As MBR uses 32-bit to record the partition, each partition can only go up to a maximum of 2TB in size.

How can this be mathematically explained?


From the Wikipedia entry:

[The] maximum disk size supported on disks using 512-byte sectors (whether real or emulated) by the MBR partitioning scheme (without using non-standard methods) is limited to 2 TB.

2TB = 2*1024*1024*1024*1024 = 2^41 = 2^32 * 2^9, and 2^9 is 512.
