Using ",NEW" creates an image without a header. The initial size of the
image is that of a 35 track single-sided floppy.

The only information obtained from the header is the number of sides. When
no header is present, the CoCo SDC makes assumptions about the disk
geometry based on the file size. The "Disk Image Formats" page on the blog
has a table showing how the size is interpreted.
