As it is known to user, user can resize partition to better make use of disk space. Based on Itanium, GPT is a disk partition architecture which can expand EFI. GPT possesses more advantages in comparison with MBR. However, user still needs a professional disk management program to resize GPT disk partition. As far as I know, MiniTool Partition Wizard Server Edition could be the unique choice for user to resize GPT disk partition.
What is GPTdisk?
In computer hardware, GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk. Although it forms a part of the Extensible Firmware Interface (EFI) standard (Intel's proposed replacement for the PC BIOS), it is also used on some BIOS systems because of the limitations of MBR partition tables, which restrict a disk partition's size to a maximum of 2.2 TB (2.2 × 1012 bytes). GPT allows for a maximum disk and partition size of 9.4 ZB (9.4 × 1021 bytes).
MBR-based partition table schemes insert the partitioning information in the master boot record (MBR) (which on a BIOS system is also the container for code that begins the process of booting the system). In a GPT, partition table information is stored in the GPT header, but to maintain compatibility, GPT retains the MBR entry as the first sector on the disk followed by a primary partition table header, the actual beginning of a GPT.
Like modern MBR, GPT uses logical block addressing (LBA) in place of the historical cylinder-head-sector (CHS) addressing. Legacy MBR information is contained in LBA 0, the GPT header is in LBA 1, and the partition table itself follows. 64-bit Windows operating systems reserve 16,384 bytes (or 32 sectors) for the GPT, leaving LBA 34 as the first usable sector on the disk.
User would meet above interface after running this disk management program. In this interface, all disk partitions are displayed and user should select and right click desired partition and then click "Move/Resize".
This Windows is for adjusting partition size and position by dragging the left and right arrow or directly entering accurate values in the blank. At the same time, user is recommended to check the red zone to insure the safety of partition. After that, click "OK" to enter next step.
Lastly, click "Apply" at the top left corner to execute pending execution.
This is all process on how MiniTool Partition Wizard Server Edition resize GPT disk.
