This Haas controller requireds that the program begin with "O" (not zero) and no letters only numbers. In one place the book says oxxxx and another oxxxxx, neither seems to work .
Is the floppy in good condition? Yes, in appearence at least
The drives on the HAAS seem very particular about the floppies they read. Try a few others. This does seem to be an issue.
How old is the drive on the HAAS? The entire mill is less then a year old.
Can you save programs or work offsets to the floppy? Never tried.
Is the drive dirty? No
Does it need to be replaced? it shouldn't at this point, of course it is man made.
Got an RS232 cable?

Been giving this a lot of thought as the drive has always given me trouble.
Thanks for the ideas, I will give another disk a try.
