	Well, with a block size of 1024 bytes:

	1200 blocks * 1024 bytes/block = 1228800 or ~1.23Mb.

	Taking into consideration 200 blocks worth of system info, it appears
that your system *is* writing it as a 1.44Mb floppy.

	Since you didn't say whether you made a 1.44Mb partition before you
tried to make the file system, I can only venture to guess that the system
sees it as a zero length partition, hence the error message.

	NOTE: I don't claim to know all the different flavors of Unix, but
I'm sure that your system is seeing the full 1.44Mb floppy.
