INTRODUCTION
Is this you? You have one 5 1/4" floppy drive and/or one 3
1/2" drive. When you go to do a diskcopy on any disk larger
than 360KB, you do the 'floppy shuffle'. You know, 'Insert
Source Diskette'; drive whirrs for a moment; 'Insert Target
Diskette'; drive whirrs some more; 'Insert Source Diskette';
etc., etc., etc! What's more, *EVERYTHING* is copied from the
diskette: Empty cylinders as well as ones with data. And what
if you want to make another copy of the same diskette? When the
first copy is done, you have to repeat the whole process
including re-reading the Source diskette all over again. What a
waste of time!
If all this sounds familiar, then CPYDSK is for you. CPYDSK is
designed to avoid the 'floppy shuffle'. Here are some of the
features of CPYDSK:
* CPYDSK copies the Source data first using as much conventional
DOS memory as available. If necessary, expanded memory, if
present, will then be used. If expanded memory is not present
or is exhausted, auxiliary disk space (usually a hard
disk) will be used, if that, too, is present.
* By default, CPYDSK will copy only those cylinders that have data
on them. You have the option to override this and make an
exact duplicate of the Source diskette if you wish.
* If the Target diskette requires it, CPYDSK will format the
Target diskette while copying the data. When the Target disk
requires formatting, CPYDSK will format all cylinders whether
or not it is only copying Source cylinders with data on them.
* If all the Source data could be read in one pass, CPYDSK will
give you the option to make multiple copies without re-reading
the Source data.
* CPYDSK will, at your option, do a read-after-write verification
of the data written to the Target diskette.
* CPYDSK options can be set using a menu or from the command
line. Most command line settings can be reviewed and changed
at the menu or you can set a command line switch to skip the
menu and go directly to the copy operation. This last option
allows easy customizing via batch files.
INSTALLING CPYDSK
1. Read the READ.ME file for last minute items and a list of all
CPYDSK files supplied with this version.
To make a hardcopy of the READ.ME file, enter
COPY READ.ME PRN
2. The only file needed to run the program is CPYDSK.EXE. To
install CPYDSK, just copy CPYDSK.EXE to the desired disk and/or
subdirectory.
For example, assume your CPYDSK files were on a floppy disk in
drive A: and you wanted to install it on your hard disk C:.
Entering the following command from DOS will accomplish that.
COPY A:CPYDSK.EXE C:CPYDSK.EXE
Or, let's say you have a subdirectory named \UTILITY on your
hard disk C:. You can install CPYDSK in that subdirectory by
entering:
COPY A:CPYDSK.EXE C:\UTILITY\CPYDSK.EXE
STARTING CPYDSK
CPYDSK is invoked from the DOS command line by entering its
name, CPYDSK, optionally followed by command line parameters.
If you get the error message, "Bad command of filename", it is
because one of the following reasons:
1. The command was issued when not logged onto t
