My personal desire is make a full dd copy of a snapshot onto a external drive.
ie. dd if=/dev/sd-shadowcopy4 of=<my_image_file>
With new Cygwin 1.7, the VSS volume image can be retrieved as follows:
dd if='//?/GLOBALROOT/Device/HarddiskVolumeShadowCopy4' of=...
But this does not work with Cygwin 1.5.
To access individual files, assign a drive letter X: to the VSS volume:

Then you can access the files via /cygdrive/x. This works with cygwin
1.5 also. Only the WinXP explorer refuses to access the drive.
