I am working on a vmdk decoder for various disk types. Need to create vmdk disks to test the decoder. But there are a few types I wasn't able to create with any tool:
vmfsEagerZeroedThick
vmfsPreallocated
vmfsRaw
vmfsRDM
vmfsRDMP
vmfsSparse
vmfsThin
fullDevice
partitionedDevice
The types are on the official "virtual disk format 5.0" https://www.vmware.com/support/developer/vddk/vmdk_50_technote.pdf
I used vmkfstools to create "vmfs" (in descriptor file createType="vmfs"). it is not on the above document.
