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.
