sudo fdisk -l made a list of all existing hard disks on my computer and df -h listed the hard disks use on my computer. I have two hard disks (i.e. dev/sdb and dev/sdc) with 1.8 TB of capacity, and I need them to be used on my computer.

How could I activate those hard disks so that I can use them? With not uninstalling anything if possible?

I didn't know it could be an issue. Ok, I did it on unix.stackexchange.com. — Jeremie, Apr 15 '18 at 20:38
You may be confused. "Drivers" don't pertain to the disk information that you show. Please tell us what problem that you're trying to solve so that we can help. — heynnema, Apr 15 '18 at 21:03
@heynnema I need to activate my two hard disks dev/sdb and dev/sdc without uninstalling anything. — Jeremie, Apr 15 '18 at 21:15
I think by activate, you mount. At the command line try: sudo mount /dev/sdb1 /mnt and see if you can see the volume. E.g. if the mount command is successful, try ls /mnt. You might also want to post the contents of /etc/fstab? In particular, let's see if the installer write config lines for these volumes. — Martin W, Apr 15 '18 at 21:16
Ok, that looks good. It looks like @heynnema has already pushed the answer I would have given you. Use instructions in the answer below. — Martin W, Apr 15 '18 at 21:30

To mount the sdb and sdc disks at boot time...

In terminal...

sudo blkid # show UUID's

note the UUID's for sdb and sdc.

sudo cp /etc/fstab /etc/fstab.bck # to create a backup

sudo pico /etc/fstab # start the editor

add three lines that look something like this...

# ntfs disks

UUID=8E3A804C3A8032EF /media/infinity/Document_2 ntfs-3g defaults 0 0

UUID=to_be_determined /media/infinity/Document_3 ntfs-3g defaults 0 0

change the UUID to the values found in blkid
change the your_username (to infinity)
change the "Document_2" and "Document_3" names, if needbe

control+o # to save edits

return # to confirm filename

control+x # to exit the editor

sudo mount -a # to mount the disks

your_username is shown in the terminal prompt, before the @... probably something like "jeremie". sdb_Data and sdc_Data are the volume names that you want displayed... like "Movies" and "Development". – heynnema Apr 15 '18 at 21:28
Yes, of course. – heynnema Apr 15 '18 at 21:39
I will show you my development in my question if it doesn't work. Thanks! – Jeremie Apr 15 '18 at 21:40
No. Use 8E3A804C3A8032EF, which is the UUID for sdb, and you've changed sdc since your question, so you'll need to redo it like you originally did, and then it'll show a proper UUID. You'll want to change the partition label from "New Volume" to something more representative. – heynnema Apr 15 '18 at 21:49
You originally showed sdb and sdc as ntfs volumes. Now sdc shows as a raid volume. If you used gparted to init the drives and create new partitions, (assuming that you have no data there) repeat that process on both drives, and name the ntfs partitions Document_2 and Document_3. Use GUID partition tables if the drives are >2GB. – heynnema Apr 15 '18 at 21:55
As I mentioned, somehow you've inited/used sdc as a RAID member, so to mount it like sdb, you'll have to use gparted to reinit it and create a new ntfs partition. – heynnema Apr 15 '18 at 22:10
Start gparted. Create a new GUID device partition table on /dev/sdc. Then create a new ntfs partition named Document_3. – heynnema Apr 15 '18 at 22:13
Follow my last comment. – heynnema Apr 15 '18 at 22:18
I have modified my question so that you can see the output related to df -h. It did not work if I want to replace /media/infinity/Document_2. I wish to increase the memory of /home/infinity/.Private from 152G to 151G + 1.9T + 1.9 = 3.951T. Is it possible? What do you suggest? – Jeremie Apr 15 '18 at 23:01
@Jeremie if your final goal was to make your /.Private larger by adding two 2TB disks to it, you should have said so earlier, 'cause that requires a different approach. What does making /.Private=3.95TB any different than using the disks mounted separately as you're doing now. If you still want to do that, I'd recommend using LVM disks... but that's a whole new question. – heynnema Apr 16 '18 at 03:23
Ok, I will create a new question soon and inform you about it. Thanks again for you question. – Jeremie Apr 16 '18 at 11:06
