DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 6
1. INTRODUCTION:
DISK COPY FAST is a one pass diskette duplication utility which
makes copies of 1.44 MB, 720 KB, 1.2 MB and 360 KB diskettes.
The speed of DISK COPY FAST is incredibly fast. For example,
using DOS command DISKCOPY to duplicate a 360 KB, 1.2 MB, 720
KB or 1.44 Mb diskette, assuming diskette shuffling doesn't
take any time, will take 43%, 50%, 42% or 57% longer than
using DISK COPY FAST. Add up the shuffling time the saving
becomes unbelievable. See page 14-15 for details.
More importantly, DISK COPY FAST achieves its high performance
by precise timing, not by sacrificing compatibility. Every
single read, write or format is done following the industry
standard, strictly, no compromise!
Can you ask for anything more?
See the next section for other outstanding features.
DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 7
2. MAIN FEATURES
*** Performs the DOS commands FORMAT, DISKCOPY and DISKCOMP
all in one single pass.
*** Friendly and informative user interface. No need to go
through lengthy DOC file and still couldn't remember all
the options and switches.
*** Hot keys designed to make your backup much easier.
*** Utilizes extended memory (XMS) for faster speed and to
save your hard disk from unnecessary wear and tear.
*** Creates exact image file of diskette.
*** Fast mode that reads and writes only the portion of
diskette which contains data and does not waste any time
reading and writing the empty portion.
*** Some degree of protection against boot sector virus. (See
page 18. Although not complete, this sometimes can be a
life-saver.)
*** High efficiency. When copying a 1.2 MB diskette in a
system with 590 KB free memory, DISK COPY FAST easily
stored 34 tracks while another diskette copy program could
only store 17 tracks of data in conventional memory.
*** More features waiting for you to find out. The more
experienced you are the better the DISK COPY FAST stands
out.
If you duplicate large quantity of diskettes on regular basis
there is more for you. Check the features of DISK COPY PLUS,
a professional version of DISK COPY FAST, on page 21.
DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 8
3. SYSTEM REQUIREMENT AND COMPATIBILITY
To run DISK COPY FAST you need at least an IBM AT or compatible
with 286 or better CPU. The results of using the program on an
older computer (PC or XT class) is unknown.
At least 128 K Bytes of free conventional memory is required.
In addition, the total of free conventional and extended memory
plus free current disk (hard disk or RAM disk) space should be
at least 80 K Bytes more than the diskette you want to
duplicate. If you intend to use extended memory, some kind of
extended memory driver, such as HIMEM.SYS which comes with DOS
5.0 or QEMM which you need to purchase separately, is required.
Extended memory can be accessed without any driver but it is
dangerous to do so.
The program has been tested on machines with different hardware
and BIOS configuration. It hasn't, however, been tested on any
old PC or PC XT.
DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 9
4. HOW TO INSTALL AND RUN DISK COPY FAST
It's easy! Just copy DCF.EXE to one of your path directories
(defined in your AUTOEXEC.BAT file) then you can run the
program anywhere you like. If you copy DCF.EXE to any other
directory you'll need to attach to that directory before you
run the program.
To run the program type "DCF <CR>". <CR> means "carriage
return" or the "enter" key. If you have a color system but
prefer black and white, type "DCF mono <CR>" or simply "DCF m
<CR>" and it will run in monochrome mode. If you have a mono-
chrome card you don't need this switch as the program will auto
detect the video card and run in monochrome mode.
That should take care of at least 99% of users. The default of
the program assumes that you have a reasonably slow machine, up
to 9 times slower than my 33 MHz 386 machine. Note that the
speed of a PC depends on more factors than just CPU clock
speed.
For the remaining maybe 1% of users, your machine is really
slow and you wonder how fast it can go when copying a diskette.
Try running the program with a parameter ranging from 2 to 9,
the slower the machine the larger the parameter. At DOS prompt,
type "DCF p" where p is the parameter you choose.
DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 10
5. HOW TO USE PULL-DOWN MENU IN DISK COPY FAST
After you type "DCF" or "DCF m", the main menu shows up.
5.1 SELECT : To select a command, use the arrow keys. In color
mode you can also press the highlighted letter. In mono-
chrome mode you can't see highlighted letters. Instead,
press the first letter of a command with three exceptions,
A for "Drive A", B for "Drive B" and m for "Format".
5.2 EXECUTE : To execute a command, press enter key after you
have selected the command.
5.3 ESC key : You can press the ESC key to interrupt a Read or
Write action. If the program is not busy doing something
this will bring you back to start-up menu. If you are
already in start-up condition the program will quit.
DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 11
6. WINDOWS
There are three windows in DISK COPY FAST.
