GUID Partition Table

A

Also designed as a partition table scheme standard for hard drives, the globally unique identifier (GUID) partition table (GPT) makes use of a number of modern techniques to expand on the older MBR partitioning scheme. GPT is commonly used in computers with UEFI firmware. Most modern operating systems now support GPT.

Q

Active partition

A

in MBR disks, the active partition is the partition used to store and boot an operating system. Notice that only primary partitions can be marked active in MBR disks. Another limitation is that only one primary partition per disk can be marked active at one time. In most cases, the C: drive is the active partition and contains the boot and system files.

Q

basic disk

A

A basic disk (the default) contains partitions such as primary and extended as well as logical drives which are formatted for data storage. More space can be added to a partition by extending it into adjacent, unallocated space, as long as it is contiguous. Either MBR or GPT can be used as the underlying partition scheme of basic disks.

Q

Dynamic disk

A
  • Dynamic disks provide features not supported by basic disks. A dynamic disk has the ability to create volumes that span across more than one disk. The size of the partitions can be changed after they have been set, even if the unallocated space is non-contiguous. Free space can be added from the same disk or a different disk, allowing a user to efficiently store large files. After a partition has been extended, it cannot be shrunk without deleting the entire partition. Either MBR or GPT can be used as the partition scheme of dynamic disks.
