For most Windows users, the Linux VM method is safest and most reliable. Direct Windows tools have limited support for VMFS 5 and risk corruption.
| Tool Name | Type | Access Mode | Best For | | :--- | :--- | :--- | :--- | | | Commercial | Read/Write | Full mounting, disaster recovery, VMDK repair. | | UFS Explorer Professional Recovery | Commercial | Read/Write | Complex RAID/VMFS recovery scenarios. | | VMFS Recovery Tool (vSphere) | Official (CLI) | Read-Only | Off-line datastore mounting (usually requires Linux/ESXi, not Windows GUI). |
Before attempting to mount a VMFS5 volume on Windows, the following conditions must be met: mount vmfs 5 windows
sudo vmfs-fuse /dev/sdb1 /mnt/vmfs -o ro
vmfstool.exe -l
1. Remove datastore from all ESXi hosts ↓ 2. Connect disk to Windows machine ↓ 3. Mount as READ-ONLY using VMFS Tool ↓ 4. Copy needed files to NTFS drive ↓ 5. Unmount and disconnect ↓ 6. Reconnect disk to ESXi hosts
| Issue | Solution | |-------|----------| | "Access denied" | Run as Administrator | | Drive not appearing | Check physical connection to disk | | Corrupted files | Use Linux VM method instead | | Can't find partition | VMFS5 may have partition table; try different partition numbers | For most Windows users, the Linux VM method
VMFS5 is a proprietary file system. Unlike NTFS or FAT32, Microsoft Windows does not natively possess the drivers required to read or mount VMFS partitions. If a VMFS5 drive is connected to a standard Windows machine, it will appear in Disk Management as "Unknown" or "Unallocated," and the OS will prompt the user to initialize the disk.
