Only adding some info:
If we have the sector number as a 32 bit integer, instead of 16 bit
integers, we would have:
Old: 2^16 => 65536 * 512 = 33554432 bytes = 32768 Kbytes = 32 Mbytes
New: 2^32 => 4294967296 * 512 = 2199023255552 bytes = 2147483648 Kbytes
= 2097152 Mbytes = 2048 Gbytes = 2 Tbytes.
Wow!
