    My late 2012 iMac has been running great for the past 4+ years, until last week, when it suddenly started running slowly, hiccuping at the simplest of tasks (opening Safari, loading an image in Preview, creating a calendar event, etc.). Then the computer started making a clicking/chirping noise. I verified and repaired the HDD, booted in safe mode, and the problem persisted.

    After poking around the internet for advice, I separated the SSD from the HDD so it's no longer a Fusion drive. I had already backed everything up, so I decided to wipe the HDD with Disk Utility and start with a clean slate. So I started to format the HDD - just a single pass of zeros, not the high end security settings. That was two days ago, and it's only about a quarter of the way through the one pass of zeros. The drive is 3TB, but I imagine it shouldn't be taking this long. Do I have any other options other than just waiting a week for it to (hopefully) finish formatting? Or is this a sign that the HDD is bad and I should just replace it? Any help is much appreciated!

    You mentioned it's the 3TB and was the Fusion drive setup. There is a known issue with the 2012 iMac's with the 3TB and you should be able to get a free replacement. Check out the article below.

    Crap, I didn't know about that. Looks like the replacement program was only valid through Dec. of 2015. Guess I'm SOL :(

    Try it anyway. Sometimes they replace it for free after the mentioned period.

    Take it to a Genius Bar and be ever so nice and polite, and tell them about all your Apple idevices. In other words, crawl!

    I took in several for my work last year and they never said anything about it. We are talking about 35-40 machines spread out throughout the year.

    Definitely try anyway. Escalate the issue to someone that can help you if they can't in the store. You may find them willing to help you out in one way or another. Nothing to lose anyway.

    Realistically they may not be able and/or willing to help you because HDD's do eventually fail regardless of defects or not.

    The user above me may have had much more pull then you do because of the volume of machines he works with. Plus it makes it hard for Apple to say will units A thru D were because of a defect but units E thru Z weren't. Basically they already admitted fault and its hard to retract that.

    Still its worth a shot.

    Apple just picked up my iMac this morning for the HD issue. It is the 3rd time I've had it repaired, for a total of four issues since I purchased it in early 2013.
