Started getting input/output error and the SSD is no longer working

Suddenly started getting input/output errors on running commands in terminal. Restarted, now the disk isnt recognized and wont mount leading to “timeout waiting for disk …” error on systemd. Hasn’t even been a year since I got the new SSD.

Attaching fsck and fdisk ouptut. On IRC told that it could be hardware failure and can reach out to WD and see if they can recover. I'd like to see if there's something I can do in the meantime and if it is easily fixable. I need the data on it and going to WD and recovering data if any is going to take weeks.

[meet@meet-laptop dev]$ sudo fdisk -l /dev/sda
Disk /dev/sda: 16 KiB, 16384 bytes, 32 sectors
Disk model: Sandisk Milpitas
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

[meet@meet-laptop dev]$ sudo fsck /dev/sda
fsck from util-linux 2.36
e2fsck 1.45.6 (20-Mar-2020)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sda

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
    e2fsck -b 32768 <device>

Re: Started getting input/output error and the SSD is no longer working

You run fsck on a filesystem level, so passing the entire blockdevice is wrong, you'd pass a partition.

What you actually should pass the entire device to before the fsck  is a smartctl command: https://wiki.archlinux.org/index.php/S. … Run_a_test

Run a long test, wait for the mentioned time to pass and post the output of

sudo smartctl -a /dev/sda

Re: Started getting input/output error and the SSD is no longer working

I see, the partitions aren't visible.

[meet@meet-laptop flamy]$ ls /dev/sda*
/dev/sda

The long test command failed

[meet@meet-laptop flamy]$ sudo smartctl -t long /dev/sda

The later command output even though the earlier one failed if helpful

Re: Started getting input/output error and the SSD is no longer working

Check https://wiki.archlinux.org/index.php/S. … .#smartctl in that case and enable smart if possible, if that's not possible then I'd choose another brand as that's pretty basic diagnostic functionality that's lacking here...

Re: Started getting input/output error and the SSD is no longer working

This is from WD. I believe lack of smartctl not able to get the info maybe the same problem?

[meet@meet-laptop flamy]$ sudo smartctl --info /dev/sda

Re: Started getting input/output error and the SSD is no longer working

Potentially, user capacity 16KB really reads like the HW controller is hosed.

If possible try another SATA cable/port or so, maybe it's just a cable issue

Re: Started getting input/output error and the SSD is no longer working

Can that happen out of blue without any reason? And what can be done about it? Anyway to get the data back?

It isn't a cable issue because I tried connecting another HDD with the same cable and it and its partitions all were detected correctly.

Re: Started getting input/output error and the SSD is no longer working

I also suspect that only WD can really help you here. Unless it's a kernel bug? Any other operating systems to test?

Not really, got different version of kernel, but that's it. However, it was working fine until now, so unlikely it could be a kernel bug..?

google "Sandisk Milpitas SSD" … this device seems to have this problem more often :-(

Re: Started getting input/output error and the SSD is no longer working

SSDs are finitely durable storage and will fail hard and for most users irrecoverably when their time comes. I hope you have backups -- in that case I'd ddrescue everything that's left readable, discard this faulty device and move on. Getting the data off this thing is first priority if not already. If it's under warranty get it replaced.

Sadly no backups and I had some idea with the SSD failures however did not expect this soon. It hasn't been a year yet and failing while still under warranty.

If ddrescue can get me the data, it'd be great!

ddrescue also only rescues the 16kb that kernel is able to report is the size of the device
