Those JVC drives which do not support DAO write all tracks
at once; therefore no link blocks (no errors or noise) is
added between audio tracks; only between lead-in area and
first track and between last track and lead-out area link
blocks are inserted; link blocks at these positions normally
do not cause errors and the resulting discs are perfect

The comments below are valid for firmware revision 1.0a
only. In firmware revision 1.0b or above, all of these
problems are solved.
With firmware 1.0a, these drives do not disconnect from the
SCSI bus during writing. Thus, the SCSI bus is permanently
claimed by the drives, communication with other connected
drives cannot take place. In other words, these drives must
be connected to a separate SCSI adapter. DO NOT connect any
other drive to the same bus. Otherwise writing will not be
reliable because Windows forces hard resets on the SCSI bus
if the other drives do not respond. PoINT CDwrite prints
"Drive not ready" in this case.
With firmware 1.0a, ISRC codes and catalog numbers (UPC/EAN)
are not correctly recorded by the drives.

This requires one of the following recoders:
-> HP 7100I
-> JVC XR-W2040
-> Philips CDD3610
-> Ricoh MP620x
-> Yamaha CRW4260
2) (1998/01/22) New CD-recorders
The current version also supports the following recorders:
-> HP 7100I (NOT: HP 7100E)
-> JVC XR-W2040
-> Matsushita CW-7502
-> Olympus CDS620
-> Panasonic CW-7502
-> Philips CDD3610

-> Plasmon CDR480
-> Plextor PX-R412C
-> Teac CD-R55
-> Yamaha CDR200,
-> Yamaha CDR4260,
-> Yamaha CRW4260
A.2.2 History of version 2.0
----------------------------
1) (1997/03/26) Renaming and deleting files in the target tree
In the early versions these functions of the target tree did not
work correctly. This error has been removed.
2) (1997/03/26) Protection fault and abnormal program termination
In extremely rare cases the early versions caused a protection fault
in module DLLDIR.DLL. This problem has been solved.
3) (1997/03/26) CDread improved
The current version of CDread works faster than older versions did.
This is important especially if tracks are copied from fast CD-ROM
drives.
4) (1997/03/26) New CD-recorders
The current version also supports the following recorders:
-> Ricoh MP6200S
-> SAF CD-R4006
-> Yamaha CDR400
5) (1997/05/27) New CD-recorders
The current version also supports the following recorders:
-> JVC XR-W2020
-> JVC XR-W2022
-> JVC R2626
-> Sony CDU928
6) (1997/06/17) CD-ROM Drives
Some of the CD-ROM drives which had been supported by versions 1.x
of PoINT CDwrite could no more be used in version 2.0. This problem
has been solved.
7) (1997/06/17) NEC CD-ROM Drives
PoINT CDread can now read audio tracks from NEC CD-ROM drives.
8) (1997/06/17) New CD-recorders
The current version also supports the following recorders:
-> Ricoh MP6201S
9) (1997/07/15) New CD-recorders
The current version also supports the following recorders:
-> Nomai 680RW
10) (1997/07/15) JVC/Teac CD-recorders and mixed mode CDs
The versions of CDwrite distributed in May and June had a problem
with reording of mixed mode (data and audio) CDs with JVC and Teac
CD- recorders. This problem has been fixed.
11) (1997/08/08) ATAPI drives (e.g. Sony CDU928E)
In some cases CDread created wrong images of data tracks or WAVE
files with noise when CDs were read in ATAPI drives. Furthermore
CDread could not read at all from some ATAPI drives. These problems
have been solved in this version.
A.2.3 General modifications compared to versions 1.x
----------------------------------------------------
Version 2.x of PoINT CDwrite supports disc-at-once with most of the listed
recording devices. This allows to write perfect audio CDs without noise or
pauses between subsequent tracks.
Furthermore version 2.x still provides, but does no more need the 16 bit
device driver for operation. The configuration without device driver is
recommended for Windows 95.
The MS-DOS program CDCOPY.EXE is still part of the PoINT CDwrite. This
program allows to copy data and digital audio CDs to image files on local
MS-DOS drives. PoINT CDwrite may then be used to write the image files again
to a CD-R.
Additionally, version 2.x of PoINT CDwrite includes a Windows program
called PoINT CDread which provides the same functionality as CDcopy.
