Disklavier

Carol

Let me explain!!

This is what Yamaha does.
Take one "normal" formated floppy and record your .fil files to it.
This will play back in any piano AND in a PC. Not a good idea to let 
peolpe copy it - so destroy the boot sector by making it blank and 
hide all of the files. That way the PC thinks it is unformated and 
can not read it. 
The Disklavier and CVPs do not need the boot sector so they can read 
them ok.
As far as I know any piano should be able to read the files on a disk 
with a working boot sector. They have always worked with all of the 
CVPs that I have had. 
I have never owned a Disklavier so I don't know about that. BUT they 
must work, as the DVKutils program does just that.

The file extensions were indeed .fil

What did I write?  

The boot sector consists of data to tell the PC:

1 System ident
2 number of bytes per sectors
3 number of sectors per cluster
4 number of reserved sectors at begining
5 number of copies of the FAT
6 number of root directory entries
7 Total number of sectors on disk
8 mrdia descriptor
9 number of sectors per FAT
10 number of sectors per track
11 number of sides
12 number of reserved sectors

If you are feeling brave and have access to DOS you can look at the 
boot sector by using the MS-DOS Debug utility. It goes without saying 
to use an old floppy in case of any accidents.

I used a "BIT" editor program, "Norton Utilities". It would read a 
normal boot sector and then I inserted the Pianosoft disk and copied 
the boot sector across.

Hope this helps.
