Sysinternal ha appena rilasciato questo fantastico tool, che permette di convertire un volume in un file .vhd anche durante il suo funzionamento
“Disk2vhd is a utility that creates VHD (Virtual Hard Disk - Microsoft’s Virtual Machine disk format) versions of physical disks for use in Microsoft Virtual PC or Microsoft Hyper-V virtual machines (VMs). The difference between Disk2vhd and other physical-to-virtual tools is that you can run Disk2vhd on a system that’s online.”
