Kindly suggest me a safe and secure solution.” “I bought a new hard drive and want to create partitions in it. All I want to create GPT partition.
Master boot record (MBR) is the boot sector standard that supports a maximum primary partition of 2TB. MBR allows four primary partitions per drive. The globally unique identifier (GUID) partition table standard (GPT) can support enormous partitions with a theoretical maximum of 9.4ZB (9.4 x 10 to the 24th bytes).
Jun 06, 2012 · GUID Partition Table (GPT) is a boot sector technology poised to replace the venerable Master Boot Record (MBR) principally because MBR has a maximum capacity of 2 TB for a single partition (some single disks have reached 3 TB). Installing Windows on a GPT is a bit tricky because Windows wants to default back to MBR.
Mar 13, 2017 · It is really easy to hit 2 TB (using 512-byte sectors) partition size limit when using MBR disk partition table.

Aug 30, 2011 · One more point: gdisk says that the partition table is completely intact, which means that the backup data appear at what gdisk thinks is the end of the disk (at the 746.5 GiB mark). When you fix the apparent disk size issue, you may need to use the "e" option on gdisk's experts' menu to move the backup data back to where they belong.
You can choose MBR (Master Boot Record) or GPT (GUID Partition Table) as its partition style. The maximum size of an MBR disk is 2TB (Terabytes) and it can hold up to 4 primary partitions. Unlike MBR disk, GPT disk doesn't have such limitations.

The protective MBR occupies one 512-byte sector, the GPT header occupies the next sector, and the partition table entries follow. Then at sector 34 there’s a 3KB gap so that the first partition starts on a 4KB boundary (i.e. 20KB from the start of the disk).
I would like to be able to limit the root partition's size (leaving free space on the SSD) and increase the swap partition's size, using a GPT disk layout with 4k-aligned partitions.
