Documentation problem with the UG - POSIX devices?

Documentation problem with the UG - POSIX devices?

[Buchbinder, Barry (NIH/NIAID) [E]]

https://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-posixdevices

In the paragraph starting "Block devices are accessible ..."

"... or the first partition on the third harddisk is \device\harddisk2\partition1."

Shouldn't partition1 be the second partition, not the first?

Best wishes,

No.  partition0 is a symlink pointing to DR0, which in turn is the
entire physical disk.  As admin:

  $ ls -l /proc/sys/Device/Harddisk0 | grep DR0
  brwxrwx--x 1 Administrators SYSTEM 0, 250 Nov 11 17:32 DR0
  lr--r--r-- 1 Administrators SYSTEM      0 Nov 11 17:32 Partition0 -> /proc/sys/Device/Harddisk0/DR0
  $ ls -l /proc/sys/GLOBAL\?\? | grep DR0
  lr--r--r-- 1 Administrators SYSTEM        0 Nov 11 17:32 Disk{2b5b33fa-7185-944d-98ae-4ff14c0e5391} -> /proc/sys/Device/Harddisk0/DR0
  lr--r--r-- 1 Administrators SYSTEM        0 Nov 11 17:32 PhysicalDrive0 -> /proc/sys/Device/Harddisk0/DR0

So the real partitioning starts with partition1, since partition0 is a
link to the physical disk as a whole.
