If the above methods are not feasible, you might need to manually reconstruct the VMDK descriptor file. This involves creating a new text file with the necessary metadata: restore vmdk descriptor file

If you have a valid descriptor file for a different disk (or a backup of the VM’s configuration), you can try to recreate it automatically.

Restoring a VMDK descriptor file can be a straightforward process using VMware tools. It's essential to have backups of critical VM files, including the VMDK descriptor file, to prevent data loss in case of corruption or deletion. Always take a checksum (MD5) of the -flat

If the map is missing, ESXi can’t find the cargo. Here is how to draw a new map.
