How to Create, Format a disk partition?

So, in this PC we have tow hard disks. You must select the exact disk that you want to work with.

To select disk 1, just type ‘select disk 1’ and press enter, then type ‘list disk’ to see whether the disk has selected or not.

Now clean the disk by ‘Clean’ command and create a partition with create partition command. ‘Create partition primary size=40000’ this command will create a 40 GB primary partition from disk 1.

To check the created partition type ‘List vol’ command. The command will list all volumes.

The Volume 3 is the newly created partition. It is selected and ready to format it.

Type ‘format fs=ntfs quick’ to format the partition, and type ‘list vol’ to see the formatted partition with NTFS file system.

Now you have learned creating, formatting and some diskpart commands.
