First of all, thanks for everyone replied.

One article called "The master boot record (MBR) and what it does" states: 
"The master boot record is always located at cylinder 0, head 0, and sector 1, the first sector on the disk".
My current problem is that I can't see ANYTHING in the first sector on my disk (SD card), as well as in the following 248 sectors, nothing but all zeroes. Yes, I can see the volume boot sector (at rather a weird location 249), both file allocation tables, root directory and so on...
I tried both FAT16 and FAT32 on this card, and the result is just the same: boot sector number 249.
