Cannot mount some hard drives

[Daba]

I cannot mount two hard drives, my most important ones!

I have three internal hard drives, one for the main OS (currently openSUSE 13.1) and two for video. I have installed CentOS 7 with KDE on an external USB 3.0 HDD, as I usually do for testing distros and his is the first distro that has shown this behaviour.

I select the drive I want in Dolphin and get the authorisation box, enter the root password and get this message:
An error occurred while accessing 'Pre NLE', the system responded: The requested operation has failed: Error mounting /dev/sda1 at /run/media/dave/Pre NLE: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda1" "/run/media/dave/Pre NLE"' exited with non-zero exit status 32: mount: unknown filesystem type 'ntfs'

I would much appreciate any solution you can offer.

mount: unknown filesystem type 'ntfs'

CentOS does not have support for NTFS filesystems out of the box. You would need to install the ntfs-3g packages from the EPEL repository first. You can use yum --enablerepo=extras install epel-release to make EPEL available if it's not currently installed and then yum install ntfs-3g

If your main OS is OpenSuSE and you are experimenting with other Linux distros, why do you have any Windows (NTFS) filesystems?

Cracked it! Thanks Trevor.

That's an easy one for once, Martin. I started the editing system I use when I was still on Windies, it's a legacy of those days.
