My client is running a PHYSICAL server with Windows 2008. We are running Hyper-V with SBS-2003 as a VIRTUAL system. We have 2 separate external USB hard drives physically attached to the server. For clarity I will call them the "M" and "P" drives. I have shared only the "P" drive and mapped it inside the virtual SBS2003 system.
My problem is I cannot "stop" either of them using the "safely remove hardware" icon. I have tried to stop them from both the Windows 2008 and the virtual SBS-2003 side. No luck
The error message says, "Windows cannot stop your 'generic volume' device because it is in use"
I can kinda understand not being able to stop the mapped "P" drive if the virtual machine is running (although that still is a bummer), but I cannot stop the UNMAPPED "M" drive.
Best I can tell, there is nothing "using" the "M" drive but it will not unmount.