Version 2.x utilises huge read-ahead caches in extended memory and progress
bars to make the recording process even more reliable and visible. Especially
the thermal recalibration cycles of large hard disks can no more lead to
data-underrun errors and damaged CD-Rs.
In Windows 3.1x PoINT CDwrite Version 2.x needs 16k-100k bytes of conventional
memory during recording. The size of the needed memory area depends on the
operating environment (see section Installation). The included TSR program
SETBUF.EXE, in combination with the device driver CDROM.SYS, can be used to
solve allocation problems permanently.
For more information about installation of SETBUF and configuration of the
size of the memory buffers please refer to section 'Installation".
PoINT CDwrite can now be prevented from storing the product serial number
on a CD-R. To do this please edit the file 'WINPUB.INI' and replace the
entry "StoreSerialNo=1" with "StoreSerialNo=0".
B. Minimum System Requirements
==============================
PoINT CDwrite Version 2.x can be installed on any INTEL 80386 (or above)
based IBM compatible personal computer which satisfies the following minimum
requirements (normal recording speed of 75 frames per second):
* 8MB system memory
* A diskette drive capable of reading 3.5-inch (1.44MB) diskettes
to read the installation disk
* Microsoft Windows 95
-- or --
MS-DOS 4.x or above,
Microsoft Windows 3.1 or 3.11,
Microsoft CD-ROM Extensions (MSCDEX 2.20 or above)
* A processor clock rate of at least 25 MHz
* One (or more) hard disk(s) offering a minimum sequential throughput
of 400KB/sec on application level and an average access time of
19ms or below
* A supported compact disc recorder
If your compact disc recorder is a SCSI device you additionally need:
* A free PC bus slot to install a SCSI host adapter
for connection of the compact disc recorder
* A bus master SCSI host adapter with ASPI DOS Manager
* SCSI cable
If you change to a recording speed of 150 frames/sec (twice the normal speed),
a minimum sequential hard disk throughput of about 700 KB/sec and an 80386/33MHz
(Windows 3.x) or 80486/33MHz (Windows 95) CPU are sufficient. The throughput is
offered by almost all modern hard disks.
Recording of 300 frames/sec (four times the normal speed, possible with CDR100)
requires a minimum sequential hard disk throughput of about 1600 KB/sec and an
average access time below 15ms. Additionally, the PC should contain an Intel
80486/33MHz (Windows 3.x) or 80486/66MHz (Windows 95) processor (or better).
Suitable hard disk throughput is provided by large SCSI hard disks (1GB and
above) connected to an EISA, VL or PCI SCSI host adapter and by most enhanced
IDE disks.
NOTE: If you are using Windows 3.x then please refer also to section H,
SMARTDRV.EXE.
C. Installation
===============
C.1 Installation in Windows 95
------------------------------
IMPORTANT !!
In older versions of Windows 95 (up to 4.00.950a) PoINT CDread and CDwrite
can support only one connected ATAPI drive. In case you are using one of
these versions and if you want to connect a CD-ROM drive and an additional
CD recorder (e.g. Sony CDU928E), please connect both drives to the same IDE
channel. Configure the CD-ROM drive as IDE master and the recorder as IDE
slave. PoINT CDread and CDwrite will then support the recorder.
IMPORTANT !!
ATAPI drives like Sony CDU928 are fully supported in Windows 95. Unfortunatelly
some software products install an incompatible ASPI manager in Windows 95 which
makes it impossible to access ATAPI drives. In case that PoINT CDread does not
find ATAPI drives although available, please solve the problem by installing
Windows 95 again over the existing installation to replace incompatible by
original modules.
IMPORTANT !!
Please disable the 'auto. notification of media changes' (see control panel ->
system -> device manager -> CD-ROM -> <your recorder> -> properties -> setting).
IMPORTANT !!
In rare cases Windows 95 freezes during recording. This error is cause by an
incompatibility with the virtual memory management of Windows 95. Please
disable the virtual memory before a recording is started if this error occurs
in your environment (see control panel -> system -> performance -> virtual
memory).
Some of the CD recorders identify themselves as SCSI type 4 (write-once)
devices. In contrast to SCSI type 5 devices (read-only CD-ROM device), type
4 devices are not supported by the standard CD-ROM driver of Windows 95,
and Windows 95 will not provide a drive letter for these devices.
