The binary files will only work if they are not on tracks above 34. It 
does not matter what size the disk is. What matters is that Disk Basic 
and RGBDOS can't handle gran numbers that exceed the 35 track limit. So 
if your disk is full and files get placed in gran numbers into the $80s 
as is the case of one of your disks, the files can't be retrieved.
