New to Unix, need to copy disc using DD

New to Unix, need to copy disc using DD
Hello,
I'm new to Unix
, but very comfortable with computers, we have a old ScoUnix system at work and we have no IT person, although we have limited basic knowledge of commands we are by far not experts. We have called around to have someone work on this but to date have not found anyone.
The hard drive we have now is about 10 years old and we would like to copy everything, a complete image, over to a new(used) drive of the same size 1.79 gig.
I have seen the DD command and wonder if this would be a correct one to use to make a copy.
Time for copy is not an issue I have read DD is slow but that is no problem.
Can someone walk me thru the commands to make a disk copy using DD or another command. I have looked at some of the examples on this forum, but need it spelled out a little better.
Please understand that I am a complete novice to Unix, so make it as simple as possible
Thank You,
Bill

mcat
mcat(1) General Commands Manual mcat(1) Name mcat - dump raw disk image Note of warning This manpage has been automatically generated from mtools's texinfo documentation, and may not be entirely accurate or complete. See the end of this man page for details. Description The mcat command is used to copy an entire disk image from or to the floppy device. It uses the following syntax: mcat [-w] drive: Mcat performs the same task as the Unix cat command. It is included into the mtools package, since cat cannot access remote floppy devices offered by the mtools floppy daemon. Now it is possible to create boot floppies remotely. The default operation is reading. The output is written to stdout. If the -w option is specified, mcat reads a disk-image from stdin and writes it to the given device. Use this carefully! Because of the low-level nature of this command, it will happily destroy any data written before on the disk without warning! See Also Mtools' texinfo doc Viewing the texi doc This manpage has been automatically generated from mtools's texinfo documentation. However, this process is only approximative, and some items, such as crossreferences, footnotes and indices are lost in this translation process. Indeed, these items have no appropriate repre- sentation in the manpage format. Moreover, not all information has been translated into the manpage version. Thus I strongly advise you to use the original texinfo doc. See the end of this manpage for instructions how to view the texinfo doc. * To generate a printable copy from the texinfo doc, run the following commands: ./configure; make dvi; dvips mtools.dvi * To generate a html copy, run: ./configure; make html A premade html can be found at `http://www.gnu.org/software/mtools/manual/mtools.html' * To generate an info copy (browsable using emacs' info mode), run: ./configure; make info The texinfo doc looks most pretty when printed or as html. Indeed, in the info version certain examples are difficult to read due to the quoting conventions used in info. mtools-4.0.13 28Feb10 mcat(1)
