Thank you,
URLs posted yesterday explicitly stated that the Ensoniq Mirage format
was 10 512 byte sectors.

What you just posted matches what I had encountered.  But I had only one
sample diskette, that didn't have enough content to analyze the file
system; and the owner of it died before he got around to giving me
another.

I hope that Allison is reading this thread.
Not for the 8 foot disk in the subject line,
but for the mixed sector sizes, combined with a sector numbered ZERO.
