vmkfstools -x check /vmfs/volumes/datastore1/VM/VM-flat.vmdk

(works for single-file growable VMDK)

Create a new .vmdk descriptor pointing to the raw data file:

vmkfstools -i newheader.vmdk -d thin test.vmdk If the disk is too corrupt for mounting:

vmware-vdiskmanager -d /path/to/your.vmdk vmware-vdiskmanager -k /path/to/your.vmdk If the VMDK is not recognized as a disk but contains intact data blocks:

Replace RW 8388608 with your actual sector count (sectors = size_in_bytes / 512).

7z l corrupt.vmdk # list contents 7z x corrupt.vmdk -orecovery # extract all files Limitation: Only works for simple VMDK formats (not split/extents).
