OPTIONS

       -info input.chd
              Dump the header information from a drive image.

       -createraw inputhd.raw output.chd [inputoffs [hunksize]]
              Create a new compressed raw image from a raw file.

       -createhd  inputhd.raw  output.chd  [inputoffs  [cylinders   heads   sectors   [sectorsize
       [hunksize]]]]
              Create a new compressed hard disk image from a raw file.

       -createblankhd output.chd cylinders heads sectors [sectorsize [hunksize]]
              Create a new non-compressed hard disk image, with all hunks filled with 0s.

       -createcd input.toc output.chd
              Create a new compressed CD image from a raw file.

       -copydata input.chd output.chd

              match.  If the source is shorter than the destination,  the  source  data  will  be
              padded with 0s.

       -extract input.chd output.raw

       -extractcd input.chd output.toc output.bin

       -verify input.chd
              Validate the MD5/SHA1 on a drive image.

       -verifyfix input.chd
              Validate and fix the MD5/SHA1 on a drive image.

       -update input.chd output.chd
              Update CHD image using metadata from input file.

       -chomp input.chd output.chd maxhunk
              Chomp hunk from CHD image.

       -merge parent.chd diff.chd output.chd
              Merge a parent and its child together.

       -diff parent.chd compare.chd diff.chd
              Generate a difference between two CHD files.

       -setchs inout.chd cylinders heads sections
              Change the CHS values on a hard disk image.

       -split input.chd output.chd length
              Split a CHD file into multiple parts.
