Hi, I have an appointment at the Apple store on Friday (which I've waited stupidly long for!) regarding my MBP - just looking for some advice before I go. Basically I opened up the MBP and it came on from it's sleep, but the cursor wouldn't move. It wouldn't respond to any commands, so I held down power to force shut down. When I powered it back up, I got the dreaded grey screen + folder with "?" symbol inside it. I phoned Apple Care, we tried hard disk recovery but that didn't work. We then tried internet recovery, and that didn't work either. It basically can't recognise the hard drive. I've been told it could turn out to be as simple as the cable connecting the start-up disk being faulty/knocked out of place, or as unfortunate as the hard drive packing in (which will also mean I've lost an awful lot of stuff). In the worst case scenario that the hard drive is completely knackered - how much am I looking at for repair? And is it likely that I'll be able to retrieve any data from the hard drive? If so, any idea of cost/best place to go for this? (I've heard that Apple store don't offer this service).
