with one recovery, after 18 months.
Fortunately, I had a Time Machine backup which put everything back as if nothing had happened.
Purchased my brand new 24" iMac August/08. Never had any problems with it until last week. Got the file folder with the question mark after waking up from "Sleep". Phoned Apple Support, went through a couple of requests, and was told it sounded like my HD was shot. Took it to the Apple Store, the Genius hooked up his HD to it, said everything looks good. Disconnected his HD, restarted my iMac, and it started up fine. He said that his HD may have corrected whatever was wrong with it. Took it home, started it up the next day, it ran fine. Put it to sleep for about 8 hours. I have never done a backup, and the Apple Store says they don't do that, and if they had to put in a new HD, everything will be lost. I went out and bought a Maxtor 640 GB External HD so I could do a backup. Then when I awakened it, I got the folder with the question mark again. So, no backup has been done! Back to the Apple store, where a different Genius hooked up his HD, and he said it didn't recognize my HD. Said to leave it for repair, and they'd check the internal cables first, and if all OK, then they'd replace the HD with a new one. (This was Monday, today it's Friday and when I phoned to check on it I was told it's in queue for repair, but no results yet) When I was waiting for the Genius the second time, I was talking with another customer also waiting for his appointment. He had the exact same machine as mine, and the same problem. He said he had done some investigating, and found out that the Hard Drives that Apple put into these iMacs were FAULTY. His serial # prefix was the same as mine, and he bought it from the same store, around the same time. Just wondering if this has been a common complaint with the 500GB HD?
