title: Bad block detection in SD card using SPI interface?
body: <p>I know that SandDisk Micro SD cards have bad block detection and re-mapping capability.  The default mode for an SD card is the 4 bit SD interface. When using the SPI interface does anyone know if the SD card will still do this automatic bad block detection and re-mapping? Based on my reading the SanDisk OEM Product Manual</p>
  
  <p>"The SPI Mode is a secondary communication protocol for cards in the SanDisk
  microSD Card Product Family. This mode is a subset of the SD Protocol, designed to
  communicate with an SPI channel, commonly found in Motorola and other vendors'
  microcontrollers. Detailed information about SPI Mode can be found in Section 7 or
  the SDA Physical Layer Specification, Version 3.01."</p>
  
  <p>This does not seem to clarify my doubt. Does anyone know the answer?</p>
