	17. INTRODUCING OTHER FINE PRODUCTS


	    17.1   DISK COPY PLUS


	    "I really find your DISK COPY PLUS a very very fine program. It
	    literally has saved me a lot of time copying diskettes."
					    -----   one user, United States


	    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 high-price copier. Not so any more. With DISK
	    COPY PLUS you can assemble two low-end 286 PCs each equipped
	    with up to four 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
	    a small quantity of the same source diskette every day.
	    Consider the low cost, incredibly high speed (see section 10 in
	    DCF43.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 an 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. After you have done with one format, at the press of
	    one key it converts the source to another format, say, from
	    720KB to 360KB, and continue copying in another drive.


	    In this example, it takes only two keystrokes (one to change
	    format, another to quit.) to produce as many 360KB and 720KB


	    target diskettes as you like. Each copy produced can have a
	    unique serial number and each copy can be 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.
	    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 and VERIFY 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 distribution destination) the log file
	    becomes a nice record of your diskette distribution.


	    The power of DISK COPY PLUS keeps growing. Listed below are
	    some other powerful commands.

	    The DIAG command checks boot sector, file allocation table
	    (FAT) and directory structure and provides reports for diskette
	    usage and fragmentation.


	    The CONVERT command convert diskette image from one format to
	    another, so long as the data on original format can fit into
	    the new format. For example, a 1.44 MB disk can be converted to
	    360 KB diskette if the data on the 1.44 MB disk does not exceed
	    the total data space on a 360 KB diskette.


	    The DEFRAG command performs defragmentation on a diskette. It
	    does more than just sectors swapping. The entire diskette is
	    checked thoroughly for any possible way of compaction. The
	    result is a perfect with no waste of space and no fragmentation.


	    The DUMP command lets you move around the loaded diskette at
	    very high speed. You can use it to check the contents of a
	    diskette or verify the imbedded location(s) of a serial number.


	    DISK COPY PLUS also provides commands that allow you to see
	    the directory of a diskette, image file or diskette loaded in
	    memory.

	   17.2   DISK UTIL PACK


	   "Your Disk Utility Package has many useful features. I was
	   amazed by the copying speed of the F2H & H2F. They are time
	   saving utilities. Great to use."     -----  one user, Singapore


	   DISK UTIL PACK is a collection of five high performance and
	   useful diskette utility programs. For example, the author uses
	   H2F every day for filling orders for DISK COPY FAST and related
	   products.


	   F2H  (Floppy to Hard disk)

	   A utility to copy a diskette to hard disk or RAM disk at very
	   high speed. See the following table for benchmark results.


	   H2F  (Hard disk to Floppy)

	   A utility to copy recursively from current directory on hard
	   disk or RAM disk to a diskette at very high speed. This program
	   combined with F2H is ideal for backing up a small directory.
	   See the following table for benchmark results.



				 H2F vs XCOPY      F2H vs XCOPY
	      --------------------------------------------------
	       Case 1 (1.2MB)     8  vs  40         8  vs  17
	       Case 1 (1.44MB)    9  vs  50         9  vs  19
	       Case 2 (1.2MB)     9  vs  33         9  vs  18
	       Case 2 (1.44MB)    8  vs  40         9  vs  19

	       Note: (1) Case 1 contains 36 files and no sub directory.
			 Case 2 contains 13 files in 21 sub directories.
			 Total file size in both cases is about 300 KB.

		     (2) Performance varies on different systems. The
			 above benchmark results are provided as an
			 example, NOT a guarantee.

		     (3) The above results were measured with a RAM disk
			 on a 33 MHz 386 compatible system.

	   FMT

	   A utility to format 360KB, 1.2MB, 720KB and 1.44MB diskettes.
	   Features include no keyboard operation, serial number assignment,
	   label assignment and bad sectors handling.

	   You type the program name at DOS prompt to start and press the
	   ESC key to end, no keystroke in between!

	   The serial number and label can be assigned incrementally with
	   a text file which stores the serial number and label for the
	   next diskette to be formatted. You can keep more than one text
	   file for this purpose. Before exit, FMT will update the file
	   automatically.

	   Conventionally, a cluster is marked as bad cluster if the
	   formatting program fails to access after three tries. FMT,
	   however, adopts a more strict policy to ensure that your
	   valuable data won't be saved on places which are bad or about to
	   turn bad. FMT will try three times too. The difference is that
	   if FMT fails to access a sector in the first try it will mark
	   the sector bad and tell you how many tries has failed.


	   CLN

	   A utility to make full use of cleaning kits sold by 3M, Memorex
	   and other companies.

	   Without CLN, all you can do is to use commands such as DIR to
	   get the disk drive moving and bring head into contact with the
	   cleaning disk and the cleaning solution on it. However, there
	   are two problems that only CLN can help you.

	   Firstly, how many DIR commands you need to keep typing to keep
	   the disk head in contact with the cleaning disk for 30 to 60
	   seconds? With CLN you only need to type CLN to start and press
	   the ESC to end the process, no keystrokes in between. CLN also
	   "reads" both sides of every "track" to make full use of your
	   cleaning kit. Try CLN once and you will know how many keystrokes
	   it can save for you.

	   Secondly, since there is no data on the disk DOS will stop after
	   it fails to access the first track. This means you may only be
	   using 0.625% of the surface of your cleaning disk! (There are 80
	   tracks on a high density drive. Each track has two sides and you
	   are only using one side on the first track.)



      DISK COPY FAST    Copyright 1992, 1993    Chang Ping Lee       page 32






	   CLN not only forces your system to keep on "reading" different
	   tracks on the cleaning disk and thus clean the head more
	   thoroughly but also provides you simple and easy ways to verify
	   that it does what it claims. Your will have the confidence that
	   you give your diskette drive the best care possible.


	   CHDK (CHeck DisKette)

	   A utility which gives detailed information about a diskette. It
	   shows you the information contained in the system area of the
	   diskette, check the integrity of the system area, gives you
	   detailed layout of system area, root directory and data area and
	   then give you a report of the fragmentation on the diskette.

	   The program also shows you other important or interesting
	   information about a diskette. For example, it shows you the
	   sectors, clusters and tracks with active data, maximum number of
	   root directory entries.

	   CHDK shows you lots of information packed in one screen.
