From the Western Digital WD1770/1772 Floppy Disk Controller/Formatter Manual:
Page 5 (p.1398, Atari Developers Documentation):
_____________
"...Writing is inhibited when the Write Protect input is a logic low,
in which case any Write command is immediately terminated, an
interrupt is generated and the Write Protect status bit is set."
This means that the write protection is checked AND enforced by the
disk controller _hardware_. The software has no choice in the matter.
Unless Western Digital is _lying_, you can't write to a write protected
disk no matter how hard you try.

Unless we see a program that contradicts the manual, can we consider the
case closed? Unsupported arguments are _heresay_...
Someone mentioned that NeoDesk dodges the write protection. Anyone
want to testify to this?!?!? Will the author of NeoDesk confirm/deny?
