硬碟使用MBR 分割格式，為什麼最大只能支援到 2.2 TB ?  若是改用新的UEFI GPT分割格式可以支援使用多大容量的HDD?
BIOS systems with MBR disks use 32-bit values
to describe the starting offset and length of a partition. Due to this size limit, MBR allows a maximum disk size of approximately 2.2 TB and a maximum of four primary partitions.

UEFI supports the GUID Partition Table (GPT),
a more flexible partitioning scheme. GPT disks
use 64-bit values to describe partitions, allowing
larger partitions. GPT also fixes other issues
related to MBR (data integrity, backup tables,
maximum number of partitions, …).
Using 64-bit values, GPT can handle disks of up
to 9.4 x 1021 bytes or 9.4 zettabytes (ZB).
