    Probably your SSD does not support S.M.A.R.T. – mook765 Apr 28 '17 at 8:06
  • The problem is the USB adapter. – user589808 Apr 28 '17 at 15:21

From How can I check the SMART status of a SSD or HDD on current versions of Ubuntu 14.04 through 18.10?:

SMART option greyed out

This can happen with NVMe SSD's. You need to install NVMe SSD specific SMART tools:

sudo apt install nvme-cli

Then run the program to report health of drive:

$ sudo nvme smart-log /dev/nvme0
Smart Log for NVME device:nvme0 namespace-id:ffffffff
critical_warning                    : 0
temperature                         : 40 C
available_spare                     : 100%
available_spare_threshold           : 10%
percentage_used                     : 0%
data_units_read                     : 28,167,888
data_units_written                  : 19,397,424
host_read_commands                  : 561,183,142
host_write_commands                 : 171,788,833
controller_busy_time                : 1,354
power_cycles                        : 2,385
power_on_hours                      : 1,363
unsafe_shutdowns                    : 133
media_errors                        : 0
num_err_log_entries                 : 608
Warning Temperature Time            : 0
Critical Composite Temperature Time : 0
Temperature Sensor 1                : 40 C
Temperature Sensor 2                : 51 C

The most important data point is:

percentage_used                     : 0%

When it hits 100% it is time worry about replacing your drive. That said this drive is two years old and still at 0%

Not all USB adapters support SMART. I have 2: one of them supports it, the other one not. Both of them USB3

NVME Support was added to smartmontools starting from version 6.5. Please note, that currently NVMe support is considered as experimental.

You can check your current version with the command apt-cache policy smartmontools

The latest version for 16.04 LTS in the repositories ATM is 6.4+svn4214-1 which doesn't have this feature. However it appears that the versions available for artful, bionic and cosmic do have it. Newer packages can often be found here. Alternatively, you can install from source or try a daily build.

For more details on the current status of NVMe support in smartmontools check the wiki.

Info on USB SMART support in smartmontools can be found here.

In my computer I have

  • an nvme drive

  • Lubuntu 18.04.x LTS with

    • Disks version 3.28.3 - the "S.M.A.R.T. data self test" is greyed out.

    • smartmontools version 6.5+svn4324-1 - the "SMART overall-health self-assessment test" works.

So I suggest that you install the package smartmontools and use the tool smartctl.

    OP is on Ubuntu 16.04 (at time of writing question in 2017). Will the new version install on an old LTS? Also is there a link to product description with screenshots? – WinEunuuchs2Unix Nov 25 '19 at 12:49
  • @WinEunuuchs2Unix, Good catch about the version :-) I am not sure if the new version installs on an old LTS. But the test can be done from a newer Ubuntu version running live (without installing nvme-cli). Still Disks has it greyed out for nvme. -- What product description are you asking for (the nvme or the connecting chain PCI-e card, motherboard)? – sudodus Nov 25 '19 at 13:00
