Cannot access my second internal HDD 1TB on latest Ubuntu

Question

I just installed Latest Ubuntu x64 from USB. All was OK. Installed on my Win 8.1 with option "replace your current Windows with Ubuntu". (Not dual boot with Windows,) My question: How to get in to my HDD to store files? P.S. I am new to Ubuntu. Here is some info:

I really do not understand yet what it means. Just curious about:

   21.5GB  1000GB  979GB   ntfs         primary  hidden, msftdata

I have very important files on my 1TB HDD, but I am able to format it. No function to mount or whatsoever to do with that HDD. I want to save it if there is a possibility of doing that.

Please help.

Since this is an internal HDD, we can add an entry to /etc/fstab to make Ubuntu mount it on boot every time. First, pick a directory you want to mount it on (like /home/marius/internal, where marius is your username. Make sure the directory exists (make a new one if you need to). Then, do:

cat <<EOF | sudo tee -a /etc/fstab
/dev/sdb1 /home/marius/internal ntfs-3g rw,exec,uid=$(id -u),gid=$(id -u),umask=022 0 0
EOF

This will add an entry to /etc/fstab giving you proper read/write permissions. Then, do:

sudo umount /dev/sdb1
sudo mount /dev/sdb1

The first command will undo the previous mount, then the second will mount it with the new settings.

If it is a new hard disk, you can format it afresh, and start using it. Open the Disks program, select your new hard disk from the right hand pane, click on the gear icon in the top right corner, and choose Format.

Use the default option (both GPT and MBR work fine). Once it creates a new partition table, click on the +, choose a size. For the type, if you wish to use it on Windows as well, select "Compatible with most systems (NTFS)" instead of the default (ext4). Give a nice label. Click on the play icon to mount it. (Or on the corresponding icon in the file browser.)

I'm sorry I can't give you more information about the hidden RAID part.
