Hi guys,
Yet another simple thing that I can’t seem to fix:
the code
if (sdCard.Mount())
{
Debug.Print("sd root dir: " + sdCard.StorageDevice.RootDirectory);
sdCard.Unmount();
}
else
{
Debug.Print("Failed to mount the SD card!");
}
the output

Failed to mount the SD card![/quote]
I’ve found a mix of examples, but something easy as mounting the SD card fails …
Any help would be much appreciated 
@ thisway.ro - Can you verify that sdCard.IsCardInserted is true and that IsCardMounted is false? Can you try to format the card on your computer?
@ John - yes, IsCardInserted has the value 1 and IsCardMounted the value 0. I have formatted it as FAT without any different result
@ Dat - the connection is good 
I have changed the code a bit, but no luck:
while (!sdCard.IsCardMounted)
{
Debug.Print("SD card not mounted yet ...");
sdCard.Mount();
Thread.Sleep(1000);
}
if (sdCard.IsCardMounted)
{
Debug.Print("sd root dir: " + sdCard.StorageDevice.RootDirectory);
sdCard.Unmount();
}
else
{
Debug.Print("Failed to mount the SD card!");
}

@ thisway.ro -
Make new project, non-gadgeteer, deploy tiny code below, it can check what problem is.
using System;
using System.Threading;
using System.IO;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using Microsoft.SPOT.IO;
using GHI.IO;
using GHI.IO.Storage;
class Program
{
static SDCard sd_card = null;
static InputPort button = new InputPort((Cpu.Pin)xx, false, Port.ResistorMode.PullUp);
public static void Main()
{
while (button.Read())
{
Thread.Sleep(100);
Debug.print("Wait for pressing the button");
}
sd_card = new SDCard();
// if exception here:
// + Check wire or connection
// + Try diffirent card.
sd_card.Mount();
// if exception here:
// + reduce SD clock
// + Format FAT32 by PC
Debug.Print("SD Mounted");
}
