A partition table is a 64-byte data structure that stores the basic information of your computer's operating system. The basic information stored is inclusive of how many partitions are available, how big each of them are and where they are located in the hard disk drive. A partition is a logically independent section of the hard disk drive and each disk can have different number of partitions. The partition table consists the first four partitions on a hard disk drive, which are collectively known as the "primary partition". Any extra partitions in the disk is known as the "extended partition"
This sounds a lot for a non-technical person. To make the situation a bit more complicated, there are two categories of partition tables i.e. Master Boot Record (MBR) and GUID Partition Table (GPT). MBR contains a primary partition, an extended partition and a logical path. Most operating systems use MBR, but there is a growing popularity for GPT this is because MBR has a limited memory of 2TB, while GPT allows up to 10 billion terabytes (theoretically).
To ensure that all partitions of the hard disk drive are functioning properly, the role of the partition table is crucial. It used by the computer's operating system to find partitions and files on the disk.
A corrupted or damaged partition may cause the partition table of a computer to be damaged or lost. This will render the operating system of your computer to be useless it will not be able to locate data and files on the hard disk drive without the partition table. This will amplify the damage that is already there.
Once you detect that the partition table is damaged or lost, you will need to recover the partition table swiftly. Since the partition table informs the operating system information about each partition, its size and files stored inside it, any damage and loss will interfere with the operating system's normal functions.
