• How to recover partition table?

    • Most of us need to separate our hard drives into several partitions to manage our multiple data for different usage. But we accidently encounter a circumstance that when we try to access one of the partitions a dialogue box pops up: “Disk Disk/Drive is not Formatted…" or PC shows no partition.

    • The definition of partition table
    • A partition is part of a hard drive, or a section, it is an independent storage area or hard drive managed by operating system. To partition a hard drive, you may use “fdisk” command or partition tools from the third party supporters. Once you partition a hard drive, the partition table must be rewritten. Because the partition table is a list displays the layout of which parts of the table are reserved for file systems.

    • Partition table is contained inside the MBR (Master Boot Record) which means partition table is located at the first sector (cylinder 0, head 0 and sector 1, MBR) of each hard disk. It stores all the information about a hard drive, for example, the sizes and the locations of partitions and the address where each partition begins. Normally, a partition table is only 64 bytes long and it is limited to a maximum of 4 entries which means only 4 primary partitions can be created on one hard drive. However, more Logical drives could be created in the Free Space until you either ran out of drive letters or the Free Space was exhausted.
