Vmdk created with ESX (or ESXi)

Hey,

when I want to retrieve info about a vmdk, which was created by ESX, with volinfo.exe, I get an Exception.

Output of such a call:

K:\Tools\DiscUtils>VolInfo.exe d:\temp\XP-flat.vmdk

Is it known that Vmdks created with ESX don't work?

Ok ,... I was to fast :) ... when I try to open the flat file directly the exception occurs, but when I use it via the Disk DescriptorFile vmdk thing, then it works.

Does every Flat vmdk has such a Disk DescriptorFile ? Or vmdk in general?
