How to partition hard disks with Disk Management in Windows 10

You might be a little afraid of the process of partitioning the hard drive. And it’s logical to worry, since some damage to the file system, can leave the system unusable. But do not worry, following the instructions I give you, you should not have any problem. In the first place, it is not necessary to download any third-party software, as Windows has its own tool. This is Disk Management and can be accessed from File Explorer. Consequently, the first thing you have to do is press the Win+E combination. Once there, please right-click on This PC and then select Manage.

The Computer Management window will be displayed immediately. Please scroll down to Disk Management.

The disk(s) present on the computer will then be displayed. In this case, we will reduce the disk to create a new partition. Please note that it is necessary to have physical space available on the disk in order to complete the operation. Please select the disk or partition and right-click on it. Then select Shrink Volume.

In this box, you can see the size of the disk before shrinking. In addition to the size available for shrinkage. According to these values, it sets the size of the volume to shrink. After setting the numbers, please press Shrink to start the process.

Run Computer Management

The first thing we have to do is open an application called Computer Management. With this intention, go to the windows explorer by clicking on the folder icon located in the taskbar.

Once there, please select This PC in the left column. Right-click on it and select Manage

A new window with all Computer Management functions will open. Please click on Storage, then on Disk Management

We will immediately see the status of the installed hard disks. We will also see information related to each partition, such as its name, status, and use. To manage partitions, you just need to right-click the mouse on the hard disk. In the menu that unfolds we will see the options to extend, reduce, delete or format the volume. You can also open and explore, mark the partition as active and change the drive letter. Besides, you can enter the properties of the disk. In this case, we will see how to reduce the size of the partition. With this intention, right-click the mouse and select Shrink Volume. According to the amount of memory available on the disk, we can reduce it. The menu is very intuitive, it will indicate the total size before and after reducing it. Once you have made the necessary adjustments, just press Shrink to start the process.

Please note that if you wish to extend a volume, or remove it to create a new partition, just repeat the above process. You just have to change the order to start the process.

Conclusion

We have seen how to manage hard disks in Windows 10. With this intention, we have used the native Windows 10 tool called Disk Management. It’s a very interesting alternative since you don’t have to download files from the internet. Also, it is not necessary to restart the computer to see the changes. All right, that’s it for now. Before I say goodbye, I invite you to review our post on Overwrite in Windows 10. This is a tool to prevent you from recovering information from our hard drive.

The disk stores the information about the partition locations and sizes in an area known as the partition table that the operating system reads before any other part of the disk. Each partition then appears to the operating system as a distinct “logical” disk that uses part of the actual disk. System administrators use different programs to create, resize, delete, and manipulate the partitions.

In this article we will use fdisk program to create partition. Partitioning allows the use of different filesystems to be installed for different kinds of files. Separating user data from system data can prevent the system partition from becoming full and rendering the system unusable. Partitioning can also make backing up easier.

List/view all Disk Partitions in CentOS 8.

fdisk   -l  

In linux all hard disks names show as sda, sdb, sdc etc.

sda means hard disk 1
sdb means hard disk 2
sdc means hard disk 3 and so on..

Hard Disk Partitions names:

Sda> sda1, sda2 etc

sda1 mean partitions 1 of sda(Hard disk 1)
So, sda2 mean partitions 2 of sda(Hard disk 1)

To Check File System Disk Space Usage and mount point of partitions.

df -h    

We will create and configure partition in four steps.

1- Create partition
2- Partprobe
3- Format Partition (Filesystem)
4- Mount Partition

Then we will also see that how to unmount and delete a created partition.

Manage partitions in CentOS 8. Step 1- Create partition

a- Run fdisk command to see disks and their partitions.

In fdisk -l command you have seen that a hard drive /dev/sdb has no partitions, so we will create a new partition on it.

 fdisk –l  

b- Choose desired hard disk

fdisk    /dev/sdb

c- Press m for help.
d- Press p to print partition table.
e- Press n to create new partition.
f- Press p to make primary partition.
g- Press 1 is created first partition on selected disk.
There are 1-4 partition number. We can type any one number from them.
h- Press enter to leave first cylinder as default.
i- Now assign space to partition. Use + to assign space e.g.
+1024M and press enter.
j- Press p to print partition table.

k- Press w to write/save partition.

Step 2- Partprobe

We have created partition but Linux kernel/Operating system did not know that a new partition has been added. To inform operating system about partition table changes. We can do two things. We will use second method it is recommended.

Restart machine (It is not recommended)
Run partprobe command (Recommended)

The partprobe command is used to inform the operating system of partition table changes without restarting the machine.

Note: Always run partprobe command after partition creation.

partprobe
fdisk -l  

Step 3- Format Partition (Filesystem)

We can set file system on partition in two different commands. We can use any of the following.

First Command

mkfs    -t  ext4   /dev/sdb1

mkfs make filesystem
-t to set filesystem type
ext4 It is a filesystem
/dev/sdb1 partition name

OR

Now, second Command

mkfs.ext4  /dev/sdb1

When we press Tab after mkfs we will see all file systems.

Manage partititions on CentOS. Step 4- Mount Partition

First create a mount point (a directory) /disk1 and use mount command to mount /dev/sdb1

a- Make a directory where we mount partition.

mkdir /disk1

b- Now mount partition on created directory.

mount  /dev/sdb1   /disk1

c- See mounted partitions

df –h

d- Mount partition permanently so it can also mount after system reboot.

The configuration file /etc/fstab contains the necessary information to automate the process of mounting partitions. In simple words /etc/fstab file is used to auto mount partitions.

syntax to add partition in /etc/fstab file:

Add partition in /etc/fstab to mount it permanent so if system will reboot partition will not unmount. Run following command.

vi /etc/fstab

then add below lines in in this file.

/dev/sdb1            /disk1      ext4            defaults        0     0

Save and quite.

Above two zero means filesystem will not run repair command on boot time on that partition.

Unmount a partition

If you want to unmount a partition use following command, where /dev/sdb1 will be replaced with your parition.

umount    /dev/sdb1

Mount all partitions. It will read /etc/fstab file and mount all partitions which are configured in that file.

mount    -a

Delete a partition:

df –h

a- Unmount partition. If we does not un-mount, partition will not delete.

umount    /dev/sdb1

b- Choose disk/drive.

fdisk    /dev/sdb

c- Press p to print partitions.
d- Press d to delete partition.
e- Now select partition number, we want to delete. E.g 1 is sdb1
Press 1 and enter
f- Press w to write/save changes.
g- Now run partprobe command.

partprobe

That’s it, You have briefly learned how to create, mount and set filesystems on a partition. We have also mounted, unmount created a partition and also check how to delete it. So, you know how to manage partitions in CentOS 8.
