My HD crashed. Can't recover anything. Drive doesn't even show up when I insert Tiger DVD and try Disk Repair. So I took it to the Apple Store and they quoted me at $340 to put a new 80 GB 5400 rpm drive in (don't have Applecare or warranty anymore). The guy told me I could probably get it cheaper elsewhere. He mentioned a site called pbfixit.com. So what do you guys suggest I do? I'd rather not open the PB myself, but I think I want to go with some else rather than Apple to replace it so I can get it cheaper. What are my options? thanks.
