There are many reasons why this could happen:
* You used a Kingston (or other cheap) SD card with a file system other
than FAT32
* The partition is not aligned to 4 MB
* The cluster size is less than 16 KB
* You have multiple partitions on the card
If any of these are true, you have destroyed the card by writing a
lot of data to it.
