When native methods fail, use dedicated VMFS recovery software:
| Structure | Sector offset (relative to partition start) | |-----------|-----------------------------------------------| | VMFS FDC (File Descriptor) | 1-63 | | Heartbeat region 1 | 128 | | Heartbeat region 2 | 256 | | File/directory tables | 4096+ | recover vmfs 5 datastore
⚠️ Always take a backup before running fix . Major corruption may require full recovery tools. When native methods fail, use dedicated VMFS recovery
Where aa31... is the VMFS partition GUID. The end sector is total sectors minus 1 (e.g., getptbl can show max sector). When native methods fail
