For an MBR partition, what is the maximum disk size a partition can be?

Explanation:
MBR partitions are limited by a 32-bit field that stores the partition size in sectors. That means the maximum number of sectors a partition can have is 2^32. If the disk uses the common 512-byte sectors, the largest possible partition size is 2^32 × 512 bytes, which is about 2 TiB. So you’ll typically see the practical limit described as roughly 2 TiB for an MBR-partitioned disk. If your sector size were different (for example, 4 KiB), the math changes accordingly (2^32 × 4096 equals about 16 TiB), but the underlying constraint is the 32-bit LBA addressing. For disks larger than this, GPT is used because it supports vastly larger addresses.