If you are using a type 4 device the first time, Windows 95 will ask you to
insert a driver disk for this device. Please advice Windows 95 to not install
a device driver in this case.
Windows 95 drivers for type 4 devices are provided by the vendors of the SCSI
adapters. Adaptec for example offers a driver in a module called CDR4UP.EXE.
This driver can be obtained from Adaptec ('www.adaptec.com' in the world wide
web, or 'go adaptec' in CompuServe).
C.2 Installation in Windows 3.x
-------------------------------
IMPORTANT !!
ATAPI drives like Sony CDU928 or Mitsumi CD-ROM drives are not supported in
Windows 3.x.
IMPORTANT !!
PoINT CDwrite does not work if 32 bit file access is enabled in Windows 3.x
because some MS-DOS systems calls are not supported in 32 bit mode. Please
disable the 32 bit access before you start the performance profiler (see
Control Panel -> 386 enhanced -> virtual memory).
C.3 Hardware Installation of SCSI recorders
-------------------------------------------
This sub-section offers some hints for the configuration of SCSI adapters.
PLEASE READ IT VERY CAREFULLY since most problems are caused by wrong
SCSI configurations. You may find additional hints for your specific recording
device in the other text files on the installation disk.
For a reliable data transfer from hard disks to recorders it is necessary to
read from the hard disks and to write to the recorder in parallel, not
alternatively. Furthermore, the priority of writing must be higher than that
of reading. Parallelism and correct priority are guaranteed if hard disks and
recorder are connected to different host adapters respectively to independent
SCSI busses of a dual-channel host adapter.
Generally, parallel data transfers are supported best by bus master SCSI host
adapters like Adaptec 1540. If your recording device provides enough cache
memory (1MB or more) then you may also use a less expensive PIO adapter like
Adaptec 1510 or 1520. If you use a PIO adapter then you MUST enable the
disconnect/reconnect function.
Remark: On some dual-channel SCSI host adapters the channels are not
independent of each other. Those adapters are not comparable with two
separate host adapters and devices connected to different channels
behave as if they were connected to the same SCSI bus. Please refer
to the documentation of your dual-channel adapter for more information.
If hard disks and a recorder are connected to the same SCSI bus then two
specific features of SCSI become important. (1.) Host adapter and devices
must support the disconnect/reconnect functionality to enable command
execution in parallel. (2.) The SCSI ID (the priority) of the recorder should
be lower than that of the hard disks.
Some restrictions can directly be derived from these requirements. You need a
separate host adapter if
* you own an older Philips or Kodak recorder (not upgraded) since these
recorders do not support the disconnect/reconnect functionality. Please
refer to the User's Manual of the recorder for more information. You
may identify these recorder versions by trying to select the recording
speed (Recorder->SpeedAndMode menu item). If the recorder does not
support this functionality then it's an older version. No SCSI hard disk
must be connected to the same bus in this case.
* you own a JVC XR-W1001 recorder. No hard disk must be connected to the
same SCSI bus in this case.
* one of your SCSI hard disks does not support the disconnect/reconnect
functionality. This hard disk must be connected to a separate SCSI bus.
Please refer to the User's Manual of your hard disks for more
information.
* you boot from a SCSI hard disk since this disk must have SCSI ID=0.
You cannot select a lower SCSI ID for your recorder in this case.
Please verify this restriction by means of the User's Manual of your
host adapter since some new adapters (like AHA-1540C) allow to boot
from hard disks with other IDs, too.
If none of the restrictions apply to your system configuration then you may
connect hard disks and recorder to the same SCSI bus. Enable disconnection
(see User's Manual of your host adapter) and select appropriate SCSI IDs
(for example recorder ID=0, hard disk ID=1, adapter ID=7).
Remark: If you own a JVC XR-W2001, a Sony or a Yamaha Compact Disc Recorder then
you should additionally enable synchronous data transfers (also called
synchronous negotiation) on the SCSI bus to improve the transfer rate.
For other supported recorders synchronous transfers should be disabled.
C.4 Software Installation
-------------------------
C.4.1 Cache Memory
The size of the read ahead cache can be controlled by the 'MaxBufferMemKB'
entry in the .INI file. The default setting is "MaxBufferMemKB=3072" and
allows PoINT CDwrite to allocate 3 MBytes of memory. At the time this
parameter has to be modified manually.
