Recovering a VMFS 5 datastore is possible in most logical corruption scenarios. Native tools like voma and partedUtil can repair partition tables and minor metadata errors. For severe corruption (e.g., overwritten file descriptors), third-party recovery tools are recommended. The most critical factor is to prevent overwriting recoverable data.

If resignature succeeds, the datastore reappears with a new UUID.

Locate backup VMFS boot sector (often at sector 256, 512, etc. using hex dump). Native tools like voma and partedUtil can repair