6.1 RESOURCE window : This window shows you the resources in
your system which can be utilized for duplicating a
diskette. Inside this window, "Con mem" shows you the size
of free conventional memory, "Ext mem" shows you the size
of free extended memory and "Cur dsk" shows you the size of
free space on current disk (hard or RAM disk.) It also
shows you the capacities of available diskette drives.
6.2 OPTION window : It shows you current read/write options.
See command "Option" in next section for details and how
to change them.
6.3 INFORMATION window : It shows you the status of the loaded
source diskette. For example if it says 61 out of 80 tracks
it means the source diskette has 80 tracks but only the
first 61 tracks contains useful data and the last 19 tracks
are empty. Then it will show you how these 61 tracks are
loaded in your system. For example it may says 34 tracks in
conventional memory, 20 in extended memory and 7 on current
disk. It also shows you other information such as the time
it took to perform last read, write (in seconds) and how
many copies you have made so far.
Note that the information window won't be visible until you
have a source diskette loaded in your system. Also note
that the track numbers shown when reading or writing a
diskette are 0 based which means if the diskette has 80
tracks the track numbers will be 0 to 79 instead of 1 to
80.
DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 12
7. COMMAND REFERENCE
7.1 Read: Loads the source diskette data from drive A or B, or
from an image file created previously by DISK COPY FAST to
conventional memory and extended memory and then hard disk.
7.2 Write: Writes loaded source diskette data to drive A or B,
or an image file.
7.3 Compare: Compares the loaded source diskette with another
diskette in drive A or B, or an image file.
7.4 Option: Includes three subcommands for you to set read/
write options. "Format ON" means format target diskette
before writing to it. "Compare ON" means perform a read
back and BYTE-BY-BYTE comparison immediately after writing
a track to target diskette. "Fast ON" means don't read/
write empty portion of source and target diskette. Note
that subcommands "Format" and "Compare" affect write only
while "Fast" affect both read and write. The current status
of these options is shown in the OPTION window.
DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 13
8. HOT KEYS
When you purchase a software, you know how important it is to
make a backup. So you FORMAT, DISKCOPY... shuffle, shuffle.
After all the hard work you still feel a little uneasy. So you
DISKCOMP and again busy shuffling. What a waste of time and
energy!
Let DISK COPY FAST do the hard work and save time for you. Type
DCF to bring up the menu, press F1 (or F2) and then alternate
between source and target diskettes. When you are finished just
press the ESC key. It's fast. It's easy. No more shuffling.
You don't need to repeat the same commands sequence and all the
switches over and over again. Best of all, the BYTE-BY-BYTE
comparison is already done. No need to DISKCOMP.
Sounds good? Give it a try. Just remember F1 (function key) is
for copying a sequence of diskettes in drive A and F2 is for
copying a sequence of diskettes in drive B. If you want to
change the read/write options do it before using the hot keys.
Note : 1) When DISK COPY FAST prompts for a source or target
diskette it will start reading or writing as soon as
it has sensed that the drive door has been opened
(remove old diskette) and then closed (insert new
diskette.)
2) Because of the auto-sensing feature mentioned above,
no matter how many source diskettes you need to
backup the whole operation requires only two
keystrokes, the F1 (or F2) at the beginning and ESC
key at the end. Between these two keystrokes all you
have to do is alternating between the source diskette
and target diskette.
DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 14
9. BENCHMARK AND COMPARISON
9.1 Benchmark, HOW FAST CAN IT GO
The following results are from a 386, 16.7 MHz (33 MHz with
Turbo mode turned off) compatible machine with 1.2 MB and 1.44
MB diskette drive. The numbers are the time (in seconds) for
DISK COPY FAST and DOS commands to perform the specific task.
In each cell, the 1st number is for a 100% full diskette the
second number (in parentheses) is for 25% loaded diskette.
The time for DOS commands does NOT include diskette shuffling
time.

Note : (1) Time for DOS commands does NOT include diskette
shuffling time.
(2) Under the "task" column in the above table, R stands
for Read, W stands for Write, F stands for Format
and C stands for BYTE-BY-BYTE comparison.
(3) DISK COPY FAST does not have command for formatting
a new diskette. The above measure for "format only"
was taken by copying a empty diskette (no data) to a
new diskette with Option Format ON and Option Fast
ON.
(4) Performance varies on different machine.
DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 15
9.2 Comparison, HOW MUCH CAN YOU SAVE
Again, we give DOS commands the best possible conditions. We
assume diskette shuffling doesn't take any time. When there is
more than one way to have the work done using DOS commands, we
choose the one with the shortest time. For example, while you
can use DISKCOPY to copy form source to unformatted target, it
would be faster to format the diskette first before copying and
this will be the DOS method we use for comparison.
