I've filled this bug in the KDE (https://bugs.kde.org/show_bug.cgi?id=307307) but they say to fill it upstream.

When I mount NTFS usb external drive with the KDE device notifier applet, the file system is mounted as a case sensitive one creating issues when the same hard disk is used in a Windows environment (the only reason I can see to use an NTFS partition is to share data between Linux and Windows). 
The applet should mount NTFS via lowntfs -o windows_names -o ignore_case by default or, at least, leave the user the option to select if mounting NTFS as case sensitive or case insensitive system. 
Reproducible: Always 
Steps to Reproduce: 
1. Attach an NTFS usb drive 
2. Mount it with the device manager applet 
3. Go to the mount folder and create two directories named test and Test respectively 
Actual Results: 
Both directory are created 
Expected Results: 
The second directory should not be created because, if system is case insensitive, as it is supposed to be in Windows, the directory whit the same name already exists.
