Format, if it can run, handles that automatically, always has.  And 
rbf.mn can handle it since I put that stuff back in and fixed one bug 
after Darling took it out in one of his so-called "Christmas" presents. 
More like sabotage IMNSHO. Maybe he found the bug and rather than fixing 
it, a 1 byte fix, he took it all out.  Whatever.

My 1st hd has a bit over 400 megs formatted for os9, leaving room for 
nearly 1500 vdisks, runs a 4 sector cluster. My 2nd hd is also a 
1Gigger, runs a 16 sector cluster with zero problems. All formatted 
before format started puking on my system. I'm out of system ram now, 
nitros9 eats it like M&M's. One could probably fix an empty disk with 
dEd but it would be tricky. I did it to floppies while testing that 
rbf.mn for nitros9 decades ago. If I ever get this working, format will 
be the next project I'll attack, as make it allocate its own 8k buffer 
for workspace. Its  not that hard, I do it for a ramdisk up to 1.7 megs 
in myram.  And when you don't need the ramdisk, deiniz it and get every 
every byte back for other uses. No reboot required.  I like to write 
stuff that Just Works.  In fact Allen, if you can find a copy of the 
original, and commented src for format, that could be done 2 or 3 months 
quicker.