Still, there are some problems with DOS commands which we can't
help. For example, DOS commands have no FAST mode and can't
read a source once and write target many times.
The following tables show how much longer, in percentage, it
takes using DOS commands than using DISK COPY FAST. The first
table is for a 100% full diskette and the second table is for
a 25% loaded diskette. In each table, the first row is for
straight copying, no format, no comparison, the second row
includes comparison but not formatting, the third row includes
formatting but not comparison. The last row includes both.

DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 16
10. WHAT IS AN IMAGE FILE ?
When you format a 1.2 M Bytes diskette, it actually contains
1,228,800 bytes but DOS tells you only 1,213,952 bytes are
available. Where are the other 14,848 bytes? They are used by
DOS to store information about the format, allocation of files
and root directory of the diskette. When you use COPY or XCOPY
to copy files from one diskette to another this information is
not copied. Also the file allocation may be different. Same
file may occupy different sectors on the two diskettes.
An image file is created by reading the source diskette
sector-by-sector, track-by-track in the original order. It
contains every bit of information of the source diskette.
Thus, the size of the image file of a 1.2 MB diskette will be
exactly 1,228,800. This file can be stored on the hard disk or
on tape. (You can use some kind of compression utility program
such as ARJ, LHA or PKZIP to save storage space if you like)
Why do I want to do that? You ask. I'll describe one possible
applications here.
For archives purpose: You know the importance of backing up
the software you bought. How do you do that? DISKCOPY them to
another set of floppies? You can do that but what if you
already have hundreds of floppies around? If you are rich you
can save image files to hard disk. If you are not so rich save
them to tape. With compression one tape (costs about $20) can
hold as many as 200 image files of 1.2 MB floppies yet the
size is smaller than an audio cassette. Several months from
now if your original diskettes are damaged you can retrieve
image files from the tape, write to new diskettes and you have
an identical copy of the original (this won't work if the
original is copy-protected) Of course tape drives are slow,
but this is archives and you are not supposed to have to do
it often.
DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 17
11. ABOUT EXTENDED MEMORY
To use extended memory (i.e. memory beyond 1 MB) you need the
following.
1. At least IBM PC AT or compatible with 80286 or better CPU.
2. Of course you need to have extended memory installed.
3. For safety reason DISK COPY FAST also requires that you
have some kind of extended memory manager (or driver)
installed which conforms to the Microsoft eXtended Memory
Specification (XMS), version 2.0 or above. You can use
HIMEM.SYS which is included with DOS 5.0 so you don't need
to spend extra money to get one. You can also use QEMM386
or any other memory manager as long as it conforms to the
XMS specification.
DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 18
12. ABOUT BOOT SECTOR VIRUS PROTECTION
!!! IMPORTANT : Do not assume a diskette is virus-free just because
it is accepted by DISK COPY FAST.
As a bonus, DISK COPY FAST also gives you some protection
against boot sector virus such as Michaelangelo. DISK COPY
FAST was never intended to be an anti-virus program and by no
means should this kind of protection be considered complete.
Having said that, here is how it works.
Every diskette contains some important information in the boot
sector which is usually damaged when infected by a boot sector
virus. If DISK COPY FAST finds any invalid data in the boot
sector it will warn you and refuse to copy the diskette. You
can then use an anti-virus program to check it and/or kill it.
This feature can be very helpful or even a life-saver when you
don't think so but you actually have a boot sector virus on
a source diskette.
A side effect of this feature is sometimes you have a virus-
free diskette with invalid data in boot sector and DISK COPY
FAST refuses to copy it. For example, the way some anti-virus
programs kill a boot sector virus is to write a constant value
on the boot sector. The virus is killed but the boot sector
information is never recovered. For your protection DISK COPY
FAST will not accept a diskette if it has any doubt.
This feature actually saved me twice. I believe it will save
some of you too.

13. EXAMPLES
In the following examples "xxx|yyy" means you select and
execute first level command "xxx" followed by its subcommand
"yyy". The "Drive A" subcommand in these examples can be
replaced by "Drive B".
1. How to make a single copy form source to target diskette.
(1) "Read|Drive A" to read source diskette.
(2) "Write|Drive A" to write target diskette.
2. How to read one source diskette and write many target
diskettes.

above)
(2) Each working session perform a read once and write many
(see 4)
6. How to backup a sequence of diskettes such as the original
diskettes of the software you just bought.
(1) Use "Option" and its subcommands "Fast", "Compare" and
"Format" to set desired read/write option. see page 12.
(2) Press function key F1 (or F2) if you want to use drive
A (or drive B). See page 13.
