The issue you see is the fact that Cygwin doesn't require a physical directory to mount as Linux and friends do. If you want to see them then you simply create a physical empty directory in the Cygwin root directory. I do find it interesting that the mount also changes the output of `ls /proc/cygdrive/` but that is a different issue. Another method to see which drive letters are available is to simply type mount at the command prompt. -- cyg Simple -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

You have to clearly understand, how Cygwin interact with other system, to avoid issues.

Undefined behavior, but only because you're using two mount entries at once. Accessing drive letters directly from inside Cygwin is often considered a grey area. Too much may happen on this border. You have to clearly understand, how Cygwin interact with other system, to avoid issues. If you want to access Windows path, recommended route lies through the use of cygpath utility to convert native paths to the Cygwin scheme. Et vice versa. -- With best regards, Andrey Repin Saturday, February 4, 2017 17:17:15 Sorry for my terrible english... -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

Is it OK to mount cygdrive on / ?
I've added an extra / mountpoint in /etc/fstab in order to be able to access C: without /cygdrive like this: none /cygdrive cygdrive binary,posix=0,user 0 0 none / cygdrive binary,posix=0,user 0 0 It seems to work, I can access the C: drive with just /c.
