Drive has no mount point and other drives are read only.

[kdeuser]

Hi ,

I just fixed the problem with nvidia drivers which seems to have scrambled the hard drives.

First, one drive does n`t mount as it lacks a mount point and the other drives are read only.

Never had to mount the drives before as Reelbox ( my htpc ) did this for me.

A copy of fstab file :



A copy of gparted showing the 3tb unmounted drive :



Basically just want to write to the drives again.

Thanks for your help.

Regretfully your links don't open up.
Admin is notified.

This is because these files do not have the allowed file extensions (.doc, .txt, etc ) as described in the attachment management area.

it is easy enough to paste the text in these files into a post, these are not large files

What's the output of lsblk?

[kdeuser]

Here`s the lsblk output :



Does not look good.

[SteveRiley]

The lsblk utility is part the package util-linux. That should be present on nearly every Ubuntu system. Perhaps it's missing from yours. Install it:

sudo apt-get install util-linux

Also, kdesudo is used only when running graphical applications with elevation. Use sudo for text-mode commands. Oh, and a gentle reminder -- when working through troubleshooting steps, try not to second-guess. Randomly adding sudo to a command could have unintended side effects.

[kdeuser]

Ok , thanks for that advice .

The print from `util-linux` :

[SteveRiley]

Hm. The package is installed...I don't understand why the command isn't working for you.

What's the output of these two commands:

dpkg -L util-linux | grep ls

which lsblk

[kdeuser]

dpkg -L util-linux | grep ls

which lsblk

[kdeuser]

Just out of curiosity I ran
teunis@W520:~$ which lsblk
/bin/lsblk
No surprise.

teunis@W520:~$ dpkg -L util-linux | grep lsblk
/bin/lsblk
/usr/share/bash-completion/completions/lsblk
/usr/share/man/man8/lsblk.8.gz

Is there a fix or do i have to buy another drive and load data off the unmountable one .

That`s expensive for me at the moment .

Guess free computing comes at a price - lol .

P. S. - Is there a way i could write to the other drives ?

[SteveRiley]

I'm trying to figure out what disk devices your system sees when it boots normally. The GParted output isn't too helpful, as the device node names aren't guaranteed to match.

The fact that your lsblk command is missing is confusing. What's the output of these commands? They'll help me understand a bit more about what's installed on your computer.

lsb_release -a

uname -a

apt-cache policy util-linux

And also these commands? They'll provide similar information about your disks:

sudo fdisk -l

cat /proc/mounts

ll -R /dev/disk

[kdeuser]

Requested readouts :

reel@ReelBox:~$ sudo fdisk -l

Oh wow, you're on 10.04? That's four and a half years old. No wonder you don't have lsblk -- it's not part of the util-linux package in that release.

And the output of fdisk tells me that three of your drives -- sdb, sdc, and sdd -- have GPT rather than MBR partitioning schemes. We'll have to use a different tool to see the partitions. First, install it:

sudo apt-get install gdisk

If Apt tells you it's already installed, that's fine.

Now, what's the output of:

sudo gdisk -l /dev/sdb

sudo gdisk -l /dev/sdc

sudo gdisk -l /dev/sdd

BTW, you really should consider rebuilding that machine with the current version of Kubuntu. All support for 10.04 ceases in April 2015.

[kdeuser]

Gdisk is installed and yes , i know the pc needs upgrading however, being a shoe horned version of kubuntu the machine would fail to work.

Each of those drives has a single partition. And none of them are in your fstab -- thats why they aren't mounting. Let's create some mount points, and then mount those drives to the points and take a look.

First the mount points:

sudo mkdir /mnt/sdb /mnt/sdc /mnt/sdd

Now mount them:

sudo mount /dev/sdb /mnt/sdb

sudo mount /dev/sdc /mnt/sdc

sudo mount /dev/sdd /mnt/sdd

Now, you should be able to open Dolphin and explore these drives. Can you?

[kdeuser]

reel@ReelBox:~$ sudo mkdir /mnt/sdb /mnt/sdc /mnt/sdd
[sudo] password for reel: 
reel@ReelBox:~$ sudo mount /dev/sdb /mnt/sdb
mount: /dev/sdb already mounted or /mnt/sdb busy
reel@ReelBox:~$ sudo mount /dev/sdc /mnt/sdc
mount: you must specify the filesystem type
reel@ReelBox:~$ sudo mount /dev/sdd /mnt/sdd
mount: /dev/sdd already mounted or /mnt/sdd busy
reel@ReelBox:~$

Drives sdb and sdd are fine just can not write to them and sdc still gives error.
