In cases of severe corruption, professional recovery tools may be required to scan the raw disk for VMFS headers and reconstruct the file hierarchy. Best Practices and Prevention

If a volume is detected as a snapshot (often after a hardware change), it may need to be "resignatured" to be mounted. This assigns a new UUID to the volume, allowing the ESXi host to recognize it as a unique datastore. Step 3: Manual Partition Table Recovery vmware repair vmfs partition
