[Updated 21 Dec 83 - Now works for copy to hard 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.

leave the write-protect on the master)
(Just follow the prompts in the program, except when they ask
you to remove the write protect tab)

The original version of this file did not have the mod at 3375, and the
copy to hdisk would bomb. With the help of a friend who told me it
wouldn't copy to his hdisk, I found the cause. The above procedure will
work for backup to floppy or hard disk. Another way to unprotect Word
gets rid of the need for any weird disk formats--but it is MUCH more
complicated to do. Enjoy!

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read:
