Gene, if that's the case, I can find nothing wrong with the disk image other than it is one byte short. I'm wondoring if it may be a DMK formatted image which is completely different from all other formats in that it has the "in between: track data and such to match a reak disk. Anyway, I have about 4 disks that were in a zip that contain some level 3 stuff that all have the same problem. Nothing will load them. I've looked at them with a hex editor and the LSN0 seems to be intact when compared to a working disk as is the root directory.
I may try to get Keil's emulator up an running and see if it will load them... or maybe Jeff's emulator.

And Gene did reply:

Nope, if it was zero padded, the assembler did it.  Formatted os9 disks 
are filled with $e5e5e5's until they have been written to once.  That was 
true in 1985 and its still true.
