Command: shsufdrv
  SHSUFDRV simulates a floppy or hard disk using an image file.
Syntax:
  SHSUFDRV [/F[:][?]]image[,drive]... [/W] [/V] [/U] [/Q[Q]]
           /F:    The path to the image.
           image  Filename of raw disk image; '?' will ignore an invalid
                  image.
           drive  Drive letter to use (default is first available).
Options:
  /W      Allow images to be written.
  /V      Display memory usage (only at install).
  /U      Unload.
  /Q      Quiet - don't display sign-on banner.
  /QQ     Really quiet - don't display anything.
Comments:
  Image files can be created with DISKCOPY.
  No drive letter will be assigned lower than the first.
  Eg: img1,E img2,D will assign to E: and F:, *not* E: and D:.
  Only the drive (on the first partition of a hard disk) is simulated,
  not the disk itself, and only a 512-byte sector size.
  SHSUFDRV / SHSURDRV has the following EXITCODES (ERRORLEVEL):
    0     Uninstalled, help displayed
    1-32  First drive letter assigned (A: = 1) on successful install;
    255   Not installed, not uninstalled
