Why is there not one card reader capable of using SPI or atleast enabled??..I do have sd card adapters that are spi but trying to get an image is no fun...Does anyone think i could just inject some commands with buspirate to enable SPI then use the same reader to make an dump...This is of course only if SPI is working and not regular mode..Thanks for any input!!

At initial power-up or card insertion, the host device selects either the Serial Peripheral Interface (SPI) bus or the one-bit SD bus by the voltage level present on Pin 1. Thereafter, the host device may issue a command to switch to the four-bit SD bus interface, if the SD card supports it.
eMMC also does not support the SPI-bus protocol.

Pretty sure my PC3k Flash Card adapter has this option.

There are some resources out there such ashttp://www.microchip.com/forums/m530149.aspxhttp://nerdclub-uk.blogspot.com.au/2012/11/how-spi-works-with-sd-card.htmlhttp://elm-chan.org/docs/mmc/mmc_e.html
what is it specifically you want to do?
If the SD card is failed and you think you might be able to go through a different interface, this is probably unlikely.
