How to Recover VMware ESXi 6.7 Virtual Machine Data from VMFS 5 and VMFS 6 Storage

Loss of access to virtual machines in VMware ESXi 6.7 may be caused by datastore corruption, accidental file deletion, drive failures, or hypervisor configuration errors. If the virtual machines were stored on VMFS 5 or VMFS 6 datastores, information recovery requires consideration of the structure of these file systems and the location of virtual disk files. In this article, we will examine how to access lost data, recover virtual machine files, and restore important information even in cases where standard VMware ESXi tools no longer provide access to the datastore.
