Hello,

I've created a new dedup volume and mounted with these commands:

mksdfs --volume-name=vms --volume-capacity=10000GB --base-path=R:\VMs --chunk-store-hashdb-location=C:\DedupHashDB\VMs
mountsdfs -v vms -m v

I can create a new Hyper-V machine using the C: or R: drives directly just fine. 

However, if I use the V: (The Deduped volume) I get the following error:

I'm running Windows 10 (Build  18363) and OpenDedup 3.5.7

Also, when I try to delete the empty folder that Hyper-v made to store the VM (TestVM) I get this error on the vms-volume.log
