You missed a few! :-)
The actual number of 512-byte blocks is 979964 - 63 + 1 = 979902.
Fdisk always reports 1k blocks in the "Blocks" column. Or if an odd
number of 512-byte blocks, the number of 1k blocks with a '+' afterwards.
Plus, you want the mbr as well, plus whatever is between blocks 0 and
63, so better option might be:
dd if=/dev/hda of=parttbl+mbr+boot.backup bs=512 count=979965
