Could someone please tell me why doing the following
was not implemented:

main()
{
	int i;
	int fd;
	extern char data[];
	extern int data_len;

	fd = open("df1:", O_WRONLY);
	if (fd == -1)
		perror("df1:"), exit( 1 );

	for (i = 0; i < data_len; i += 512)
		if (write(fd, &data[i], 512) == -1)
			break;
}

I would like to be able to write raw data to the floppies with out
having to go though opening the trackdisk.device.  What would be
the problem with the trackdisk driver looking at the file
being opened ("df1:"), mark the disk as "in use", and then 
take data in using the file_offset value and byte_count to
write directly to the disk?

I can use the trackdisk.device, but it seems to be a large amount of
coding to deal with floppies without filesystems.  They are out
there.
