Help with adding a hard drive

[exploder]

I added a 1 TB hard drive to my desktop. Kubuntu can see it but I can not create folders or do anything with it. Please help me out with this.

What file system do you use? If it is ext4 I would think you have to open your KDE partition manager and format the drive. If it is btrfs I would think you have to open your partition manager and ask GreyGeek what to do next.

If you added the drive and didn't modify your /etc/fstab file to add the appropriate entry for it, then when you boot your PC it will be seen by the OS, but access to it will be restricted to 'root'. Open a konsole and type: sudo blkid and copy/paste the output in your reply. While in the konsole, type: cat /etc/fstab and copy/paste the output in your reply as well.

The output of the first command is.

/dev/sda1: UUID="ab74b0f2-149f-46ec-ba7e-fb5f997aef06" TYPE="ext4" PARTUUID="1c04ffa4-01"
/dev/sdb1: UUID="6b5847f1-4999-40f6-ade6-545388d3ec84" TYPE="ext4" PARTUUID="a267e6de-01

The output of the second one is,

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda1 during installation
UUID=ab74b0f2-149f-46ec-ba7e-fb5f997aef06 / ext4 errors=remount-ro 0 1
/swapfile none swap sw 0 0

As I suspected; you don't have an entry in /etc/fstab for the second HDD, and that confirms 'why' you can't (currently) access it as the non-root logged in user.

You can edit the fstab file and add the missing entry. Launch Kate (text editor) and open /etc/fstab for editing. Between the line that begins UUID= and the line that begins /swapfile insert the following:

# Next entry manually created by exploder on [the date you edited this file]
UUID=6b5847f1-4999-40f6-ade6-545388d3ec84 /mnt ext4 defaults 0 2

Save the file (you will be asked to provide your login password, as this is a root owned file). Exit Kate. Perform a logout and reboot of your PC.

Thank you! This fixed it, sudo chmod -R a+rwX /media

# Next entry manually created by exploder on [the date you edited this file]
UUID=6b5847f1-4999-40f6-ade6-545388d3ec84 /mnt ext4 defaults 0 2

I would think it would be better to make a directory in /mnt to mount the drive to instead of using the /mnt directory it's self their by monopolizing it , maybe /mnt/drive2 or /mnt/sdb1

Thank you! This fixed it, sudo chmod -R a+rwX /media

that is not a good fix , it's not a good idea to just throw global read/write on /media and whatever is in it (at the moment you ran that command)

I would think it would be better to make a directory in /mnt to mount the drive to instead of using the /mnt directory it's self their by monopolizing it , maybe /mnt/drive2 or /mnt/sdb1

To do what vinny is saying, you would open a konsole and type: sudo mkdir /mnt/sdb1 and when prompted, provide your username login password. This creates a 'permanent' sub-directory under /mnt. IF you did that, then the /etc/fstab entry I provided would have to read:

UUID=6b5847f1-4999-40f6-ade6-545388d3ec84 /mnt/sdb1 ext4 defaults 0 2

(The sub-directory name under /mnt can be anything you want it to be, but the name used can't contain any spaces.)

Alright, I did as you and Vinnie suggested. What should I do about the permissions though?

Depends on how you want to use it.

If you want to treat it like it was a subdirectory under your home account then actually create that subdirectory, change fstab to reflect it, reboot, then change its userwner to you using chown.

If you want to treat it as a root subdirectory then you already have that, and doing anything with it (adding, removing, editing files) will require the use of sudo or dolphin's root mode.

I did get it all sorted out finally. The dive is mounted automatically and the permissions are set the same as home.
