Mount issues

Before messing with your mount points, I suggest saving a list of the
current mounts to a file (mount > file.txt; mount -p >> file.txt).

You can run mount.exe from the MSDOS prompt.  That allows you to umount all
the user mount points (umount -U) before you replace them with system mount
points (mount -b -s <msdospath> <posixpath>).  You should probably exit all
Cygwin programs first.

You don't want to explicitly mount anything under /cygdrive.  /cygdrive is a
convenience mount point for any MSDOS drive letters that you haven't mounted
explicitly.  You remove and establish the cygdrive prefix using special
options to umount (umount -u -c) and mount (mount -b -s -c <posixpath>)

Both mount and umount display a help screen if given the "-h" option.

Search the registry for 'Cygwin', but you really are better off using mount
and umount to change your mount points.
