Partitioning Disks in Windows 7 tutorials

In this Module there are two different types of Partitioning Disk

1-MBR Disk

2-GPT Disk

 

To install a disk in a computer we need to select one of the two partitioning disk. The reasons to partition a disk is

  • Separate operating system files from data and user files.

  • Place applications and data files in the same location.

  • Put cache, log, and paging files in a location separate from other files.

  • Create multiboot setup environments.

 

  • To do a disk related tasks like creating and formatting partitions, assigning drive letters etc. we can use disk management or converting disks from one partition scheme to the other.

 

MBR – Master Boot Record

 

  • The MBR is created when the Hard disks are partitioned.

  • It is written on first sector of the hard disk,

  • It contains the partition table for the disk, how logical partitions are stored, its location, type of File system organized on disk drive and a small amount of executable code known as the master boot code.

 

Keep following points in mind when you install Operating System using MBR.

  • The concept of MBR was introduced in 1983.

  • It consists of 512 or more bytes located in the first sector of the disk.

  • MBR support maximum 4 partitions on each disk and of 4 partition one could be Active Partition to boot system.

  • Of all 4 partitions, all can be Primary Partitions or maximum 1 Extended Partition.

  • Extended Partition can contain multiple Volume inside.

  • Maximum partition size is 2 Terabytes, that is 2.20 x 1012 bytes.

  • No redundancy, if MBR partition becomes corrupt or incure damage, it leads to single point of failure and operating system might become unbootable.

  • With new operating system demanding more space than 2 terabytes, it became a limiting factor since 2010.

  • Due to above limitations, MBR partitioning system is superseded by GUID (GPT) system. A GUID (GPT) can coexist with MBR in order to provide backward compatibility for older system.

 

GUID – GPT Disk.

  • In computer hardware GUID Partition Table (GPT), is a standard layout of Partition table on a physical hard disk.

  • It is a part of UEFI (Unified Entensible Firmware Interface) standard. It is Intel’s proposed replacement for PC BIOS.

  • You can implement GPT based disk in Windows Server 2008, Windows Vista, Windows 7 and Windows 8.

  • You cannot use GPT partition on Removable disk.

  • GPT support maximum 128 partitions per disk.

  • Maximum disk volume size is 18 Exabyte. Each Exabyte is equal to one quintillion, that is 10 raised to 18 bytes. You can say 1 Exabyte equals one billion gigabytes or you can also say 1 Exabyte equals one Million Terabytes.

  • As of now we don’t have hardware or disk with such a large volume.

  • GUID GPT disk check for Cyclic Redundancy Check (CRC) duplicates and protect GPT disk.
