Vmfs 6 Windows Hot — Mount

Limitations:

But for a quick hot extraction of a single .vmx or small log file, it works brilliantly.

| Tool | VMFS 6 Support | Hot mount allowed? | Notes | |------|----------------|--------------------|-------| | OSFMount (Passmark) | No (VMFS 5 partial) | No | Read-only for older VMFS | | StarWind V2V Converter | Yes (read-only) | Yes | Can browse/mount as virtual disk | | DiskInternals VMFS Recovery | Yes (read-only) | Yes | Forensic tool, not live r/w | | VMware Virtual Disk Dev Kit (VDDK) | Yes (read/write via SAN) | No – requires ESXi quiesce | Use over iSCSI/FC, not recommended hot | | UFS Explorer Professional | Yes (read/write) | No – must unmount from ESXi | Supports RAID reconstruction |

No reliable, production-safe tool allows true “hot” read/write of the same live VMFS 6 volume from Windows.

First, a clarification on the word "hot." In VMware terms, "Hot Add" or "Hot Extend" refers to adding storage while the VM is running. However, if you are connecting a VMFS drive to a Windows OS, that Windows OS treats it as a foreign device. mount vmfs 6 windows hot

There is currently no native driver provided by Microsoft or VMware to mount VMFS 6 as a readable drive letter (like E:\) inside Windows.

To access the data, you need third-party tools that act as a "bridge," reading the VMFS structure and extracting the files.

Do NOT initialize, format, or convert the disk when Windows prompts you. Cancel any "You need to format the disk" messages immediately.