Please note that only physical memory can be used for caching. Therefore
the buffer size cannot exceed the size of physical RAM that is installed
in your computer.
Rule of thumb:
To leave enough memory for other tasks and for Windows itself you should
allow PoINT CDwrite to allocate about half of the physical memory for
caching purposes. The memory is not statically allocated. It is allocated
when PoINT CDwrite starts to write to a CD-R and it is released
immediatelly at the end of the writing process.
C.4.2 Hard Disk Throughput and SETBUF in Windows 3.x
The hard disk throughput depends on the number of blocks that are read with
one read command at once. The higher the number, the better the throughput.
On the other hand, the buffer that is used to access the hard disks must be
placed in conventional memory. This may lead to allocation problems if the
buffer becomes too big.
To circumvent allocation problems and to allow you to configure the size of
buffer (the number of blocks) the utility 'setbuf.exe' from PoINT CDwrite
can be used.
To install this utility, edit or create the file WINSTART.BAT in your
Windows directory and add the line:
C:\WINPUB\SETBUF.EXE /VERBOSE [/SMALL] [/MEDIUM] [/LARGE] [/CDR]
The command line switches have the following meaning:
/SMALL allocates a hard disk buffer of 16KB
/MEDIUM allocates a hard disk buffer of 32KB
/LARGE allocates a hard disk buffer of 48KB
/CDR allocates an additional buffer used for the communication
with the CD-R device during recording; this buffer is only
needed if the vendor of your SCSI host adapter does not
offer an ASPI for Windows interface
Please note: Reboot your system when you have added or modified the command
line and generate the performance profile again. DO NOT START
'setbuf.exe' manually.
In case that the vendor of your SCSI host adapter offers an ASPI for
Windows interface then PoINT CDwrite can use this interface instead of
ASPI for DOS and conventional memory. Prerequisite is that the file
WINASPI.DLL exists in the WINDOWS\SYSTEM directory of your system.
If this interface exists then you should place the command line
C:\SETBUF.EXE /VERBOSE /LARGE
in WINSTART.BAT and modify the line
'UseAspiWin=0' to 'UseAspiWin=1' in
file WINPUB.INI for best performance.
If you encounter any problems with ASPI for Windows (protection faults caused
by ASPI bugs sometimes occured during our test phase with some older ASPI for
Windows interfaces) of if there is no ASPI for Windows for your host adapter
then add the command line
C:\SETBUF.EXE /VERBOSE /LARGE /CDR
in WINSTART.BAT for best performance.
C.4.3 Important Hints
* If you are using Windows 3.x then please read section H, SMARTDRV.EXE.
For shortest formatting times SMARTDRV should be enabled for the drive
that is used to store temporary files.
* If some of your hard disks are connected to a SCSI host adapter with
internal cache memory (cache controller) then please disable caching
before you execute the performance profiler to get reliable results
(see also section E). Caching may be re-enabled after the profile has
been determined and it may also be enabled during recording.
* The program icon of PoINT CDwrite includes a full path specification
of the executable program. Therefore it is not necessary to add the
name of the installation directory to the PATH variable of your
environment.
* It is now possible to use PoINT CDwrite in an unattended mode. This
feature enables you to start writing of CD-WOs out of other applications
or to create your own project specific icons. Please refer to section
3.5 on pg. 37 of the User's Manual for more information.
Additionally you can now prevent PoINT CDwrite from displaying the
CD-WO Summary dialog box before writing is started. To do this simply
replace the line "WriteAttended=1" by "WriteAttended=0" in the text file
WINPUB.INI.
D. MS-DOS 6 and DBLSPACE Drive Compression Utility
==================================================
PoINT CDwrite cannot determine the performance profile of compressed drives
since the throughput of such drives is variable. The throughput varies like
the compression factor of the particular files does. As a consequence,
PoINT CDwrite handles compressed drives exactly like network drives and copies
all files to a partial image file on an uncompressed hard disk drive.
It is recommended to place the source file and directory trees on
uncompressed drives.
