CYGWIN_NT-5.0 KHELDAR 1.3.4(0.46/3/2) 2001-10-01 16:25 i686 unknown

Floppy access.

mount table:

D:\Documents and Settings\Administrator\desktop on /desktop type user 
(binmode)
D:\Utils\localtexmf on /localtex type system (binmode)
D:\Utils\MiKTeX on /tex type system (binmode)
D:\cygwin\bin on /usr/bin type system (binmode)
D:\cygwin\lib on /usr/lib type system (binmode)
D:\cygwin on / type system (binmode)
\\.\a: on /dev/fd0 type system (binmode)
C: on /c type system (binmode)
D: on /d type system (binmode)

dd if=/dev/fd0 of=disk1.img bs=1k count=1440

works.  I can take disk1.img to a linux box, mount it on a loop device, 
and everything is fine.  I copied a few files into the mounted image, 
unmounted, and copied the modified disk1.img back to my cygwin box.

dd if=disk1.img of=/dev/fd0 bs=1k count=1440
dd: opening '/dev/fd0': Permission denied.

This was as a normal user.  I then tried to write to the floppy in raw 
mode as Administrator. Also permission denied.

This looks like a regression to me.  After replacing the dll with the 
one from 1.3.3-2, I could write to the floppy in raw mode.

So, with the 20011001 snapshot, read in raw mode from floppy works, 
write does not.
