Hi guys, bought a refurbed whitebook towards the end of last year. I was happy with it until february of this year when it stopped booting to mac osx, to which the apple store confirmed was a failure of the hard drive, which they replaced. Not more than a week later, same symptoms, apple store replaced hard drive again. Now to top it off a week after having it back again, I am having the same problems and it again refuses to boot into osx. This time I had the sense to install bootcamp and windows vista, which funnily enough boots up fine, and using mac drive I can read the mac hfs partition, and have also checked the smart status of the drive which reports its status as good. I'm getting a little annoyed now as I didn't shell out good money to use windows on my macbook which is surely understandable, and its costing me money going back and forth to bristol - my local apple store. Would it be reasonable of me to ask for an entire replacement computer as surely there is something more wrong than a faulty hard drive?
