Incredibly my rarely used 2011 iMac Hard Drive is toast. I saw they have a replacement program but even though it is way too soon for a hard drive OF QUALITY to be going out so soon as mine - mine is not included in the replacement program. Which I have a problem with - how odd it is that they had enough trouble with these computers/hard drives to do a replacement program but mine which did the same thing, expired way too soon isn't covered. I've not had use of the computer for 4 months while I tried to fix the problem so it lasted a little over a year. Anyway I need to know what to do to try to replace it myself as i haven't the funds to take it to Apple for repair. Plus, Apple Computers and me are history I will never buy another after spending over $1200 for a computer that's nothing more than a very large paperweight right now. How do I know what size and all that? I may not be able to afford even that so more than likely this is going to be a very nice looking worthless computer going to the landfill.
