OK, I lied ;-).  I did some more investigation, including a disassembly of the 
TOS 3 & TOS 4 ROMs.  I assume TOS 2 is the same in this area; I used TOS3/TOS4 
because I had them handy.

I still believe there is a Hatari problem, but it is hidden with the TOS ROMs 
because they do not check the DMA status register after a floppy write.  Hatari 
1.7.x sets the DMA error bit (i.e. sets bit 0 to 0), which EmuTOS reports as an 
error.  For *writes*, TOS doesn't check this bit, although it does so for 
reads.
