I am writing for a bit of advice. I have a mid-2011 27" Imac that started misbehaving a few weeks ago. The boot-up times are extremely prolonged. I went to the genius bar today. They were able to run diagnostics on it, and the genius suggested they replace the graphics card per the replacement program but also felt that my hard drive is likely bad (but did not run the hard drive test). He quoted me a price of $226 to replace with a 1TB HDD drive. Ridiculous! My AppleCare appears to have expired in september. Any strategies to get apple to do the right thing and replace this under applecare? If they wont replace under applecare, I think its silly to pay that price for that drive and would prefer to upgrade anyway. How difficult is it to replace the drive? Give me some ideas what you have done, HDD + SSD? SSD only? Any chance if its our they will just pop in a new drive for me while they have it apart for the videocard? Uses are mainly home use with light video editing, photo editing and gaming. Thanks for the help!
