	SNAPSHOT.EXE - Multipurpose CDROM Backup Program


>>> PROGRAM DESCRIPTION <<<

   SNAPSHOT.EXE allows you to backup just about any CDROM disc on the
market today. This includes AUDIO, CDROM, CDROM-XA, CD-I, MIXED-MODE,
and (optionally) KARAOKE CD+G. It will also backup many game console
discs including Sony PlayStation, Sega Saturn, etc. SNAPSHOT is also
capable of generating CUE SHEET files for any disc, which can then be
used by DAO.EXE.

*************************************************************************

>>> IMPORTANT! PLEASE READ! <<<

This program is NOT freeware or shareware. If you have not purchased
and registered the fully-functional version, then you have an illegal
copy that was distributed on the Internet without permission.

SNAPSHOT will not copy...
  
  - Multisession discs.
  
  - Discs with a data track stored in the extended pregap of the first
    audio track. 
  
  - Some CD-R discs that were written with track-at-once recording.

  We do not claim that this program can copy *every* CDROM on the market.
It was not tested with every disc that you might own. Please do not call
or send Email because you have one or two discs (out of dozens or hundreds)
that will not copy. SNAPSHOT will continue to be improved in the future.

Usage: SNAPSHOT <filename> [/ID=ha:id:lun] [/BATCH] [/BEEP] [/CDG]
         [/CDTEXT] [/COOKED] [/CUEONLY] [/IGNORE] [/ISRC] [/JC] [/NOJC]
         [/NOCONFIRM] [/SPEED=n] [/SUBCODE=option] [/THRESH]
filename   - Output filename (used to name image/cuesheet/cdtext files)
/ID        - SCSI/ATAPI ID of CD reader (default is first found)
/BATCH     - Disable all messages and confirmation prompts
/BEEP      - Issue an audible 'beep' when copying has completed
/CDG       - Enable reading of CD+G discs
/CDTEXT    - Enable reading of CD-TEXT discs
/COOKED    - Read cooked data (default is raw sectors)
/CUEONLY   - Generate cuesheet file only
/IGNORE    - Ignore all reading errors
/ISRC      - Read the track ISRCs and disc MCN
/JC        - Enable audio 'jitter correction' (default is automatic)
/NOJC      - Disable audio 'jitter correction' (default is automatic)
/NOCONFIRM - Disable all confirmation prompts
/SPEED     - Audio reading speed (default is maximum)
/SUBCODE   - Subcode scanning option...
               AUTO  - Automatically select best mode for device (default)
               NONE  - Disable subcode scan
               SOME  - Scan subcode for pregaps only
               ALL   - Scan subcode for all subindexes
               FIXED - Encode a two second pregap on all audio tracks
/THRESH    - Subcode scanning threshold (default is 300 sectors)


FILENAME - This filename is used to name the DISCIMAGE, CUESHEET, and
CD-TEXT files that are created on your harddrive. For example, if the
filename "C:\TEST.BIN" is entered, then the cuesheet file will be named
"C:\TEST.CUE" and the CD-TEXT file will be named "C:\TEST.CDT".

/ID=ha:id:lun - Specifies the SCSI ID of the CDROM reader.
  "ha"  = Host adpater number (usually zero)
  "id"  = SCSI ID number
  "lun" = Logical unit number (usually zero)

/CDG - Enables the reading of CD+G audio discs. This is an optional
feature and is supported by only a few CDROM drives.

/CDTEXT - Enables the reading of CD-TEXT enhanced audio discs. This is
an optional feature and is supported by only a few CDROM drives.

/COOKED - Enables the reading of "cooked" data. When reading MODE1
and MODE2 data tracks, the block lengths will be 2048 and 2336
respectively. The default is to read "raw" sectors (2352 bytes)
for both track modes.

/CUEONLY - Generate the cuesheet file only (no image file).

/IGNORE - Ignore all errors that are encountered while reading the disc.

/ISRC - Enables the reading of the "International Standard Recording Codes"
from all audio tracks and the disc's "Media Catalog Number". This information
is not encoded on very many discs.

/JC - Enables audio "jitter correction" (SNAPSHOT automatically selects
the jitter correction mode based on the CDROM drive being used).

/NOJC - Disables audio "jitter correction" (SNAPSHOT automatically selects
the jitter correction mode based on the CDROM drive being used).

/NOCONFIRM - Disables all confirmation prompts on the screen.

/SPEED - This option can be used to change the reading speed of the
CDROM drive (not supported by all models). This can be used to slow
down very fast drives such as the Plextor 6Plex. If you experience
problems reading audio tracks, then try slowing the speed down to 1X,
2X, or 4X.
   
/SUBCODE=option - Enables the reading of audio track subcodes which
will properly duplicate all pregaps and subindexes (this feature is
not supported by all CDROM drives).

  AUTO  - Automatically selects the best scanning mode for the device.
          If the device supports the reading of subcode information,
          then the SOME option is selected. Otherwise, the FIXED
          option is selected.

  NONE  - Disables all subcode reading and pregap generation.

  SOME  - Scans the disc for pregaps only (INDEX 0).

  ALL   - Scans disc for all pregaps and subindexes (very slow!)

  FIXED - Assumes that a fixed two second pregap is present for all
          audio tracks (this option is mainly used for CDROM drives
          that don't support the reading of subcode information).


/THRESH - Used by the /SUBCODE scanning algorithm. The default value
of 300 is sufficient for 99.9% of all discs.

**********************************************************************

>>> USING THE /COOKED OPTION <<<

By default, SNAPSHOT copies raw 2352 byte data sectors (which includes
the header, user data, and error correction codes). While this can give
you an exact copy of the disc, some CDROM drives are not very good at
reading raw data sectors and errors can occur (and it takes more harddisk
space to store the raw image). In many cases it is much better to copy
just the user data, and let the CD recorder regenerate the header and
error correction codes when the new disc is written. The /COOKED option
allows you to read just the user data on both MODE1 (2048 bytes) and MODE2
discs (2336 bytes). This should greatly increase the reliability of reading
and recording all MODE1 discs. MODE2 discs are a little trickier to deal
with because they can contain two different variations of sectors called
FORM1 and FORM2.

**********************************************************************

>>> HOW TO BACKUP A DISC <<

C:\>SNAPSHOT TEST.CUE TEST.RAW /ID=ha:id:lun

  SNAPSHOT reads the original disc from the specified CDROM device
  and generates two output files... a CUE SHEET file and an IMAGE
  file. The cue sheet file describes the track layout of the disc
  and is used by DAO.EXE to rebuild the table-of-contents and subcode
  information on the new disc. The image file contains the contents
  of the entire disc (both data and audio tracks).

C:\>DAO TEST.CUE /ID=ha:id:lun

  DAO.EXE will record the new disc using the files that were generated
  by SNAPSHOT.EXE
