How to increase disk size in VirtualBox [Guide]
Mar 17, 2024 am 10:10 AMWe often encounter situations where the predefined disk size has no space to accommodate more data? If you need more virtual machine hard disk space at a later stage, you must expand the virtual hard disk and partitions. In this post, we will see how to increase disk size in VirtualBox.
Increase disk size in VirtualBox
It is important to note that you may want to back up your virtual hard disk files before performing these operations, as there is always the possibility of something going wrong. It is always a good practice to have backups. However, the process usually works fine, just make sure to shut down your machine before continuing.
There are two ways to increase the disk size in VirtualBox.
Let’s talk about it in detail.
1]Expand the disk size of VirtualBox using the GUI
Oracle provides a tool called Virtual Media Manager in VirtualBox that allows us to edit your computer. Follow the steps mentioned below to expand the disk size.
Even if the disk size increases, the partition size will not change automatically. You need to extend the partition on the disk to use the extra space. To do this, you need to log into the virtual machine and use the disk management tool to extend the partition.

2]Extend VirtualBox disk size using CLI
First, proceed to shut down the virtual machine. At the same time, make sure to turn off the device and set it to PowerOff, not Saved. Now, in order to change the disk size, we need to use the VBoxManage command.
Before modifying the virtual disk file, if you use the snapshot feature in VirtualBox, be sure to delete all associated snapshots. This ensures that you are modifying the correct virtual disk file and everything will run normally afterwards.
Open Run, type "delete" and press Enter. This will open the command prompt for you, next, you need to switch to VirtualBox’s program files directory using the command mentioned below.
cd "C:Program FilesOracleVirtualBox"
Now, we need to find out your folder, to do this, open File Explorer and go to the following path.
C: USERS username VirtualBox VM
Note: Please make sure to replace username with the username of the virtual machine host.
After navigating to this location, open the VM's folder and look for files with the .jobs extension. Now, note the name and location of the file. Finally, run the following command to increase the disk size to 50 GB or 51200 MB.
VBoxManage modifyhd "C:UsersyusufVirtualBox VMFedora. vdi"——resize 51200
If this command does not work, please run the following command because VirtualBox 6.0 launched in 2019 does not support the above command.
VBoxManage modifymedia disk "C:UsersyusufVirtualBox VMFedora.vdi"——resize 51200
This will do the job for you. However, if you get an error saying VBOX_E_NOT_REMORTED, check to make sure you didn't shrink the drive because the --resize command takes the final size as input. So if your disk is currently 16GB in size and you are trying to resize it to 8GB, it won't work.
You will also need to extend the partition to use this extra space. There are many ways to do the same thing, try using Paragon Partition Manager, it's a free tool.
that's all!

What is the maximum disk size in Virtual Box?
Graphical User Interface (GUI) allows you to create hard drives up to 2TB. For larger disks, you can use the VBoxManage command line tool. Just open a command prompt, go to the VirtualBox location, and use the VBoxManage command as shown earlier.

Windows 11 has strict requirements, and after struggling to obtain that storage, losing your hard drive and data would be a shame. Well, we have good news that can help you buffer against hard drive failure. Using built-in Windows tools, you can copy all your data from one drive to another. This way, if one drive fails, you can mirror and rebuild the original data on the replacement drive. Can Windows 11 do RAID? With Windows Storage Spaces feature, you can perform RAID on Windows 11. This feature allows you to create multiple virtual disks using a hard drive connected directly to your computer without degrading performance. Benefits of Raid: Reduce the cost of disk

Drive failure is a serious issue that may render your files unrecoverable or your boot drive non-working, so that is why many users choose to create a mirrored volume on Windows 11 as a way to prevent this. If you're not familiar, a mirrored volume is an exact copy of another drive that can be used as a backup in the event of a disk failure. It's a great backup solution, and today we'll show you how to create it on your PC. What are the prerequisites for setting up a mirrored volume? Two dynamic disks of similar size. The mirror drive can be larger than the source drive. RAID support is available on almost every modern PC. The mirror drive should be unallocated and do not have any volumes. How to create a mirrored volume in Windows 11? 1.Use

If you want to convert a dynamic disk to a basic disk in Windows 11, you should create a backup first as the process will erase all data in it. Why should you convert dynamic disk to basic disk in Windows 11? According to Microsoft, dynamic disks have been deprecated from Windows and their use is no longer recommended. Additionally, Windows Home Edition does not support dynamic disks, so you will not be able to access these logical drives. If you want to combine more disks into a larger volume, it is recommended to use Basic Disks or Storage Spaces. In this article, we will show you how to convert dynamic disk to basic disk on Windows 11 How to convert dynamic disk to basic disk in Windows 11? In the beginning

When creating a virtual machine, you will be asked to select a disk type, you can select fixed disk or dynamic disk. What if you choose fixed disks and later realize you need dynamic disks, or vice versa? Good! You can convert one to the other. In this post, we will see how to convert VirtualBox fixed disk to dynamic disk and vice versa. A dynamic disk is a virtual hard disk that initially has a small size and grows in size as you store data in the virtual machine. Dynamic disks are very efficient at saving storage space because they only take up as much host storage space as needed. However, as disk capacity expands, your computer's performance may be slightly affected. Fixed disks and dynamic disks are commonly used in virtual machines

RAID or Redundant Array of Independent Disks is a data storage technology in which multiple external drives are combined into one. It was widely used when large hard drives were expensive, but many people still prefer the RAID external drive method. There are several levels of RAID, each serving a specific purpose. Keep in mind that the average user doesn't have to delve into the complexity, a simple setup of RAID0 or RAID1 should work fine. Reasons to consider raiding an external drive: Improved PC performance Easy to configure, cheaper than existing alternatives Faster data reading and writing Efficient backup solution through mirroring How to RAID an external drive on Windows 11? Before RAID external hard drives, you need to pay attention to the following first things
