What Is Partition and What Is a GUID Partition Table?

What is partition? What’s the difference between partitioning a country by licitation and succession? And, what is a GUID partition table (GPT)? Let’s answer these questions to learn more. And, hey, there’s even a quiz! So, get cracking! There are lots of different terms for partition, but these five are the most common ones. Hopefully, by the end of this article, you’ll have a better understanding of partition.

Actual partition

Actual partition is a legal separation between joint property owners, where one owner receives his/her own divided portion of the property and retains control over the remaining part. This is the simplest type of partition, especially if the property is divided into separate plots of almost equal value. It can also result in a “conscious uncoupling” of the parties. The court will divide property according to fair market value, as well as any material impairment of one owner’s rights.

Partition by licitation

The process of dividing a property into separate units is known as partition by licitation. It is used when dividing a property into two separate units is impossible or economically inefficient. For example, dividing a property into two separate units would leave a small part that would be worth little compared to the entire property. Likewise, dividing a property into two separate units would mean splitting the proceeds between the co-owners.

Partition by succession

A partition by sale is another type of real estate property division that can be carried out after the death of one party. In a partition by sale, the property is sold and the proceeds are divided between the two owners. This type of partition is usually used when the parties cannot agree on how to divide the property. In other cases, a co-owner may agree to a voluntary partition but still not be willing to give up their ownership rights. In these cases, a party may file a lawsuit and have the court order the partition. This is a court-ordered partition and the court can uphold the decision or overturn it on grounds of public policy or a statute of limitations.

GUID partition table (GPT)

In computer science, a GUID partition table is a data-partitioning style that has increased in popularity since its introduction in 2005. It is a type of file-system partition that supports operating systems that support UEFI (Unified Extensible Firmware Interface Specification) files. This type of partitioning allows users to create unlimited primary partitions in a computer, while retaining the security of MBR. This new style is much more secure than MBR, as its header contains a unique one-byte checksum that protects the integrity of the data-partitioning structure.

AIX partition table (GPT)

The AIX partition table (GPT) is an important part of the operating system, because it allows partitioning up to 9.4 TB of disk space. This table is composed of three parts: the header (which includes the Globally Unique Identifier (GUID)), size, and location. The secondary header contains the Cyclic Redundancy Check (CRC32), which is run by the EFI process during machine startup.

MBR partition table (GPT)

Both MBR and GPT partition tables have their pros and cons. MBR partition tables admit up to 4 partitions each. GPT, on the other hand, admits up to 128 separate partitions. In theory, a GPT partition table allows a computer to use all the disk space it has. However, some users may disagree. If your computer doesn’t support GPT, you should convert it.

MBR vs. GPT differences

If you’re considering a new hard drive, you may be wondering whether you should use an MBR or GPT partition table scheme. While both schemes are good, the former is recommended for smaller drives with older operating systems. On the other hand, GPT is best for larger drives with newer OSs and more partitions. To find out which scheme is right for you, take a look at the table below.

GPT vs. AIX partition table

One of the biggest differences between GPT and AIX partition tables is the placement of the co-existence label. The AIX co-existence label is placed at sector 55. A GPT disk initialized with the co-existence label would not be recognized by AIX utilities. IBM and third party OEMs are working on improving this co-existence check. Veritas is also working on this. But for now, there’s no solution yet.
