I purchased a 20" iMac upon release, had the mid plain replaced five months ago. A week ago the computer wouldn't turn on. No problem, they sent me a new power supply. After installing and turning the computer on, I was treated to a flashing question mark and folder. I attempted to use disk utility and disk warrior but they would not mount. I re installed the OS and noticed no option to archive and all the hard disk space was free. Sure enough, after install everything was gone. Hundreds of hours of work, pictures, music, documents, programs, all of it gone. I called Apple, talked to the tech person then talked to a product specialist and explained I was no longer comfortable using this computer after two repairs and now worse case scenario, a total wipe of everything, and would like a replacement computer. He said no, since it works fine now and it doesn't fall within the criteria for replacement. I attempted to offer paying money and share the cost of a new computer. I was told if I wanted another computer I's have to pay full price. This is my first experience with a Mac and I am a little more than disappointed. I just bought a OWC external hard drive and a copy of data rescue. 80% of everything is gone. I now know I should have had an external but never needed one in the 10 years of owning a PC and certainly didn't think of buying one for the Mac. Lesson learned. Do you think I am being unreasonable asking for a replacement? If not, should I call back and speak to someone else? Any other thoughts?
