Before attempting recovery, it is vital to understand the root cause to prevent recurrence. Common scenarios include: When a partition disappears, the data is often

This is an advanced procedure. Do not attempt this if you are not comfortable with the command line or have already written new data to the disk.

The loss of a VMFS datastore is a critical event that can halt production and risk significant data loss. Unlike standard file systems (NTFS, EXT4), VMFS is a clustered file system specifically designed by VMware for virtual machine storage. Recovery requires a precise understanding of the partition table structure and the location of the VMFS superblock. This document outlines the methodology for diagnosing lost partitions and executing recovery operations using both native ESXi tools and third-party utilities, with a strong emphasis on risk mitigation.
