Hello everybody:

I have some VHD that are very big over 300Gb and i don't need VHD so big. I want reduce the size of this VHD, they are Fixed size.

I was thinking to create a new VHD with teh correct size and clone over it the big VHD.

But may be there is another easy way to do the "resize"

Any idea?

    Your plan is probably the safest way to go. You can also just convert to dynamic and then do a disk compaction, but you disk can grow again. There is very little performance difference between dynamic and fixed VHD under Hyper-V R2. All my VHDs are dynamic.

    Shut down the VM, and then edit disk using the Hyper-V Console.
