Mount Vmfs 6 Windows Hot [hot] May 2026
Mounting a partition directly in a Windows environment is not natively supported, as VMFS is a proprietary file system designed for VMware ESXi. While older versions like VMFS 3 could be accessed with legacy drivers, modern VMFS 6 requires specialized third-party tools or a Linux-based bridge for access. Summary of Access Methods Third-Party Recovery Software
: The most direct way to read VMFS 6 in Windows is through specialized software such as DiskInternals VMFS Recovery tools, which can scan the disk and allow file extraction. Linux Bridge (WSL or VM)
: Using a Linux environment (like Ubuntu via WSL2 or a VM) allows you to use vmfs6-tools
. This tool enables mounting the volume in a read-only mode using FUSE. ESXi Host (Native Method)
: The safest method is connecting the storage to an ESXi host, which natively supports VMFS 6, and accessing files through the Datastore Browser Implementation Guide: Mounting via Linux-Bridge mount vmfs 6 windows hot
For users needing a "hot" mount without a dedicated ESXi host, the vmfs6-tools utility is the standard open-source approach. Prepare the Environment
: Install a Linux distribution (e.g., Ubuntu 20.04 or later). Install VMFS6-Tools : Download and install the package:
wget http://http.us.debian.org/debian/pool/main/v/vmfs6-tools/vmfs6-tools_0.1.0- _amd64.deb dpkg -i vmfs6-tools_0.1.0- _amd64.deb Use code with caution. Copied to clipboard Mount the Volume : Identify the partition (e.g., ) and mount it to a local directory: vmfs6-fuse /dev/sdc1 /mnt/vmfs6 Use code with caution. Copied to clipboard Access Data : The files will now be visible in /mnt/vmfs6

How to Mount VMFS 6 on Windows: The "Hot" Guide to Accessing VMware Data
If you’ve found yourself searching for "mount VMFS 6 windows hot," you are likely in one of two stressful situations: either you’re trying to perform a live migration, or (more likely) a VMware host has failed, and you need to pull critical data off a VMFS LUN immediately using a Windows machine.
There is a common misconception that you can simply plug a VMFS drive into a Windows PC and read it like an NTFS or FAT32 drive. Windows does not natively understand the VMFS (Virtual Machine File System) file system. If you try to open the disk in Disk Management, Windows will prompt you to "Initialize" it, which is a trap—doing so will destroy your data.
Here is how to safely access VMFS 6 data on Windows, along with the tools you need to get the job done.
4. UFS Explorer Professional (Paid, Forensic-Grade)
The most robust commercial solution. UFS Explorer can mount VMFS 6 in read-write mode if you disable ESXi access first, but for hot mounting, you use “Read-Only Access” mode. It also handles complex RAID configurations. No ESXi host is actively using the LUN
Conditions for Safe Read-Write Hot Mount:
- No ESXi host is actively using the LUN. You must remove the datastore from vSphere while keeping the SAN LUN presented.
- Disable ATS (Atomic Test & Set) – VMware’s locking mechanism. Without this, ESXi will reclaim the lock mid-operation.
- Use a tool like UFS Explorer RW – Only UFS Explorer Professional and Runtime’s GetDataBack support writing to VMFS 6.
Why This Is "Hot":
- The driver is loaded into the kernel on-the-fly.
- You can unmount via the same tool without restarting.
- Supports VMFS 6 (including 512e and 4Kn drives).
Step-by-Step Hot Mount Process:
- Download StarWind V2V Converter (free version) from their official site.
- Install it – No reboot required during installation.
- Connect your VMFS 6 disk to Windows via USB enclosure, direct SATA, or iSCSI.
- Open Device Manager →
Disk Management. Verify the disk appears asUnknownorGPT Protective Partition. Note the Disk Number (e.g., Disk 3). - Launch StarWind V2V Converter.
- Select "Local File" as the source (counterintuitive, but works).
- In the file browser, look at the bottom left – there is a "Mount VMFS" button.
- Click it, select your Disk Number, and choose a drive letter (e.g., Z:).
- The tool loads a temporary driver – no reboot. You now have read-only access to the VMFS 6 datastore.
Result: You can browse all VM folders, copy .vmdk, .vmx, and .vswp files to a healthy NTFS drive.
Introduction: The Cold Reality of VMFS Access
If you are a VMware administrator, you have faced this nightmare: An ESXi host fails. A virtual machine (VM) won’t power on. Your backup is corrupted. The only hope is to pull a physical disk from the server, attach it to a Windows machine, and copy the VMDK files directly.
But here is the catch: Windows cannot natively read VMFS 6 (the file system used by ESXi 6.5, 6.7, 7.0, and 8.0).
Traditional solutions require installing third-party drivers that demand a restart (cold mount). In a disaster recovery scenario, rebooting a production Windows server is unacceptable. You need a "hot" mount – attaching and reading the VMFS 6 volume without shutting down or restarting your Windows system.
This article provides a step-by-step guide to hot mounting VMFS 6 on Windows using modern software tools, command-line tricks, and forensic techniques.
Part 2: Prerequisites – Can Windows Natively Mount VMFS 6?
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.
