I got toward the end of the installation. Everything suddenly stopped installing. The load bar just hung. And it kept hanging for an hour or more... Eventually I decided to call Apple. A guy in tech support told me to try shutting down and resuming the installation, so I did. However when I turned my macbook back on I got nothing. No resumed install... Just a blank white screen. Followed five or ten minutes later by a blinking folder icon with a question mark in it. The Apple tech told me "this was bad" and asked me to pop my original leopard install dvd into my macbook so we could repair the permissions. To our surprise when I ran the utility on my Machintosh HD there were no permissions to repair. There was nothing that could be done other than a clean install. The faulty Snow Leopard dvd had trashed my partition and everything in it. Wow... I ejected the Snow Leopard install dvd to examine it. Surprise! It was scratched. Not a small scratch. Big ring-like scratches all over the install dvd. It looked like a vinyl record. My disc drive has never done this to a disc and afterwards I tried it on a few CD's to make sure... They came out fine. So the conclusion we reached was... Apple sent me a scratched disc. NICE! So apparently they're sending me a new Snow Leopard dvd. In five or ten days... But that doesn't ease the pain of me having to restore all my apps and files. I decided to post this for two reasons... 1.) I want to call Apple out on this. It was very lame of them and they haven't offered to compensate me in any way for the trouble that was caused by this. 2.) Advice... Always check a disc before you put it in your drive.
