An asterisk (*) under GPT row means the disk is of GPT partition style. Unless there is only one disk, you will have to tell DiskPart which disk to manage by using "select disk n" command to give it focus. n represents the number of the disk.

Next, we will take some of the most common commands that Diskpart uses as examples for you to get a further understanding.
Section 1. Most common Diskpart commands on volume in Windows 10/11
Because when selecting a volume, the focus remains on it until you select a different volume, “select volume” command may not be used in each operation. Besides, the examples are performed one after one and the effect of the previous operation will be viewed in the next operation. If you only need to perform one of the operations, you need to select the volume before using the corresponding command.
1. Delete Volume
To delete a volume, please refer to the following command:
▪ list volume
▪ select volume 6 (here take F: drive for example).
▪ delete volume
And then, you will receive a message says: DiskPart successfully deleted the volume.
Note: You cannot delete the system volume, boot volume, or any volume that contains the active paging file or crash dump.
2. Create Partition
To create a partition, please refer to the following command:
▪ create partition primary size=102400
And then, you will receive a message says: DiskPart succeeded in creating the specified partition.
The above command means to create a 102400MB (100GB) primary partition. To create other types of partition, you just need to replace primary with one of the following:
➧Note: To create a partition, there must be unallocated space on the disk.
3. Format Partition
Type list volume command, you will find the new created partition is RAW, which means you must format partition before you can use it. To format a partition, please refer to the following command:
▪ format fs=ntfs quick
And then, you will receive a message says: DiskPart successfully formatted the volume.
The above command means to perform a quick format on the partition. It will be formatted with NTFS file system. To create other file system partition like FAT, FAT32, you just need to replace ntfs with fat or fat32. The label can be any name as you like.
➧Note: DiskPart cannot format 32GB+ partition to FAT32. To format a large hard drive to FAT32, you have to turn to a third-party partition manager.
4. Assign Drive Letter
A partition without a drive letter will be hidden under "File Explorer". To assign a drive letter to an existing partition, please refer to the following command:
▪ assign letter=F (F can be replaced with another letter that has not been used yet).
And then, you will receive a message says: DiskPart successfully assigned the drive letter or mount point.
5. Extend Partition
To extend a partition, please refer to the following command:
▪ extend size=20480
And then, you will receive a message says: DiskPart successfully extended the volume.
The above command means to add 20480MB (20GB) to the volume 6. If no size is given, all of the contiguous unallocated space on its right side will be added.
➧Note: To extend a partition, there must be contiguous unallocated space on its right side.
6. Shrink Partition
To shrink a partition, please refer to the following command:
▪ shrink desired= xxxxxx
And then, you will receive a message says: DiskPart successfully shrunk the volume by 39GB.
➧Note: You can reduce the size of a volume only if it is formatted using the NTFS file system.
7. Mark Partition as Active
To mark a partition as active, please refer to the following command:
And then, you will receive a message says: DiskPart marked the current partition as active.
