Can not see the volume in Window instance

[lemon1707]

I had started a Cloud on single machine with Ubuntu 9.10 64 bit. Everything worked good, I attached a volume to window instance running, it changes the status of volume from available to in-use, but when I used RDP to login to instance,Go to Start -> Run and type diskmgmt.msc, I didn't see any new disk at the bottom of the list.
I had found everything on forum and some other but I couldn't find the problem. Please help me to solve that problem !

Disk hotplug might not be in KVM for windows guests. Please try powering off the VM, attaching disk, then starting. Also might want to try a newer Ubuntu like 11.04
