- 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 most of the game
- console discs including Sony PlayStation, Sega Saturn, etc.
-
- WARNING: This program is NOT freeware or shareware. If you have not
- purchased and registered the fully-functional version, then you have
- an illegal copy.
-
- NOTE: To backup a KARAOKE CD+G disc, you must have a Yamaha CDR100/102
- or Sony CDW-900E recorder. These are the only recorders that allow you
- to 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 the Yamaha
- and Sony can only write these subcodes.
-
- *************************************************************************
-
- >>> IMPORTANT! PLEASE READ! <<<
-
- SNAPSHOT will not copy...
- - Discs with more than one "data" track (rare).
- - Multisession discs.
- - Discs with the "data" track stored in an extended pregap
- of the first audio track.
-
- I do *not* claim that this program is capable of copying every
- CDROM on the market. It was not tested with every disc that you might
- own. Please do not call me or send Email because you have one or two
- discs (out of dozens or hundreds) that will not copy. I won't be able
- to help you. Any Email of this type will not be responded to.
-
- *************************************************************************
-
- >>> GAME CONSOLE DISCS <<<
-
- When backing up any game console disc (PlayStation, Saturn, 3DO, etc)
- the following information applies...
-
- !!! THIS PROGRAM WILL NOT DEFEAT THE BOOT PROTECTION SCHEME!!!
- !!! THIS PROGRAM WILL NOT DEFEAT THE BOOT PROTECTION SCHEME!!!
- !!! THIS PROGRAM WILL NOT DEFEAT THE BOOT PROTECTION SCHEME!!!
-
- Please don't send me any Email regarding the defeating of the boot
- protection. I don't know how do to it and will not offer any advice
- on this subject.
-
- *************************************************************************
-
- >>> SUPPORTED DEVICES <<<
-
- The following CDROM devices are currently supported...
-
- - Hewlett Packard 4020i
- - JVC XR-W2001, XR-W2010
- - Olympus CDS-615E (CD-R2)
- - Philips CDD522, CDD2000
- - Pinnacle RCD-1000, RCD-5020, RCD-5040
- - Plasmon CDR4220
- - Sony CDU-920S
- - Yamaha CDR100, CDR102
- - Toshiba 3401, 3501, 3601, 3701, 5301, 5401
- - Plextor 4Plex, 6Plex
-
- WARNING: Do not attempt to use SNAPSHOT/DAO to make CDROM-XA discs
- on the HP4020i or CDD2000 recorders with V1.20 firmware (this includes
- PlayStation discs). These recorders have a disc-at-once firmware bug
- that cause them to write improper CDROM-XA discs.
-
- WARNING: The Pinnacle/JVC recorders are very inconsistent at both
- reading and writing CDROM-XA discs. Therefore, I recommend that you
- don't record CDROM-XA discs on these models... sometimes they work
- and sometimes they don't. The new RCD-5040 and XR-W2010 appear to be
- more stable than previous models.
-
- 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 <datafile> <audiofile> <cuefile>
- [/ID=adapter:id:lun] [/CDG] [/COOKED] [/NJC] [/SPEED=n]
- [/SUBCODE] [/BIN] [/MOT] [/WAV]
- datafile - Output filename for DATA track
- audiofile - Output filename for AUDIO track(s)
- cuefile - Output filename for CUE SHEET
- /ID - SCSI ID of CD reader (default is first found)
- /CDG - Enable reading of CD+G disc subcodes
- /COOKED - Read cooked user data only (default is raw sectors)
- /NJC - Disable 'jitter correction' when reading audio tracks
- /SPEED=n - Audio reading speed (default is maximum)
- /SUBCODE - Scan audio subcode for pregaps
- /BIN - Write audio file in Intel binary format
- /MOT - Write audio file in Motorola binary format
- /WAV - Write audio file in WAV format (default)
-
- The /SPEED switch 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, try lowering the speed
- to 1x, 2x, or 4x.
-
- **********************************************************************
-
- >>> FORMAT OF /ID SWITCH <<<
-
- /ID=adapter:id:lun
-
- adapter - adapter number of your SCSI card (usually zero unless you
- have more than one SCSI card in your system).
- id - SCSI ID of the CDROM reader/recorder.
- lun - logical unit number (must be zero).
-
- Example: /ID=0:5:0
-
- **********************************************************************
-
- >>> 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 and MODE2 discs. 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...
-
- MODEL MODE1 MODE2
- |-----------------------|
- | HP No No |
- |-----------------------|
- | JVC Yes No |
- |-----------------------|
- | OLYMPUS Yes * |
- |-----------------------|
- | PHILIPS No No |
- |-----------------------|
- | PINNACLE Yes No |
- |-----------------------|
- | SONY Yes * |
- |-----------------------|
- | YAMAHA Yes * |
- |-----------------------|
-
- * = Your choice!
-
- NOTE: Never use /COOKED if you are using an HP or Philips recorder.
- These recorders can only write raw data sectors.

- >>> HOW TO BACKUP A DISC <<
-
- C:\>SNAPSHOT TEST.RAW TEST.WAV TEST.CUE /ID=adapter:id:lun
-
- SNAPSHOT reads the original disc from the specified SCSI device
- and generates two IMAGE files and a CUE SHEET file. The first image
- file will contain the contents of the data track, and the second
- image file will contain all of the audio tracks. You must specify
- both files even if the original disc doesn't have data/audio tracks.
-
- The CUE SHEET file describes the track layout of the disc. This file
- is used by DAO.EXE to re-generate the table-of-contents and subcode
- data on the new disc.
-
- WARNING: The output files could require as much as 750Mb of disk space.
-
- C:\>DAO TEST.CUE /ID=adapter:id:lun
-
- DAO.EXE will record the new disc using the files that were generated
- by SNAPSHOT.EXE
