Failed to Mount / Can't access tty /2100 detection error

Greetings Linux Wizards!

I hope someone is able to help…
I recently did an fsck on my root partition.

It completed quickly with one or two issues that I didn’t understand or note. Everything seemed fine for days.

Until last night I had not restarted the system but I got the following errors/messages… (see images)

The hdd doesn’t show up in directory when booting from USB instalation so it seems imposs to repair the root partition assuming I broke it.

Screen has also read: no operating system

Does anyone know of a way I can fix/recover my system?

Many thsnks

PS couldn’t add/embedd media/images in post,

Perhaps the automatic check fails and you need to run it “by hand”.

lsblk -f

should list all connected disk devices

of course not
prefer text (copy/paste command and it’s output)
for pictures there are online services and you can share the link here
(yes, you can post these links - just format them as text, so they are not active)

I hope you did it unmounted from live session or a different Installation.

I would not says that fsck broke it, probably the writing while repairing made it RiP. Sounds pretty much like an hardware defect.

Not needed and not whished at all. You have a terminal where you get all information and where you can copy and paste texts here within a code block (preformatted text).

export LANG=C
lsblk --fs
sudo parted -l
sudo fdisk -l
sudo blkid

Then people would get an overview of your disks and partitions.

If the broken device is listed here, then probably the root device is an HDD and has badblocks which are unknown to the file system.

Thank you Nachlese,

I just did the automatic check. I don’t see any reference to the main 300gb hard drive which I think previously read as sda or sda0

I’ve loaded a couple of screenshots of the error screens here:

Thank you megavolt,

I understood that the partition should first be unmounted before doing the fsck which I did, but I did not do it from live/usb session… so yes, as you say I think maybe writing while repairing must have RiP’d it…

Okay, thank you for the cmd prompts, which return as:

Hello @dsunni :wink:

I fixed the terminal outputs and set them into a code block (preformmated text). Please do it like that in the future. It is more readable.

If you are talking about the disk /dev/sdb, then it looks like it is dead. A hardware failure.

That indicates it:

You could check the kernel messages:

 sudo dmesg | grep "sdb"

But I don’t think that a normal user could save the data on the hard drive. I hope you have a backup, otherwise a rescue like this will be expensive with a specialist.

Hi, many thanks, yes I will have a go with that fancy formatting at some point, you are correct we were trying hard to access sdb but impossible, the plan is now to use some Linux recovery software and they try recover dat import word docx

Many thanx

By the way, while this thread is still active, can anyone advise how to disable ‘flight mode’. Since yesterday’s testing on the system I’ve been unable enable WiFi on the pc t430s which seems to be due to flight mode being on ‘permanently’. There is no response when selecting ‘off switch’,

Many thanks ds
