The VMDK file format is pretty well documented: https://www.vmware.com/support/developer/vddk/vmdk_50_technote.pdf

Interesting tidit: There are oer 10 different VMDK subformats (some of which are identical, but some are quite special...)

I know, that's why I'm doing other disk image formats first ;)

Now I need to get compressed, encrypted, vmfs and streamoptimized images for testing.

I can get you some ESX images (thin, eager thick, lazy thick and RDM) if that's what you mean by "VMFS". StreamOptimized are probably inside OVF templates (I will take a look). I have not yet encountered compressed images but encrypted images can be created by VMware workstation.

I'll see what I can find

Edit:
VMFS type vmdk from ESX server
Encrypted VMDK (it's actually the complete VM, but the VMDK is probably not what you're looking for. The key for decryption is "qwe123")
StreamOptimized type vmdk (this is actually a complete OVA that contains 2 different vmdks)

Ok I'll try them asap.

I've read on the documentation that the disk descriptor can indicate if the vmdk is encrypted.
We'll see.

But encryption will nonetheless not be implemented until compression is, at least Iwant to detect and fail gracefully.

Edit:
VMFS OK.
OVA contains compressed extents, fails gracefully.
The encrypted one is empty, can you populate it with FreeDOS?
