The answer was found here. gksu gedit /etc/fstab Add the next line as (if you don't know your UUID do a sudo blkid) UUID=12102C02102CEB83 /media/Store ntfs-3g auto,users,permissions 0 0 Save it and close the file. If you need to make the directory, which I did sudo mkdir /media/Store Then sudo mount /media/Store Finally (whatever permissions you want to set) chmod 755 -R /media/Store And then make it your own chown -R /media/Store Yeah, that took me like 8-10 hours over 2 days to get. And "Store" is for "Storage" :-P edited Apr 13 at 12:25, Community answered Sep 9 '13 at 2:32, mvl1014 >> I tried : $ sudo blkid /dev/sda1: UUID="32d51560-aecb-48f6-b14a-adb297a0a984" TYPE="ext4" PARTUUID="5213caa8-01" /dev/sda2: UUID="165cb7f9-dc00-4f48-8b70-55b10ca5d4c7" TYPE="swap" PARTUUID="5213caa8-02" /dev/sda3: UUID="d4651fa9-d9e7-472f-a939-37159801244b" TYPE="ext4" PARTUUID="5213caa8-03" /dev/sdc1: LABEL="HOWELL_BASE" UUID="5A74BFD974BFB5DB" TYPE="ntfs" /dev/sdd1: LABEL="Lexar" UUID="7260-5B07" TYPE="vfat" PARTUUID="c3072e18-01" >> from "/home/bill/bin/Dell64 backup all.sh" HOWELL_BASE is 32d51560-aecb-48f6-b14a-adb297a0a984 $ sudo kwrite /etc/fstab >> current line is : UUID=32d51560-aecb-48f6-b14a-adb297a0a984 / ext4 rw,errors=remount-ro 0 1 >> I CAN'T change this, as it applies to the WHOLE DRIVE!
