I need your help with this mount problem

[carmatope]

There was an error accessing "2.7 TiB Hard Drive",
the system responded:
The requested operation has failed: 
Error mounting /dev/sdd2 at /media/cm/780a98da-4ccf-46f8-a53b-f0f86181df7d:

'exited with non-zero exit status 32: 
mount: wrong fs type, bad option, bad superblock on /dev/sdd2,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try dmesg | tail or so.

As you can see reinstalling it's a major loss of information.


Things you must know:
It was a guided installation
Don't has partition /home


When I've tried to repair the installation from a live usb
I've noticed there is an option to install without formatting.


My question is:
Can I reinstall without losing it all or there is another solution?

Error mounting /dev/sdd2 at /media/cm/780a98da-4ccf-46f8-a53b-f0f86181df7d:

There is no /dev/sdd. I only see /dev/sda, with three partitions, and /dev/sdb with one.

There is no /dev/sdd. I only see /dev/sda, with three partitions, and /dev/sdb with one.

So what's the solution? I can't access my hard drive at all.

[Bashing-om]

carmatope; well,

We now know that the ubuntu install is on sda2; let's take a look and see what is set to mount.
From the liveUSB;

sudo mkdir /mnt/look/
sudo mount /dev/sda2 /mnt/look/

and now show us the output of terminal command:

cat /mnt/look/etc/fstab

Once done, back out of the mount operation to preclude file system corruption. You mounted it and the system does expect you to UN-mount.

sudo umount  /dev/sda2

see where we stand in that process
