Summary: To address the “Virtual Disk is not accessible on the host” error prevalent in VMware, we explored its causes and presented a reliable solution – the Kernel VMDK Recovery tool. This tool simplifies recovery and ensures data accessibility, offering a seamless experience for virtual machine management.

We have noticed an increasing number of inquiries regarding the error message, “Virtual Disk is not accessible on the host.” To address this issue comprehensively, we have decided to delve into this topic and offer viable solutions.

This error is most prevalent in the VMware environment. The error message is “Virtual disk is not accessible on the host, unable to access the file.”

When users encounter the “Virtual Disk is not accessible on the host” error, they often find themselves unable to access their VMDK (Virtual Machine Disk) files, leading to frustration and inconvenience. To shed more light on this issue, let’s delve into the error’s potential causes and gain a deeper understanding of its origins.

Some General Information

Creating a Virtual Machine using VMware Workstation typically involves a straightforward process, starting with the “New Virtual Machine” option. Once the virtual machine is up and running, and you’ve completed the Windows installation, you may choose to install VMware Tools to enhance its functionality. This Virtual Machine, at its core, relies on VMDK files, which are stored on the host computer’s hard disk. VMware exclusively utilizes the VMDK file format for its digital data storage.

However, the issue arises when attempting to access the virtual disk. Users may encounter the error message, “Virtual disk is not accessible on the host, unable to access the file,” which effectively restricts access to the virtual disk and the data contained within it. This error can be frustrating and disrupt the smooth operation of the virtual machine.

Some Possible Causes Behind the Error

Go through some of the most common causes to the “Virtual disk is not accessible…” error.

  • Inefficient disk management
  • Forceful/sudden system shutdown or termination of VMDK files
  • Cleared system registry
  • Hardware issues
  • Corruption of VMDK files

These errors can ultimately affect the Virtual Database files and make then corrupt, further making the data inaccessible.


We advise you to check the disk space on your system first and the space allotted for Virtual Machine. Also, increase the storage space on it and then try to access the virtual disk again.

Next, you can check the hardware connected to the system. If there is an issue, rectify it then and there.

For corrupted VMDK files, we suggest you try a manual solution. Just try performing these steps on your host system.

  1. Press the Windows key and R letter together and type cmd in it to open the Command Prompt.
  2. Now, follow the path C: ->program files->VMware->Virtual disk Development kit ->bin, which is the local installation of the VMware development Kit.
  3. Next in the Command Line tool (Command Prompt), run the command “VMware-vsdiskmanager ”-R
  4. This could repair your VMDK files to an extent which you can check by starting your Virtual Machine and access data on the VMDK file.

Though you can give the above method a chance, you should not completely rely on the above-explained manual method as there is no such guarantee of file repair.
