Drive map for Virtual Machine

Hi,

I installed Defraggler on a VM that was "thin provisioned" and it told me the defrag of that drive would be slow because there was less than 10% real free space. So I stopped the defrag and changed the disk to "Thick Provisioned" and when I started Defraggler the message was, of course, not displayed.

However the map of the drive remained the same and the real free spece was not displayed. Can that be corrected somehow?

Thanks,

NB
