Thank you so much Saikee for your detailed explanation. Sorry for the 3 days gap in replying to your post... I was actually reading up on hard drive geometry so I can make better sense of your reply.

It appears the whole track or the first head, equal to the number of sectors per head times sector size, is reserved for the MBR usage.
You mean 'equal to the number of sectors per TRACK times the sector size.
Because from what I gleaned, head is simply the physical head to read sectors on the platter. The actual sectors are on the tracks. Right.

as Manufacturer A might opt for 16 sectors per head while another manufacturer B chose 32 sectors per head
again, you mean 16 sectors per track, 32 sectors per track.. right?

Code:
dd if=/dev/sda of=dragons-enclave.bak bs=512 skip=1 count=61
The above command will skip the first sector (which is the true MBR), start and the 2nd sector and go all the way upto 62nd sector. Am I right?

Therefore if you find a dragon there it is just its carcass.
Thus, if I turn the carcass into ash by the following command:
Code:
dd if=/dev/zero of=/dev/sda bs=512 skip=1 count=62
it shall zero out everything between the 1st sector (true MBR) and the 63rd sector. And after doing so, if the Operating System boots just fine, then there is nothing of value there, indeed just some carcasses laying around... Right?
