It took about an hour to get the four 8GB dumps from the two 16GB NAND chips from a 32GB SD card. It will take at least two more hours to run the ECC check and correction before we can move forward with the virtual reconstruction and file system recovery. The entire process could take several days to complete.
It is amazing how much more complex a little SD card can be to recover than a much larger and more expensive hard drive.
