MicroSD not able to initialize often

Using Arduino Storage
10 
  // enable w5100 SPI
  pinMode(10,OUTPUT);
  // now enable the SD SPI at the same time
  while (!SD.begin(chipSelect)) {
  // now disable the w5100 SPI after the SD fail
  digitalWrite(10, HIGH);
  Serial.println("Card failed, or not present");}

That will cause problems. You are enabling the w5100 SPI, then calling the SD.begin() function using the SPI.

I think this is what you said worked.

  pinMode(10,OUTPUT);
  digitalWrite(10, HIGH);

  while (!SD.begin(chipSelect)) {
    Serial.println("Card failed, or not present");
  }
