    I tried to contact support 3 times and after submitting I kept getting an error from the web page so decided to get support here.

    I got this error so ran a check

    
SMART Disk monitor:

Device: /dev/nvme0, Critical Warning (0x04): Reliability

Seems like the results are say its really new and is failing prematurely.
I’m not sure if i need to get warranty through framework or directly from western digital?
Any guidance is apprecated.

Seems like it can’t read some sectors, at that low tbw it hopefully is just a fluke and not actual degradation.

It is possible if you wipe (trim) and rewrite it it self-heals, it at least claims to still have spare available. With the current ssd prices that is likely at least worth a try.

yeah, i never had to wipe/rewrite, what should i look up for a guide? It is under warranty so i should be able to get it covered.

If you can get it replaced under warranty that is the better option.

Step 0: Coppy the contents of the drive somewhere else (unless you don’t care about what’s on the drive then you can just wipe it).

Also check the smart error count before you do the next steps.

Then boot some form of linux off a different drive (usb live system works just fine).

Find out what your drive is called, I am asuming /dev/nvme0n1 for the rest of these, replace those if it turns out to be something else.

Step 1: Tell the drive nothing on it matters anymore

sudo blkdiscard -f /dev/nvme0n1

Step 2: fill the drive (so there is something to actually try and read in the next step)

sudo dd if=/dev/zero of=/dev/nvme0n1 bs=1M status=progress

Step 3: do a full read of the drive (to see if it still has issues reading some blocks or it cleanly replaced them)

sudo dd if=/dev/nvme0n1 of=/dev/null bs=1M status=progress

Now you can recheck your smart stats, if the error count has not increased the drive has likely recovered and can probably still be used.

Just happened to notice looking back at the stats posted one of them says:

Unsafe shutdowns 123

Power cycles in the 300’s range.

Makes me wonder what triggers this “unsafe shutdown” condition according to the drive. Does anyone know?

On an old mechanical HDD a long time ago you manually “parked” the heads before killing power to the drive. Later it was an automatic thing triggered at loss of power.
