Question 1:
I'm the administrator of my Lubuntu system. I only have one "Desktop User" account for all kids. But when ever the Desktop User tries to access or open the "Data"[NTFS partition](Drives where movies, pics, songs and other files are stored) it asks for the Administrator's password. I created the user account for all my other family members and I don't want to tell them my password.

So is it possible to allow them to access the "Data" NTFS partition without asking Administrator's password ? it says "Authentication is required to Mount (/dev/sdc7)"

Question 2:
i'm on lubuntu 14.4.0 (by the way how to check my installed lubuntu version?) and will it update from SOFTWARES & UPDATES it self or i'll always need to CLEAN FORMAT INSTALL a never version everytime?

NOTE:
please provide a screen tutorial how to fix the "Question 1" because lubuntu is my 1st linux ever. and I'm a novice user. just installed yesterday.

SOLVED Question 1:
in DISK App on NTFS Partition. i Turned On Auto Mount and then added "users" in the Text bar displaying codes. And it works now :-)
