There is no extended partition or logical partitions on a GPT disk since there are no limits on how many primary partitions you can create. This is what differs a GTP disk from an MBR disk remarkably. For example, under Windows, each partition entry is 128bytes, thus, you can create a maximum number of 128 (32*512/128=128) partitions under Windows. However, the number of the partition you are able to create will be limited by the operating system. Theoretically, you can create unlimited partitions on a GPT disk. Partition Entriesįrom the third sector to the thirty-fourth sector (32 sectors in total) are the partitions entries. When CRC detects data corruption, it will attempt to recover the data using the backups stored at the end of the disk. It defines the location and size of the partition entries that consist of the partition table and the cyclic redundancy check (CRC32) checksum that is used to verify the integrity of the GPT header. The second sector on a GPT disk stores the primary GUID partition table header. Different from the one on an MBR disk, the protective MBR on a GPT disk serves the function of preventing tools that only supports MBR disks from misrecognizing and overwriting GPT disks. The first sector on a GPT disk is also the MBR sector. Compared with the MBR partitioning scheme, it's more flexible and has better compatibility with modern hardware.
GPT, GUID Partition Table, is the newer standard compared to MBR first introduced as part of the UEFI initiative. That means if you have a disk larger than 2TiB with the MBR partition style, you can only use at most 2TiB space on it. The most obvious disadvantage of an MBR disk is that it only works with a maximum size of 2TiB(≈2.2TB) on a disk. (Within the extended partition, you can create multiple logical drives.) If you prefer more than four partitions on the disk, you should make one primary partition an extended partition to create logical partitions. Since the disk partition table is 64bytes in total and the information of each partition is 16bytes, you can create at most four primary partitions. You can only use the extended partition to create multiple logical drives to utilize the space. Unlike a primary partition, an extended partition is a "concrete" storage unit with a drive letter and file system. Excluding the space taken by primary partitions, the space left on a disk is called an extended partition.

Primary partitions are those you can install the operating system on and make active in order to boot the computer from it. Partitions can be categorized as primary partitions and extended partitions on an MBR disk.
To use a disk for data storage, you need to divide it into chunks called partitions. Thus, when it's corrupted, you won't be able to use the disk until you rebuild MBR. The information in this sector describes how the partitions are organized on the current storage device.

It takes up 512bytes and contains the master boot code (446bytes), disk partition table (DPT, 64bytes), and the boot signature (2bytes) which marks the end of the MBR sector.
The first sector on both an MBR disk and a GPT disk is the MBR sector. Here is a simplified structure of an MBR disk. It's named after the boot sector located at the very beginning of a drive (the first sector) called MBR.

MBR, Master Boot Record, is an older disk-type first introduced with IBM PC DOS 2.0 in 1983.
