You have received instructions to convert a basic disk to a GPT disk.
Which of the following is TRUE with regards to GPT disks? (Choose all that apply.)
A.
To convert a basic disk to a GPT disk, the disk must not contain any partitions or volumes.
B.
You can convert a basic disk to a GPT disk, regardless of partitions or volumes.
C.
GPT is required for disks larger than 2 TB.
D.
GPT is required for disks smaller than 2 TB.
E.
The GPT partition style can be used on removable media.
F.
GPT disks make use of the standard BIOS partition table.
Explanation:
A)
For a drive to be eligible for conversion to dynamic, all basic data partitions on the drive must be
contiguous.
C)
GPT allows a much larger partition size greater than 2 terabytes (TB) D. 2 terabytes is the limit for
MBR disks.
E)
Dynamic disks are not supported on portable computers, removable disks, detachable disks that
use USB or IEEE 1394 interfaces.
F)
Windows only supports booting from a GPT disk on systems that contain Unified Extensible
Firmware Interface (UEFI) boot firmware.
Master boot record (MBR) disks use the standard BIOS partition table. GUID partition table (GPT)
disks use unified extensible firmware interface (UEFI). One advantage of GPT disks is that you can
have more than four partitions on each disk. GPT is also required for disks larger than 2 terabytes.
Portable computers and removable media.
Dynamic disks are not supported on portable computers, removable disks, detachable disks that use
Universal Serial Bus (USB) or IEEE 1394 (also called FireWire) interfaces, or on disks connected to
shared SCSI buses. If you are using a portable computer and right-click a disk in the graphical or list
view in Disk Management, you will not see the option to convert the disk to dynamic.
Dynamic disks are a separate form of volume management that allows volumes to have
noncontiguous extents on one or more physical disks. Dynamic disks and volumes rely on the Logical
Disk Manager (LDM) and Virtual Disk Service (VDS) and their associated features. These features
enable you to perform tasks such as converting basic disks into dynamic disks, and creating faulttolerant volumes. To encourage the use of dynamic disks, multi-partition volume support was
removed from basic disks, and is now exclusively supported on dynamic disks. GPT disks can be
converted to MBR disks only if all existing partitioning is first deleted, with associated loss of data.
Q) What happens when a basic disk is converted to dynamic?
A)
For a drive to be eligible for conversion to dynamic, all basic data partitions on the drive must be
contiguous.
If other unrecognized partitions separate basic data partitions, the disk cannot be converted. This is
one of the reasons that the MSR must be created before any basic data partitions. The first step in
conversion is to separate a portion of the MSR to create the configuration database partition. All
non-bootable basic partitions are then combined into a single data container partition. Boot
partitions are retained as separate data container partitions. This is analogous to conversion of
primary partitions.
Windows XP and later versions of the Windows operating system differs from Windows 2000 in that
basic and extended partitions are preferentially converted to a single 0x42 partition, rather than
being retained as multiple distinct 0x42 partitions as on Windows 2000.
