  This article describes how to use dd in Cygwin on Windows.

Create an image of a disk
-------------------------

  First, find the path to the drive that you want to create an image of. Execute

    $ cat /proc/partitions

    major minor  #blocks  name   win-mounts
    
        8     0 244198584 sda
        8     1 243708577 sda1   C:\
        8     2    486400 sda2
        8    16 312571224 sdb
        8    17     56196 sdb1
        8    18 312513536 sdb2   D:\
        8    32  62367744 sdc
        8    33  62366720 sdc1   E:\
    
  Let's assume we want to image sdc. Start the Cygwin terminal with
  administrator. Execute

    # dd if=/dev/sdc of=sdc.img bs=64k conv=noerror,sync
