Adafruit MicroSD BreakoutBoard+ not working with mbed

I have not been able to connect the Adafruit MicroSD Breakout board+ to my LPC1768. I use the simple Hello World! here: http://mbed.org/handbook/SDFileSystem and am unable to write to the card. I know it is properly formatted and is compatible when using this setup with an Arduino Uno. When I have it all connected to the mbed properly and do not have a card plugged in, the error message it gives me tells me that the 512byte clock timed out. When there is a card inserted however it tells me "No disk, or could not put SD card in to SPI idle state" The microSD cards I have tried are a 4GB Sandisk with a 4 and says microSD HC, and a Kingston 8GB that has a 10 and says MicroSD HC

Not sure about this version, but I ALWAYS had to press reset once, twice, sometimes 3 times, to get it started..

Before you go crazy, also check you are using the newest MBED & SD lib's
