Starting to wonder about the SD card in the Pi..

This afternoon I decided to start fiddling with one of my Raspberry Pi’s, I’ve been collecting bits of hardware here and there for a small scale home automation project using some X10 gear. Small problem though, the thing won’t boot now, the SD card seems to be corrupt and won’t take a new image.  Not just one card but two out of three.

The cards are a year or so old, purchased them all at the same time from a reseller on Amazon. Turns out, this may not have been a wise idea.  After spending some time searching online for similar issues, I’ve found that counterfeit SD cards is a pretty big thing.  Not sure if that’s the case here, they all have different serial numbers, but I’ll be reaching out to the Kingston folks later on to see if the cards can be verified.

Using a smaller capacity card seems to work fine, so no issues with the reader on my laptop or the Pi.  SD card corruption has happened to me in the past when the Pi abruptly lost power without shutting down first but imaging it again was never a problem.

I think from here forward that purchasing direct from the manufacturer or a trusted reseller is the best way to go, google ‘fake sd card’ and check the results for yourself. In the meantime, card number three has an image and I’m going to try and start working on randomly blinking lights on and off in the house.  Eventually I may try to hack my coffee maker.

Oh, and fun fact: raspberrypi.org is powered by WordPress. 🙂

  1. Even if Kingston verifies the cards, they still could be from a bad batch. Cold solders or other issues on the assembly lines can ruin whole batches, and I have heard from a friend at one of the larger companies that it’s generally considered cheaper to replace bad products as reports come in than to halt a production run.

    • When I worked for another company, we ran into a similar issue with a large computer manufacturer. New laptops were failing left and right because of a problem with the motherboards, as soon as their tech support got the serial numbers they knew right away what the issue was.
