	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 multiple data tracks that are not in the same MODE.
  
  - 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.

WARNING: Do not attempt to use SNAPSHOT/DAO to make CDROM-XA discs
on the CDD2000, 4020i, CDR4220, or CDR100IPW recorders with version
1.20 firmware. These recorders have a disc-at-once firmware bug that
cause them to write improper CDROM-XA discs. This problem has been
fixed in version 1.25.

WARNING: The Pinnacle/JVC recorders cannot read or write RAW data
sectors. Because of this limitation, you must always use the /COOKED
option when reading data discs (both MODE1 and MODE2).

WARNING: All Toshiba 3501 drives made before January 1995 have a
firmware bug that causes them to improperly read audio tracks.
This problem can usually be worked around by turning off "jitter
correction". However, you will probably not get 100% exact copies
of the audio data if you do this.

>>> COMMAND LINE USAGE <<<

Usage: SNAPSHOT <cuefile> [imagefile] [/ID=ha:id:lun] [/BATCH] [/BEEP]
         [/CDG] [/COOKED] [/ISRC] [/JC] [/NOJC] [/NOCONFIRM] [/SPEED=n]
         [/SUBCODE=option] [/THRESH]
cuefile    - Output cue sheet filename
imagefile  - Output image filename (optional)
/ID        - SCSI 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
/COOKED    - Read cooked data (default is raw sectors)
/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)


CUEFILE - The CUE SHEET for the disc is automatically generated and
written to this output file.

IMAGEFILE - The entire contents of the disc (both data and audio tracks)
are written to this output file. NOTE: If this file is not specified,
then only the cuesheet will be generated.

/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.

/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.

/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).

/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.

/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.

Here are my recommendations on when to use the /COOKED option depending
on what type of disc is being copied and what CD recorder is going to be
used to write the new disc...
	    
	   USE /COOKED?
  MODEL    MODE1  MODE2
|-----------------------|
| HP        No     No   |
|-----------------------|
| JVC       Yes    Yes  |
|-----------------------|
| OLYMPUS   Yes    *    |
|-----------------------|
| PHILIPS   No     No   |
|-----------------------|
| PINNACLE  Yes    +    |
|-----------------------|
| RICOH     No     No   |
|-----------------------|
| SONY      Yes    *    |
|-----------------------|
| TEAC      Yes    No   |
|-----------------------|
| YAMAHA    Yes    *    |
|-----------------------|

* = Your choice!

+ = Pinnacle RCD5040 - Yes
    Pinnacle RCD4X4  - No

WARNING: You must use a transfer setting of 2352 when reading any
data disc that is to be recorded on an HP, Philips, or Ricoh recorder.
These models do not support the writing of cooked data sectors in
disc-at-once recording mode.

WARNING: You must use a transfer setting of 2352 when reading any
mixed mode disc (both data and audio) that is to be recorded on the
Teac CD-R50S, Pinnacle RCD4x4, JVC XR-W2020, or S&F 2006PLUS. These
models do not support writing tracks with different block lengths in
disc-at-once recording mode.

WARNING: You must use a transfer setting of 2048 (Mode1) or 2336 (Mode2)
when reading any data disc that is to be recorded on the Pinnacle RCD5040
or JVC XR-W2010. These models do not support the writing of raw data
sectors in disc-at-once recording mode.

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

>>> READING KARAOKE CD+G DISCS <<<

To backup KARAOKE CD+G discs, you must have a Yamaha, Panasonic 7501,
or Sony CDW-900E recorder. These are the only recorders that will write
the R-W subcodes required for CD+G discs. You must also have another
CDROM device that can *read* the R-W subcodes as these recorders can
only write these subcodes.

The following CDROM drives can read CD+G discs...

  PLEXTOR 4Plex Plus
  PLEXTOR 8Plex
  PLEXTOR 12Plex
  PLEXTOR 12/20Plex
  PLEXTOR 14/32Plex
  SONY 76S
  SONY CDU415
  SONY CDU920S

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

>>> HELPFUL HINTS <<<

1) When using SNAPSHOT on the JVC XR-W2010 or Pinnacle RCD-5040,
   you must do the following!!

   - After SNAPSHOT analyzes the disc, it will prompt you to hit
     return to start copying. Before you do this, eject the disc
     from the recorder and reload it. If you do not do this, the
     drive will read the data track incorrectly.

2) When copying any disc that has audio tracks (especially PlayStation)
   always use the /SUBCODE=AUTO or /SUBCODE=SOME option. If you don't,
   then the audio tracks on some game discs may not play properly.

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

>>> 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).

  WARNING: The output files could require as much as 750Mb of disk space.

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

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