E. The performance profiler (PP) in Windows 3.x
===============================================
The PP has been proved to work in virtually all multi hard disk
environments without any user interaction. Unfortunately there are some
rare configurations (especially if compressed drives exist) which are
ambiguous and may lead to erroneous results with respect to correlation
of drives with hard disk devices. The PP prints a warning message in
these cases. If you find the correlation results of the PP to be wrong
in your environment, then you may explicitly specify the appropriate
correlation of drives with disks by use of an undocumented feature of
the PP which is described below.
Furthermore, the PP cannot determine the rotational speed of your hard disk.
PP assumes 3600 RPM by default. This is not a critical aspect because the
parameters determined for faster disks (e.g. 5400 RPM) are worse than they
should be, a wrong assumption cannot cause underflow conditions. However,
you can minimise the size of intermediate files by specifying the correct
value in the WINPUB.INI file (see below).
During execution of the correlation algorithm, the PP searches for a
file named WINPUB.INI in the directory where PoINT CDwrite has been
installed. If present, PP takes the correlation parameters from the file.
The syntax of the parameter file is very simple, it is shown in the following
examples. Empty lines, spaces and tabs are ignored, letters may be given in
both upper and lower case styles. The order of drive (A-Z) and of disk (0-7)
specifications is not of interest, drives and disks are sorted automatically
by the PP.
Example 1 (no compressed drive):
--------------------------------
Imagine two hard disk devices being connected to the PC. Hard disk 0 shall
contain drives 'C:' and 'E:', hard disk 1 shall contain drives 'D:', 'F:',
and 'G:'. The appropriate WINPUB.INI file would contain the text lines:
[correlation]
DISK0=C,E
DISK1=D,F,G
Example 2 (5400 RPM):
---------------------
Imagine the same configuration as in example D1, but hard disk 0 shall
additionally rotate with 5400 RPM. The appropriate WINPUB.INI file would
now look like:
[correlation]
DISK0=5400:C,E
DISK1=D,F,G
Example 3 (one compressed drive):
---------------------------------
Now imagine three hard disk devices being connected to the PC. Hard disk 0
shall contain drives 'C:', 'E:' and 'R:', hard disk 1 shall contain drives
'D:', 'F:', and 'G:', drive 'H:' shall reside on hard disk 2.
The original drive 'C:' shall have been compressed (see MS-DOS 6, DBLSPACE
command) and therefore refers to the compressed file system now (unsupported,
see section C), drive 'R:' shall be the uncompressed host drive of 'C:'.
The appropriate WINPUB.INI file would contain the three text lines:
[correlation]
DISK0=R,E
DISK1=D,F,G
DISK2=H
F. Relaxing the naming conventions
==================================
PoINT CDwrite allows to choose between two character sets that shall be used
to check file and directory names. The ISO 9660 character set strictly conforms
to the ISO 9660 standard and the MS-DOS character set consists of all characters
that are allowed in MS-DOS environments. More options are not available in the
application.
For special applications there are two more options available in the WINPUB.INI
file in section [DLLISO]. These options are active if you use the MS-DOS
character set.
Option 1:
You may add the line "Relax=2" to section [DLLISO] respectively you may
modify an existing entry. In this case PoINT CDwrite does not auto-
matically append a '.' character to file identifiers that do not have an
extension.
Default: Relax=1
Option 2:
You may add the line "MaxPathLength=xxx", 80<=xxx<=127, to section
[DLLISO] respectively you may modify an existing entry. In this case
PoINT CDwrite allows to create pathnames consisting of up to xxx
characters.
Default: MaxPathLength=80
Example: use your favourite text editor and add the following lines to
WINPUB.INI:
[DLLISO]
Relax=2
MaxPathLength=127
G. Known Restrictions
=====================
(1) Orange Book sectors at end of track
CD-R recording devices automatically append two additional sectors
(called run-out blocks) to each data track. These sectors should
actually be ignored by CD-ROM readers, but some CD-ROM devices don't
do so. This causes problems when accessing the last data sectors
of a Volume especially with CD-ROM readers that contain a huge read-
ahead cache.
Therefore older versions of CDwrite unconditionally appended 10 empty
sector at the end of a Volume which was sufficient in most cases. The
new version 2.0 of the Orange Book now recommends to append at least
two seconds post-gap (150 empty data sectors) to each data track.
