    Hi guys,

    I got an iMac 24'' - 2.8Extreme from November 2007 still under AppleCare until this November.
    For the last couple of months or so, I have been experiencing some issues which I relate to a future (anytime now) hard drive failure of the internal iMac Drive.

    The hard-drive has started to make a lot of noise when, for example, I try to extract any files (using unrarX) or when I copy data from a external drive to the internal one. In these situations, the iMac will freeze for about 10/20 seconds while the HD makes a lot of noise and then it will carry on as normal.

    The other day, when I switched it on, I got a logo like this one:

    I managed to get the SL to boot up after the third reboot.
    Since then, the iMac hasn't given me that failure logo anymore, but the HD is still making funny things when I extract files or copy data on to it.

    I have used Techtool Deluxe, Drive Genius 2 and the Apple Hardware Test and none of them show any hardware problems (is it not a HD issue?)

    Also I thought it may have been a problem with the OS and I have reinstalled the SL and it's the same.

    I got an Apple Store about 45mins from home, so I could take it there, but if the hw tools show no failure, then they won't replace the HD.

    Do you, guys, think it's a HD problem? Or is it something else?
    I would like to get it fixed before the AppleCare runs out in November.


    (btw, I got the TimeMachine backups all up-to-date, so losing the HD is not an issue)

    I have a 24"/2.8 Extreme that has "burned" through two 1TB Hitachi HDDs so far.

    Extreme overheating (>73C HDD temperature, even though the HDD is rated only up to 60C) leading to HDD shutdown, thereby freezing all the HDD-pending processes on the iMac.

    Even though the HDD is no longer in production, and is known to run smoking hot, AppleCare would only replace it with an identical model. 6 months later, it needed replacing again. I finally had a cooler HDD installed (I paid for the drive, AppleCare paid for the labor).

    What size of HDD does your iMac have??

    Try running Disk Utility and its repair disk permissions and verify disk. That should either fix it or tell you that it's broken
