I don't believe all instances of this type of failure have the same cause, those reports where the box recovers is indicative to me of one or more capacitors failing, its known that failing capacitors have the habit of changing their characteristics such that they can for a period return to a state where they work again within the cct, however such capacitors usually show physical signs of failure.If it were a bug in the firmware setting a flag, how do you explain the fact that there are lots of reports of boxes regaining accessing to the hard drive if left powered off for long periods of time? I think it is much more likely that it is a component that is going out of tolerance (NB not failed) and this accords with what Humax have said is the cause of the problem.
I don't think you can prove anything by that. Anything could influence the apparent behaviour of the drive at startup, you would need to hook an analyser up to the SATA and observe the signal activity to be certain.Simply comparing the drive behaviour when powering up with the SATA connected and not connected.
That's a fallacy. If the user was happy with the performance of the unit for the period of the warranty, it couldn't be unfit for purpose.I would also point out Humax would be very unwise to point in any way to the cause being a software bug as such would mean the box was not suitable for its intended purpose and under the sales of goods products could be returned long after the waranty expired.
I disagree, consumer lawyers have stated that the sales of goods act provides protection long after the statutory warranty has expired and however well a machine worked initially, if it fails not long after the warranty expires most will be unhappy.That's a fallacy. If the user was happy with the performance of the unit for the period of the warranty, it couldn't be unfit for purpose.
My point was you stated previously 'a component that is going out of tolerance (NB not failed)' was the cause, no engineer would say that as that is wrong, the component has failed in such instance.These reports were from Engineers at the parent company in S Korea, not customer support at all.
