I have a Hyper-V/Windows 2012 Server where I have a virtual machine with SBS2011 OS.
I have a 2TB external hard drive to backup Hyper-V server. Please see the screenshot above. Then I purchased additional 2TB external hard drive to backup SBS2011 OS and its files separately and attached it to DC1 (name of VM). But I like to disconnect (or remove) it from the DC1 VM because it seems to be failing.
What are the steps to follow to remove it from the VM and HyperV completely?
