Mike, I think it depends on ICKDSF and which command is used to format the volume. Its been 20 or 30 years since the 3380 came out but IMSM the fast initialize does it differently than the full initialize. My memory is sketchy here but I *THINK* a EOF is written on each track if a fast init is used. I will defer to you on the full init. I learned of the fast init from a good friend at the WSC. I started using it and never had awn issue.
