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 VirtualDisk Service (VDS) and their associated features. These features enable you to perform tasks such as
converting basic disks into dynamic disks, and creating fault-tolerant 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.
