A partition table is described as a table maintained on disk by the OS, describing the partitions on that disk. The terms partition table and partition map are most commonly associated with the MBR partition table of a Master Boot Record. It also usually refers to other formats that divide a disk into partitions, including GPT (GUID Partition Table), APM (Apple partition map), and BSD disklabel. - From Wikipedia

With the partition table, the computer can detect the existing hard drive, and users can create, resize, and delete partitions on the disk. The partition table is usually created while installing an operating system on Windows and Mac computers. 

However, when the table on a disk is corrupted, you can't use or access the saved data in the partition anymore. However, you can check how to recover the partition table by reading the following parts, and we'll help you recover the lost or deleted partition table and recover data from the deleted partition.
