Slope of the Bath Tub

My new DSLR has recently developed some strange fault, in the way of it not writing to memory card, or worse intermittently not writing the precious images to the card.

Now it would be easy to blame the manufacture for making crap cameras or even the card manufacturer for shoddy quality control, but today this is quite the norm its what engineers term the ‘slope of the bath tub’ and there seems to be a lot of hobby photographers in the forums very upset about this regardless of make, so much so, that threats of abandoning the manufacture at considerable cost to themselves and fall out with other loyal brand followers is the norm so I thought I would just chip in this little bit of philosophy regarding the slope of a bath tub.

At first the product works and all is ok, you think great, I have a reliable camera and I can go off on that travel assignment (or holiday) next week…wrong the philosophy of the bath tub slope states that breakdowns happen within the first 8 weeks, logical if you think about it some problems just take time to show up

After that you are running along the bottom of the bath tub and all is well until ultimately wear and tear starts to hamper the product and when this occurs in electronics, or worse mechanical and electronics combined you can hit the tap end of the bath tub a steep incline of problems and cost as you have reached the end of life expectancy.

Mine was a classic case in point, worked fine for the first month and now it skips image writing and gives me error messages, so now I am chimpping after every picture made to see if it has written to the card.

Now it could be the memory card you say… but to do this on several cards of different make? When I have had no problems with them before, suggests otherwise and that this may be a camera problem well see…but I think at this stage its wrong to blame the camera manufacture

    I’ve heard of this sort of thing before… mainly in the context of computers and stereo equipment. Component failures, if they’re going to happen, seem to occur in the first couple of months or so of the kit’s lifespan. If they survive that then normally all you’re looking at is normal wear and tear in the mechanical parts.

    For some unfathomable reason it hadn’t occurred to me that the same phenomenon could afflict digital cameras, but of course it makes perfect sense.
    And I find your particular travails worrying insofar as our cameras come from the same stable, if not the same horsebox so to speak.

    However, I think you’re right not to blame the manufacturer at this stage, especially one of such good reputation; the likelihood is they’ve simply assembled components that have been sourced from elsewhere and its a one-off defect.

    Presumably, as well as trying cards of different makes, you’ve also tried cards of different capacities and tried reformatting them?

    In any event I’ll keep my fingers crossed for you and will be interested to hear how the situation unfolds.

    Thanks fotdmike,
    but yes I have tried re-formatting the cards and some other make and size, at the moment though it has not done it but only time will tell, oh and using it of course…just so random its hard to recreate the problem which makes it harder to track what is faulty.

    So at the moment it is in proving stage

    Have you looked to see if there is a firmware update for your new Pentax? I’m not saying there is a firmware update to specifically fix this particular issue, but I have read other folks blogs, comments, etc. around the web who say that firmware updates suddenly and miraculously solve errant issues.
