The document discusses disk management, a Microsoft Windows utility introduced in Windows XP, which allows users to manage disk drives and their associated partitions. It contrasts the Master Boot Record (MBR) system with the newer GUID Partition Table (GPT), highlighting MBR's limitations and GPT's advantages, such as larger disk support and more partitions. Additionally, it covers the concept of Virtual Hard Disks (VHD) and the characteristics of basic disks.

2. Disk Management
• Disk Management is a Microsoft Windows utility
first introduced in Windows XP as a replacement
for the fdisk command.
• It enables users to view and manage the disk
drives installed in their computer and the
partitions associated with those drives.
• As can be seen in the picture below, each drive is
displayed followed by the layout, type, file
system, status, capacity, free space, % free, and
fault tolerance.

4. Master Boot Record (MBR)
• The Master Boot Record (MBR) is the information
in the first sector of any hard disk that identifies
how and where an operating system is located so
that it can be loaded into the computer's main
storage or random access memory.
• MBR does have its limitations. For starters, MBR only
works with disks up to 2 TB in size.

5. Master Boot Record (MBR)
• MBR also only supports up to four primary partitions
if you want more, you have to make one of your
primary partitions an “extended partition” and
create logical partitions inside it. This is a silly little
hack and shouldn’t be necessary.

6. Global Partition Table (GPT)
• GPT is a newer standard that’s gradually replacing
MBR.
• GPT, in turn, replaces the old MBR partitioning
system with something more modern. It’s
associated with UEFI.
• It’s called GUID Partition Table because every
partition on your drive has a “globally unique
identifier.

7. Global Partition Table (GPT)
• GPT doesn’t suffer from MBR’s limits.
• GPT based drives can be much larger, with size
limits dependent on the operating system and
its file systems. GPT also allows for a nearly
unlimited number of partitions.

8. Virtual Hard Disk (VHD)
• Virtual hard disk (VHD) is a disk image file
format for storing the complete contents of a
hard drive.
• The disk image, sometimes called a virtual
machine, replicates an existing hard drive and
includes all data and structural elements. It
can be stored anywhere the physical host can
access.

9. Basic Disk
• A physical disk that contains primary
partitions, extended partitions, or logical
drives. Basic disks can be accessed by all
versions of Windows, MS-DOS, and Windows
NT.
• Basic disks can contain up to four primary
partitions, or three primary partitions and an
extended partition with multiple logical
drives.
