How to extend a VM’s Hard Disk on VMware Workstation

maxresdefault

A virtual disk is a file (or a set of files) on the host system that appears as a physical disk drive to the guest operating system. Virtual hard disk files store information such as the operating system, program files, and data files and have a .vmdk extension. Virtual disks can be stored as files on the host computer or on a network file server. It does not matter whether the physical disk that holds the files is IDE or SCSI. A virtual IDE drive can be stored on an IDE drive or on a SCSI drive. Kindly refer to these related articles: ESXI 6.7 ALARM: Seat disk exhaustion on 10, how to convert a GPT disk into an MBR disk error: Windows cannot be installed on drive 0 Partition 1, how to clone a server on VirtualBox, the virtual machine ran into a non-fatal problem as described below, we suggest that you take appropriate action to prevent the problem from recurring, how to solve VMware workstation .lck error, and the VM appears to be in use, how to create a VM (virtual machine) on VMware.

If you have a snapshot created for this specific VM you wis to extend, you will never be able to expand your hard disk. You need to delete the snapshot first. To do this, please visit this link. You may want to see how to add and remove a new virtual disk from a VM on VMware Workstation.

In order to extend your VM Hard Disk, you will have to stop the Vm and edit the virtual machine settings as shown below.

This will open the Expand Disk Capacity wizard. As you can see, the current size is 80GB and I wish to add 20 GB more.

As you can see from the image below, we have 20GB f unallocated space. We will have to extend the C drive (existing partition) with this space.

Right-click on the Disk Drive and select Extend

I will be allocating the entire space, therefore, I will just click on Next.

The space has been allocated. I will click on Finish to complete this process.

As you can see, the previously unallocated space has been utilised by the existing partition.
