vmkfstools -x repair /vmfs/volumes/datastore1/VM/VM-flat.vmdk If repair fails, clone the VMDK while forcing consistency checks:
Create a new .vmdk descriptor pointing to the raw data file: recover data from corrupt vmdk
7z l corrupt.vmdk # list contents 7z x corrupt.vmdk -orecovery # extract all files Limitation: Only works for simple VMDK formats (not split/extents). vmkfstools -x repair /vmfs/volumes/datastore1/VM/VM-flat
