I have 4TB HD(effective space: 3,695 GB) and I had assigned 2TB to my Windows 7 VM.
I wanted to increase it, so I entered 3.695 in VM/Edit/Hard Disk screen and it worked (even thought I have not gone to Computer Management in Windows 7 to expand the partition yet)
The I realized that I should have left some space in the datastore to create additional VMs down the road, so I went back to Windows 7 VM to reduce the size to 3TB. But it won't change.
I thought you could resize the VM disk anytime.
Can you help?
