Sounds like you need a copy of 'Beneath Apple DOS'.

There is source code for DOS that does all of that, Format and lay out 
sectors, write sectors.  No reason you'd need to reinvent the wheel, 
just move some tread around. :)

I think there is a BAD online somewhere.  Barring that I'd sell you a 
well used one for face value...

Of course I'd rather use the Locksmith Fast Copy write routine myself. 
But then I'm not writing anything and I don't exactly know how to 
extract it.  :)

Thankx,
