SSD failure?

Happened turning it on a couple days ago. This was not the result of an update as I was not updating and had been on and off several times before hand. I put it in an external care and I could chroot and update with my other computer but I still get this on boot.

DDG pretty much implies the drive is likely about to be complete dead, but I thought I’d see if any of y’all have experience with this one.

Everything is backed up. Smartctl short test passes.

Samsung Evo 850 drive.

It says to run fsck manually. Did you?

What does the long test show for smartctl? It takes a bit of time.

sudo smartctl --test=long /dev/xxxx (your drive) 

I would say Y to everything:

fsck -y /dev/sdb4

For verbose:

fsck -yV

It’s several hours if I recall. I’ll try and set it up in a bit.

I think it’s probably software errors (if it passes the long test. Maybe fsck will correct that?

So, I’d be lying if I knew what that did but it worked. I watched -yV go for like 2 min straight and now it seems good.

Thank you.

The real question though, is the drive failing? Or what caused that in the first place?

You are welcome! Glad it worked!

Let’s hope it is not!
To make sure, run the smartctl test when you find time.

Run the long test and if it comes back good i would say it was a file system error. (corruption)

Show SMART Attributes. sudo smartctl -a /dev/sdb

Long test is running. 4.5 hours to go.

I guess it’s good?

SMART values indicate that the ssd is in good condition.
And it is written only < 3 TBW

I have two of those same discs. A couple of things therefore make me wonder:

I have not seen this before

=== START OF READ SMART DATA SECTION ===
SMART Status not supported: Incomplete response, ATA output registers missing

On my disks:

=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED

But according to this page it may just be a (fixed) bug:
smartmontools.org

But why does the ‘bug’ appear on your ssd and not on my?
Same disks, same OS and same firmwares…

And the second:

199 CRC_Error_Count 0x003e 099 099 000 Old_age Always - 3
235 POR_Recovery_Count 0x0012 099 099 000 Old_age Always - 90

The latter can perhaps explain the former.
POR_Recovery_Count = Unexpected Power Loss, is quite high in relation to operating hours.
And they may have caused those harmless crc errors.

Maybe it’s because it’s a laptop? Are you using yours in a desktop or laptop?

199 CRC_Error_Count         0x003e   100   100   000    Old_age   Always       -       0
235 POR_Recovery_Count      0x0012   099   099   000    Old_age   Always       -       478

Mine says 478 which I find weird cause I’m pretty sure there wasn’t some power loss every couple of days. It’s an external ssd I use for my Pi 4b server which I reboot maybe once every 2 weeks.

I’m not the only one:

Desktop.

POR Recovery Count
A count of the number of sudden power off cases. If there is a
sudden power off, the firmware must recover all of the mapping
and user data during the next power on. This is a count of the
number of times this has happened.
Samsung SSD Note

Maybe some power saving will increase the figure +1. I have no experience with Pi.
