Hello everyone,
I’m running Ubuntu 24.04 on a Toshiba Satellite L840D laptop. This laptop came with an HDD, but about 3 years ago I upgraded it with a 2.5" SSD. Over the past couple of weeks, the laptop has sometimes had trouble booting. Earlier today it was worse than ever. It gets past the BIOS, but Ubuntu fails to load, either displaying a variety of error messages or just showing a blank screen.
I removed the SSD from the computer and connected it using an enclosure to a different computer. All of the files seem to be intact, and I could still copy them off of it for backup.
After some Internet searching, I ran smartmontools on the drive while in the enclosure. Here are the results:

I put the HDD back in the computer (it has 22.04 - the upgrade to 24.04 was obviously done after I installed the SSD) and it worked just fine.
Anyone know what might be going on with the SSD and if it can be fixed?
Welcome to Ubuntu Discourse 
Have you tried running fsck on the SSD?
I was about to point to a number of past ubuntuforums threads (the old forum) where there are very helpful discussions on life expectancy of SSD’s. Even new SSD’s. Notably from expert TheFu (who I understand has not joined this discourse forum).
But for some reason, I find that searching is disabled in the old forum. Don’t know why. But I will investigate if only for my own interest in digging through archives.
There is a wealth of gems buried away in the old forum. SSD’s can fail sooner than expected.
Updates:
I ran fsck on the SSD, and it fixed a large number of errors. I reinstalled it in the laptop, and it still failed to boot, but it did perform better than before. Instead of a blank screen, the Ubuntu logo with the scrolling dots underneath briefly appeared, followed by the error message
[FAILED] failed to start gdm.service
and once also with
[FAILED] failed to start rsyslog.service
Since the GRUB screen appeared (it typically doesn’t), I tried the four different kernels presented (6.8.0-40, 6.5.0-45, 6.2.0-39, and 5.19.0-50). I still had no problems copying data to and from the SSD while it was connected to a different computer, so I think the drive is actually okay.
Is there anything else I could try? Maybe reinstall Ubuntu if needed?
I will also keep looking around the old forums, just in case.
Before considering a reinstall, perhaps try this first:
Boot into Recovery Mode from the GRUB menu and choose the Advanced options >> recovery mode for the most recent kernel.
From root shell:
journalctl -xb
Look for red or error entries, especially related to gdm, graphics drivers, or anything mentioning Xorg.
Are you using an Nvidia graphics card?
At each stage, post back any errors you get.
Actually, you might want to follow this process for the most recent plus one more recent one.
Doing a (comprehensive) test of the SSD wont hurt. Perhaps you can use bios for testing.
Or you can use sudo smartctl -t short /dev/nvme0. Replace nvme0 with your drive. If this passes you can try a long test.
Don’t quote me on this … BUT some say that this field is here (above) one looks at for life left on a SSD .
Using their quotes 100 = 100% life using that the 13 would indicate 13% life left.
(problem is each vendor uses a differing value so it’s not actually accurate, such as samsung vs kingston etc)
HOWEVER…(here is where you can quote me on)
There is a trick to refresh (rebuild) a SSD Which sometimes works (personal experience is about 90+% success rate).
power the laptop down.
connect only the power side of the drive , do not connect the data side of the connections.
(you may have to remove the drive completely and use a desktop or external powersupply as most laptop use a 1 piece connector for data and power)
Most will advise to boot into bios saying it will prevent data access to the drive. But honestly that is not required as if only power is connected and the data side is not connected the bios doesn’t know the drive is present.
Inside the SSD this power only connection will trigger a re-build of the cells within the firmware of the SSD.
Let this run in this state for 2 plus hours (usually 1 hour works but longer is better as in this state one cannot monitor the rebuild process of the cells so longer is better. Personally I’ve never went beyond three hours for the process).
reconnect the drive properly then you could attempt a reboot to see or dive directly into a recovery process.
The above method may or may not fix the issue… but it will conduct a self assessment and initiate a rebuild of the cells.
Used in conjunction with a Recovery Boot (usb/cd) is usually successful
using the procedure outlined by @rubi1200 works pretty well once the cells have been rebuilt.

More updates:
Short and long smartctl tests were completed without error.
This computer has an integrated Radeon graphics card (and AMD CPU).
I ran fsck again on the drive (after the most important step - getting my morning coffee!) and I’m getting a bad magic number in superblock error.
Please post the errors you encounter so we can review them.
Even a screenshot is alright if you are not able to copy and paste from the terminal for some reason.
Okay, this is all from Ubuntu 24.04 running on a live USB (since if it comes to a reinstall I would need that anyway):
The SSD is /dev/sda, and has four partitions (this info is from the Disks program):
/dev/sda1: 1.0 MB, BIOS Boot
/dev/sda2: 538 MB FAT, EFI System
/dev/sda3: 500 GB ext4
/dev/sda: 1.1 MB unallocated
That looks standard to me, but I’m posting it anyway in case anyone wants to refer to it.
Running fsck on each of these partitions gives these results:
ubuntu@ubuntu:~$ sudo fsck /dev/sda1

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or

I really don’t know why it says lifetime of 169 hours for a drive I’ve been using for almost 3 years.
Your partitions are not really standard for a modern OS on a recent computer.
Do you know if your Toshiba Satellite L840D laptop is UEFI compatible?
It doesn’t have UEFI, so I do not believe it is compatible. I just went with the defaults when I installed Ubuntu. It was a clean install on an empty drive.
It’s not a recent computer either. I bought it in 2012 (which is why it had an HDD at first).
A laptop from 2012 would perform better with a lighter flavour from the Ubuntu family such as Lubuntu or Xubuntu.
Secondly, for pre-UEFI PCs, there have been occasions where the OS may need to be installed on one partition only i.e. without the BIOS Boot partition ( yours is sda1)
Have a look at this example (post 6) https://discourse.ubuntu.com/t/operation-system-not-found-dell-inspiron-n4110/51073/5
Lastly, ensure that you have backed up your personal data.

I’ve decided I’m going to reinstall Ubuntu and see if that fixes it. I will be sure to set up the partitions that way.
On the other hand, it did work without issue for almost three years. Perhaps something happened recently that caused problems.
Three years ago, your PC was 9 years old
Your Toshiba is now 12 years old and modern software probably needs more resources.
Or possibly, the motherboard is showing signs of wear and tear?
Have you eliminated the option of a lighter Ubuntu family flavour?
By the way, how much RAM in your device?
I went ahead with the reinstall, and was careful with the partitions. For now, it’s working normally again.
Of course, I understand that the computer is 12 years old and could be close to the end of its life. I am sticking with regular Ubuntu, because I have never had any problems with performance. It has a quad-core CPU and 8 GB of RAM. I only use this computer for light tasks at this point anyway.
