Mount Vmfs 6 Windows Hot

Best for: IT forensics, no commercial software allowed.

A community-maintained project, vmfs6-tools, can be compiled for Windows using the Windows Driver Kit (WDK). This method does not require a pre-installed driver.

In the world of enterprise virtualization, VMware’s VMFS (Virtual Machine File System) is the gold standard for storing virtual disks, snapshots, and configuration files. With the introduction of VMFS 6 (released alongside vSphere 6.5 and later), VMware brought improvements like automatic space reclamation and support for larger block sizes. However, one persistent challenge remains for Windows administrators: How do you mount a VMFS 6 volume directly on a Windows machine, ideally in a ‘hot’ (online, read/write) state?

If you’ve typed “mount vmfs 6 windows hot” into a search engine, you’re likely looking for a solution that avoids shutting down your ESXi host or copying massive VMDK files over the network. Let’s break down the reality, the available tools, and the limitations.

Yes, it’s a converter. But it has a hidden superpower: it can mount a VMFS 6 volume as a Windows drive letter.

Step-by-step (no fluff):

Hot Tip:
Once mounted, use 7-Zip or DiskInternals VMFS Recovery if StarWind fails on heavily corrupted volumes. But for 95% of cases, the free method works.

What About Write Access?
Don’t. Seriously. VMFS 6 has advanced locking and heap structures. Writing from Windows will corrupt the datastore 99% of the time. Mount as read-only, copy your VMDKs to NTFS, then do what you want. mount vmfs 6 windows hot

Alternative – The Geek Way (No Extra Software)
If you’re on Windows Server, you can install Linux subsystem (WSL2) and use vmfs-tools (after compiling). But that’s a 2-hour journey. The hot method above takes 2 minutes.

Bottom Line
Yes, you can mount VMFS 6 on Windows. No, you don’t need a full ESXi host. Use StarWind’s free tool as a read-only bridge, grab your files, and get back to fixing your homelab or production environment.

Have you tried mounting VMFS 6 on Windows another way? Drop a comment below. And remember: always back up before attempting mounts on production disks.

Windows does not natively support the VMFS 6 file system. While legacy tools like the "Open Source VMFS Driver" work for VMFS 3, they are incompatible with VMFS 6. To access VMFS 6 data on a Windows machine, you must use a Linux-based bridge or professional recovery software. Method 1: Using WSL2 (Recommended Free Method)

You can use the Windows Subsystem for Linux (WSL2) to mount the physical drive and use Linux-native vmfs6-tools to read the data.

Set Drive Offline: Open Disk Management (diskmgmt.msc), find your VMFS disk, right-click it, and select Offline so Windows doesn't lock it.

Identify Disk Number: Open PowerShell as Administrator and run:Get-CimInstance -Query "SELECT * from Win32_DiskDrive"Note the DeviceID (e.g., \\.\PHYSICALDRIVE1). Best for: IT forensics, no commercial software allowed

Mount in WSL: Run the following in PowerShell to attach the drive to WSL:wsl --mount \\.\PHYSICALDRIVE1 --bare.

Install Tools in WSL: Open your WSL terminal (e.g., Ubuntu) and install the driver:sudo apt update && sudo apt install vmfs6-tools. Mount the File System: Find the partition: lsblk.

Mount it: sudo vmfs6-fuse /dev/sdX1 /mnt/vmfs (where sdX1 is your VMFS partition). Method 2: Professional Recovery Software

If you prefer a GUI-based Windows application, third-party recovery tools can scan VMFS 6 partitions and extract files. Note that most of these require a paid license for full data extraction.

DiskInternals VMFS Recovery: Supports VMFS 6 and can reconstruct VMDK files even from corrupted RAID arrays.

Hetman Partition Recovery: Uses an NTFS scan option to identify files within VMFS partitions if the host server is damaged. Method 3: Secondary ESXi Host (Safest for Data)

The most reliable way to access a "hot" or existing VMFS 6 datastore is to connect it to a healthy ESXi host. Attach the disk to a server running ESXi 6.7 or newer. Hot Tip: Once mounted, use 7-Zip or DiskInternals

In the vSphere Web Client, go to Storage > Devices and click Rescan. Right-click the detected volume and select Mount.

Use the Datastore Browser to copy files or register the VMs.

Note on "Hot" Mounting: If the disk was part of an active RAID or is currently being accessed by another host, ensure you mount it as Read-Only (standard for third-party tools) to prevent data corruption.

Here’s a technical write-up based on the search query “mount vmfs 6 windows hot” — which suggests a need to mount VMware’s VMFS 6 datastores on a Windows system, likely “hot” (i.e., without shutting down the ESXi host or rebooting Windows).

Short answer: No. Windows does not include a native driver for VMFS 6. Disk Management will recognize the physical disk but show it as “Unknown” or “RAW.” To mount VMFS 6 on Windows hot, you need third-party software.

Best for: Live hot mount without reboot. Free tool.

StarWind V2V Converter includes a hidden gem: a VMFS 6 reader that dynamically loads a driver on demand.