DISK COPY FAST Version 3.0 Copyright 1992 Chang Ping Lee page 20
14. QUESTIONS AND ANSWERS
1. Q: After I made a copy using DISK COPY FAST I use DOS
command DISKCOMP and it says that the two diskettes
are not identical. What's wrong?
A: If you turn Fast mode ON (default) DISKCOPY will only
copy the portion of source diskette with useful data to
target. The empty portion is not copied and this is
what DISKCOMP complains about. If you don't like this
for any reason, just turn the Fast mode OFF. Then every
track will be copied and the whole diskette will be
identical to the original.
2. Q: I just installed more extended memory in my computer
but DISK COPY FAST still says that I don't have any.
A: There are other requirements. See page 17 for details.
3. Q: My PC is slow. Can it achieve the same performance as
described in this documentation?
A: When you copy a diskette the bottleneck is diskette I/O
not CPU clock speed. DISK COPY FAST has been tested on
several old 286 12MHz PC compatibles. Most of them
showed quite impressive results. On the other hand, the
results on a 20 MHz 386SX were significantly slower in
some testing categories. If the performance on your
system is not as good, it has more to do with mother-
board design and/or hard disk speed (if you don't have
enough memory to hold the contents of the entire
diskette and your hard disk is very old and slow) than
with CPU clock speed.
4. Q: I have an old PC (or XT) can I use DISK COPY FAST on
it?
A: DISK COPY FAST has been tested on machines with a 286
or above only. If you use it on older machine results
can be unpredictable.

15. INTRODUCING DISK COPY PLUS
DISK COPY PLUS is the professional version of DISK COPY FAST.
It includes all the features of DISK COPY FAST plus some
advanced features.
To many people, large quantity diskette duplicating means that
you need to buy four-disk copier. Not so any more. With DISK
COPY PLUS you can assemble two low-end 286 PCs each equipped
with two floppy drives at much lower price and achieve much
higher copying speed. Not only do You get higher productivity,
but also that you get two computers instead of a special
purpose machine.
DISK COPY PLUS is even better for you if you only need to copy
small quantity of the same source diskette every day. Consider
the low cost, incredibly high speed (see page 14-15 in
DCF30.DOC) and other powerful features (explained later), DISK
COPY PLUS is hard to beat.
One of the most powerful features of DISK COPY PLUS is
customized hot keys. You define up to 10 hot keys according
to your special needs.
A feature similar to hot keys but requiring no keystrokes is
the AUTOEXEC feature. You define what DISK COPY PLUS should do
automatically when you run the program, just like AUTOEXEC.BAT
does when you reboot your computer.
For example, DISK COPY PLUS can be configured so that each
time you type DCP at the DOS prompt it will read a image file,
set up a serial number (explained later), define read/write
options and then prompt for the target disk. You then insert
the target into drive A:, close the door and it will start
copying. You can use one drive only or you can alternate
between two drives, if they both support the format of the
image file (source disk).
Imagine. Just type DCP and change the diskette 100 times! That
is all you need to do to make 100 copies, each one double
checked with a BYTE-BY-BYTE comparison to make sure they are
identical to the original, except for the serial number. This
high degree of automation means that you can save time for
more creative work, or you can hire someone who knows nothing
about computers to do the copying for you.

Another nice feature of DISK COPY PLUS is automatic serial
number assignment. Some people like to change the disk serial
number that DOS shows you when you use the DIR command. Other
people like to imbed a unique serial number in their product
so that whenever and wherever they see a copy of their product
they know where it came from. DISK COPY PLUS allow you to do
either or both types of these serial numbers. In addition, it
provides other tools to help you find the right location for
imbedding serial numbers and show you the imbedded serial
number on any duplicated diskette. This feature can be done
automatically using the hot keys or AUTOEXEC features.
DISK COPY PLUS also keeps track of serial number of EVERY
image file for you so that you don't need to specify the
serial number each time you run the program. It also keeps
a log file for your diskette duplication. With a little
editing (you add the distributing destination) the log file
becomes a nice record of your diskette distribution.
For those who prefer imbedding serial number in individual
files DISK COPY PLUS also comes with a utility program which
helps you imbed a file or multiple files in a project. This
utility also include the bookkeeping features so that Your
work will be reduced to minimum.
If you duplicate diskettes on regular basis you also need a
head cleaning utility. While some head cleaning utility
programs claim that they work, DISK COPY PLUS actually shows
you that it works. You will have the confidence that you give
your diskette drive the best care possible.
DISK COPY PLUS also provides commands that allow you to see
the contents of a diskette, image file or diskette loaded in
memory.
With all these features, the registration fee for DISK COPY
PLUS is only $50 plus shipping and handling.
