I thought I was lucky getting an Apple refurbished 2.6GHz Quad core I7 with a 1TB fusion drive. Well it arrived today, and when I started it up, all there was, was a grey screen with a no entry sign on it. No operating system? OK not impressed, but I can install from the internet, so I pressed cxmd+R and off it went to get it, but then when it came to install it said no hard drive found? So I started up disk utility and saw only one 128GB drive, unformatted, But wait it was supposed to have a 1TB fusion drive, where is it? I've tried re-setting the pram, installing a fresh copy of Mavericks, but no show. So I'm left a bit miffed and either I'm doing something wrong or the drive is dead? Any ideas?
