Issue: No disk, or could not put SD card in to SPI idle state error

Hello mimi3,

I had used your example code as per the changes you had made the compliation error has been corrected. But now i have a new issue that i get error as "No disk, or could not put SD card in to SPI idle state ". I had tried changing the frequency and supply voltage of SD card but could acheive any change.So could you please provide me where is the problem araising from.

Error :
