Windows 7: WD External Hard Drive Not Showing on My PC

MBR
GPT

The Master Boot Record (MBR) partitioning scheme, widely used since the early 1980s, imposed limitations for use of modern hardware. A major deficiency is the limited size of 32 bits for block addresses and related information. For hard disks with 512-byte sectors, the MBR partition table entries allow a maximum size of 2 TiB (2 512 bytes).

In the late 1990s, Intel developed a new partition table format as part of what eventually became the Unified Extensible Firmware Interface (UEFI). As of 2010, the GUID Partition Table forms a subset of the UEFI specification.[2] GPT uses 64 bits for logical block addresses, allowing a maximum disk size of 264 sectors. For disks with 512-byte sectors, the maximum size is 9.4 ZB (9.4 10 bytes) or 8 ZiB (264 sectors 29 bytes per sector)

A disk is divided in tracks (same radius) and each track is divided in sectors (angle)

if you don't mind; I wanted to tell you that I saw all those 3 links which you sent, but.... I still did not understand it clearly the theory of MBR, GBT and the sectors...

so, if you can; just no offence, can you explain those more to me with respect to my issue of the HArd drive which I possess and over all how they are related into Hard Drives and so on..
