Over the years I have accumulated a lot of old SD cards, today I decided to have a sort out of the ones I was never going to use. I was running them through a card speedtest program when I found one that wouldn't even show up on the PC and seemed to be completely dead. Before I put it in the bin I decided to take it apart (I tend to do things like that !) and was very surprised at what I found.
This was a normal looking cheapie full sized SD card.
Inside was a micro SD card, this was not an adaptor, the micro SD was sealed inside and not even soldered in position.
Just out of interest I put the micro SD into a card reader and it worked so it was all down to poor connections inside the larger case.
I wonder how many of the fake re-labelled cards are built in this way.
This what a proper full sized SD card looks like inside.

Over the years I've used exactly two brands of SD cards. Those from Canon (still have a 16 MB one for sentimental sake) and SanDisk.
Yep, do only purchase reputable brands and then only from reputable dealers. e.g. Amazon is known to to have fake cards.
