    Hi,

    I bought a new Mini earlier in the week (i7 2.3 version, with stock 1TB disk and 4GB memory), found it was making weird noises from the hard disk so took it back today and got a replacement only to discover this one has the same issues.

    But that's another story. The issue here is that what i found when checking the SMART status of the drive has taken me aback somewhat. The stats on the one that i returned showed that the HDD had been on for about 23 hours and had a Load Cycle Count around 640. The replacement i got says the drive had been on for a total of 46 hours and had been powered on 453 times, with a Load Cycle Count of 1340 something. I didn't note the Power Cycle count of the first unit unfortunately.

    These stats seem awfully odd for an ostensibly brand new machine. 453 Power Cycles is incredibly high, and 46 hours seems like a lot of use fresh out of the box. That's something like 9 start-ups per hour.


    Does anyone have an idea what this might indicate?

    Should i take it back again?




    Thanks.

    while interesting
    I don't think it is worth returning.

    Why not turn it on and off 10 times and check the cycle count.

    You might think it's pedantic of me to want to return it for such a minor issue, but i'm spending money to buy a product that i expect to last upwards of three years, and with such an awkward start to its life cycle i can't help but feel uncertain for the future and especially the reliability of such an item.

    It's just baffling to me how a hard disk can be spun up 453 times before ever reaching the end consumer. With such doubts i believe it's worth taking a chance on another unit just to assuage my anxiety.

    The cycle count goes up by one every time the computer is turned off and on again or wakes out of sleep mode. How can it be possible for this to have happened more than four hundred times in 46 hours of its lifespan? And that's even before reaching a retail point. Something just seems fishy here...

    I agree with you and would definately take it back for another.

    It is used before. Probably returned for some reason. Apple doesn't throw them away, they sell them again...

    Which brand and size is your HDD?

    Hitachi Travelstar 1TB. I took it back today; no good. Pity, because the machine itself was very capable.

    Hard disks are subjected to "long-term testing" in the factory. Slide 40 of this tour of Western Digital shows one of the testing machines:

    The idea that you happened to get two instances of a brand-new model of computer, whose assembly takes place in China and production of which only began a couple of months ago, that had somehow been subjected to hard disk replacements with used hard disks that were previously owned by two separate owners who had bizarre habits of turning their computers on and off ten times a day is ridiculous.

    The disks just underwent normal factory QA. Your buyer's remorse is approaching seriously neurotic levels, I think.

    After he fixed the problem:

    Roughly said, on a standard/non-fixed Mac Mini, 1.5 year later, the limit of 600,000 load cycle has already been exceeded and is more likely to fail. Especially after 3 years...

    Apple is doing something what shouldn't be done. Link about it below:

    It seems you mis-understand the actual issue i had with the computer.

    Anyway, my pre-neurotic remorse is now becalmed thanks to the ersatz benevolence of Apple's 14 day grace period for returns.

    I'm not begging for them to bestow me with one of their products, it's my money that enables the transaction. We're playing the consumer game.

    If you consider it neurotic to have high expectations from expensive goods, then so be it, here stands a Freudian object. But i'd rather be pleased with what i buy than buy something in order to be pleased.
