He opened an SSH session to the host and ran the vmkfstools and esxcli commands he’d practiced in quieter times. The output showed the VMFS-6 signature present but not mounted. A careful probe confirmed the host hadn’t claimed the volume exclusively—good news. That meant he could mount the volume read-only to inspect without risking writes. He mounted it, like easing open that locked warehouse door and stepping inside with flashlight in hand.
Choose the physical disk number corresponding to your VMFS 6 drive (verify this number via Windows Disk Management, e.g., PhysicalDrive1). Select . Step 3: Mount the Volume inside the Guest Environment
The most robust commercial solution. UFS Explorer can mount VMFS 6 in if you disable ESXi access first, but for hot mounting, you use “Read-Only Access” mode. It also handles complex RAID configurations.

In the context of VMware and data recovery, "hot" carries a crucial, specific meaning. It generally refers to . This is most relevant when using a "Hot Add" backup method and is a primary reason users search for this term.
Ensure your Windows machine can see the storage block device. This could mean mapping the iSCSI target using the Windows iSCSI Initiator or zoning your Fibre Channel SAN to the Windows host.
VMFS 6 is a highly optimized, cluster file system designed by VMware for ESXi hosts. It features advanced metadata structures, automatic space reclamation (UNMAP), and support for 4K native storage sectors. mount vmfs 6 windows hot

The software automatically scans all attached physical drives and network LUNs. It will detect the VMFS 6 signature even if Windows labels the drive as RAW.
VMFS 6 uses sub-blocks and thin provisioning. Ensure your tool is updated for VMFS 6 (not just VMFS 5). Older tools will show an empty folder. He opened an SSH session to the host
If your VMFS 6 volume was part of a hardware RAID array, you cannot simply connect one drive to a Windows PC. You must connect the entire array to a compatible RAID controller on the Windows machine first.
