Here are two different ways to get around the copy protection
on Microsoft's Word disk.
********************************************************************
The protection scheme for MS word is quite good. The last track
is formatted with 256 byte sectors. One sector, however, has
an ID that says it is a 1K sector. If you try to read it as a 256
byte sector, you'll get a sector not found. You can read it as a
1K sector with a guaranteed CRC error, and you will get the data
and other sector overhead from 3+ sectors. They read it as 1K, and
use the bytes after the first 256 for decryption. These bytes
constitute the post-amble of the sector, the inter-sector gap, and
the preamble to the next 256 byte sector. If it's not formatted
with the correct inter-sector gap, the decryption key is
different and the incorrectly decoded program bombs.
The best way around this is to modify the MWCOPY program so it
will let you make more than one copy. The below mods will let
you make as many backups as you want (and you can leave the
write protect tab on your master disk). Of course, this method
should only be used by registered owners of Word. If you, or any
of your IMF force is killed, the secretary will disavow any
knowledge of these patches.
We will copy MWCOPY to another disk, using another name (MWCP) so
you'll know it's the special version, and then modify MWCP.
(with master disk in A:, B: has any disk with debug on it)
A>copy mwcopy.com b:mwcp.com
A>b:
B>debug mwcp.com

(Just follow the prompts in the program, except when they ask
you to remove the write protect tab)
I think this will also work for the hard disk copy portion. Another
way to unprotect Word gets rid of the need for any weird disk formats.
But it is MUCH more complicated to do. Enjoy!
**********************************************************************
I have discovered that if you use one of the copy programs to
copy word and then run the install program for the hard disk
from that copied disk, word will let you run the install to a
diskette as well. It seems that after you have done a hard disk
install, Word doesn't check the validity of the copy protect for
the next install. I had originally installed to my hard disk
from a copy of my original, but until recently I hadn't tried
the diskette install. I had however, tried the diskette install
from the copied diskette first and found that the resulting
installed copy of Word would not run. While this does not
solve the problems created by Word's copy protect, such as not
being able to run in a ramdrive, it does give you extra backup
copies and possibly keep you from having to go back to Microsoft
for a replacement.
As far as I can tell, this will only work on a virgin copy of
Word, or one which was copied before the install was run, since
after an install is run, Word won't let you do a second one.
Using this method, you can create as many copies as you care to from
MWCOPY, so long as you do a hard disk install for each one before
you attempt to do the diskette install.
