HI,
I purchased a self-assembly Data Logger Shield Kit a few months ago and have only gotten around to assembling it this week. The assembly went well, and the first trial for RTC was successful also. When I try CardInfo, the serial monitor is returning "SD Card Not Initialised". It does this whether there is an SD Card in there or not. I have tried two 4GB SD Cards, both source from Adafruit, and formatted both with SD Formatter V3.1, with no success.
I have continuity on the SD Card Holder pins I can test with multimeter, and the GND pins all match as they are supposed to.
I believe I assembled the board correctly - see video here http://www.youtube.com/watch?v=OlUvreFuPns
Has anyone got any ideas on where the problem can relate to?

Re: Troubleshoot Data Logger Shield SD Card Not Initialised
It is a little hard to see in the video, but some of the SD card holder solder joints look suspect. Testing with a multimeter is not conclusive - since poking an intermittent connection with a probe typically makes it conductive. Re-work any that are not smooth and shiny or have not flowed well onto both the pin and the pad.

Truly awesome support - you were correct in identifying the solder problem - I did not have enough on pin 7 - the connection looked good but no solder appeared to have flowed around connection - reflowed and the board is working well now.
Many thanks for your help.
