Can someone help me with SD card reading problems I'm having, its a very strange one.
I've tried to use two different SD card readers with the same results, here is whats happening.
Using the standard Cardinfo sketch I receive the following message " initialization failed. Things to check...."
by chance I accidentally pulled the Gnd wire out of the socket, when I put it in the serial screen displayed the message you should get when a successful display of the card information is presented ! but when I refresh the serial display again I Just get back to the error message. If I remove the Gnd wire and re insert it shows the correct card data !
The stand alone SD Card reader is a Catalex type, the other is part of a display + SD card unit .
I've tried 1k resistors in series but it fails to read the card in any way, the only other thing I can think of is the libraries, but I'm using the standard ones. After hours of head scratching I don't know where to try next.
