File Disk
This little tool by Bo Brantén allows the mounting of a disk image to a drive letter. It works on WinNT/2000/XP/Vista/7. It can be found here
Usage
Mounting a image: Filedisk requires windows style full path of the image to mount the image. If a relative path or unix style path are given, it will fail. Note: Inside cygwin, Unix style path name can be converted to Windows absolute path name using the command cygpath
filedisk /mount 0 "C:\Full\Path\To\Image\disk.img" m: filedisk /mount 0 `cygpath -a -w Image/disk.img` m:
Unmounting a image:
filedisk /umount m:
