Vmfs Partition Table Recovery

Understanding why a partition table fails can help determine the correct recovery path.

Provided the underlying blocks have not been overwritten, the redundant nature of VMFS metadata makes recovery highly probable if the correct tools are used.

When that partition table gets corrupted or deleted, ESXi sees the raw disk as a blank, unpartitioned device. However, the actual VMFS filesystem metadata (heartbeats, file descriptors, block pointers) lives inside the partition, untouched. vmfs partition table recovery