Since this is only a recommendation we have added the entry
'DefDataPadLength' to section [Settings] of the WINPUB.INI file. This
entry allows you to define the length of the pre-gap area yourself.
[Settings]
DefDataPadLength=<decimal number>
Remark: The defined number of empty sectors is also written to a data
image file when PoINT CDwrite creates this file. Therefore, if you
transfer a data image file to CD-R that has been created by
CDwrite itself the you should set the 'number of empty sectors
to append' field of the 'Parameters of Data Track' dialog box
to 0.
(2) Internal error (PTL corrupted)
Generally, this error message appears if you try to transfer files which are
modified during the formatting process. Since neither you nor PoINT CDwrite
modifies any of your source files while executing, the error occurs if you
write the temporary directories (containing the temporary working files).
Additionally this error message also appears if the File Allocation Table
(the FAT) of one of your hard disks is inconsistent. You should urgently
execute the CHKDSK/SCANDISK command of MS-DOS or a comparable tool of
other vendors if the message appeared and if you're sure that you didn't
write temporary files.
(3) Windows 3.x File Manager
If a CD with an empty root directory is inserted into a CD recorder or a CD-ROM
drive, the Windows File Manager displays the error message: no disc inserted.
The DOS "DIR" command correctly reports that no files are found.
(4) Target Tree
When deleting directories from the Target Tree, the horizontal scroll bar may
disappear causing parts of the tree hierarchy to be invisible. To recover from
that situation please close and re-open the Target Tree window.
(5) Pauses at the beginning of digital audio tracks
The length of the pause at the beginning of digital audio tracks (the pre-gap)
can be influenced. This feature is only supported by JVC XR-W1001 and XR-W2001
(no restrictions) and by Philips CDD522 and Kodak PCD225 (minimum length is
five frames or 5/75 seconds). Other recorders do not support this feature at
the time.
The first audio track on a pure digital audio disc should always start with
a pause of 150 sectors (default). A pause of less than 150 sectors leads to
a malfunction of various consumer CD players.
Furthermore either a pause of about 5 sectors should be placed at the
beginning of any other audio track or the source PCM sequence should start
with about 3000 sample frames containing silence (0'es) to avoid noise
and high error rates while a CD player crosses track boundaries.
H. SMARTDRV.EXE in Windows 3.x
==============================
Hard disk caching software like SMARTDRV.EXE of Microsoft (or corresponding
programs of other vendors) improve the performance of the hard disk subsystem
significantly while you are running applications which repeatedly access the
same locations on your hard disks. Unfortunately the sequential throughput of
a hard disk is decreased dramatically by caching software, and a high sequential
throughput rate is very important during recording of CD-WOs. If SMARTDRV.EXE is
installed on your computer system then it is possible that PoINT CDwrite cannot
use the maximum recording speed of your recorder even on machines which satisfy
the minimum system requirements.
There are two possibilities to solve this problem. First you can choose a lower
recording speed. Second you can disable SMARTDRV.EXE either permanently or
during recording only.
Remark: In case that you are using caching software of other vendors please
check whether this software also decreases the throughput. You can
do this by generating the performance profile twice, once with installed
and once with de-installed caching software.
Note: SMARTDRV.EXE of Windows 3.11 or MS-DOS 6.x also supports CD-ROM drives. To
enable caching of CD-ROM data SMARTDRV.EXE has to be installed after
MSCDEX in your AUTOEXEC.BAT file. We recommend to cache CD-ROM data, too,
since the amount of time-expensive positioning operations is then
minimised.
I. Incompatibility between XR-W2001 and Toshiba CD-ROM Drives
=============================================================
CD-BRIDGE multi-session discs written by XR-W2001 revisions up to (today) 2.35
cannot be read in Toshiba 3501 and 3601 CD-ROM drives if the data tracks are
recorded in mode 2. In contrast multi-session discs written in mode 1 are
readable in the Toshiba drives and should be readable in any CD-ROM drive, too,
although they do not conform to the CD-BRIDGE specification.
Hence, to offer a work-around for the incompatibility between JVC and Toshiba
a new option has been added to PoINT CDwrite which allows to write multi-session
discs in mode 1. You may select this option by adding the following line to
section [DLLISO] in the WINPUB.INI file:
[DLLISO]
BridgeInMode1=1
