Disk2VHD

     Mark Rossinovich and Bryce Cogswell at sysinternals have created all kinds of great free utilities over the years. Disk2vhd has to be one of my favorites. I have used it to virtualize my old XP machine to use on Windows 7 and used it to virtualize SBS 2003 servers to do complete off site swing migrations. But just like any other tool there are limitations and times that it doesn't work as planned.

   If you have disk or array issues on the machine you are using it on, chances are that it will fail to work at all or end up giving you a corrupted VHD. I recently created a VHD from a machine that was giving me array errors in event viewer. If I mounted the VHD with 2008 disk manager, the primary partition showed up as RAW. After searching posts I found a utility called testdisk http://www.cgsecurity.org/wiki/TestDisk. Another great free tool to have in your kit. I used it to fix the disk configuration and was then able to boot the VHD.
