Script to quickly scan the S.M.A.R.T. health status of all your hard drive devices in Linux (at least all the ones from /dev/sda to /dev/sdzz). You need smartctl installed on your system for this script to work, and your hard drives need to have S.M.A.R.T. capabilities (they probably do).

smartcheck.sh

#!/bin/bash

# install the smartctl package first! (apt-get install smartctl)

if sudo true
then
   true
else
   echo 'Root privileges required'

   exit 1
fi

for drive in /dev/sd[a-z] /dev/sd[a-z][a-z]
do
   if [[ ! -e $drive ]]; then continue ; fi

   echo -n "$drive "

   smart=$(
      sudo smartctl -H $drive 2>/dev/null |

      grep '^SMART overall' |

      awk '{ print $6 }'
   )

   [[ "$smart" == "" ]] && smart='unavailable'

   echo "$smart"

done

this is awesome, thank you!

I'm glad it's helpful to you

Switching to this will better support SAS disks:

      sudo smartctl -H $drive 2>/dev/null |
      grep '^SMART overall\|^SMART Health Status' |
      rev | cut -d ' ' -f1 | rev

work gr8

Thanks, I'm so glad to hear this is useful to you.

How can this code be modified to exclude drives marked as "unavailable?

This isn't a situation with which I'm personally familiar, and since I'm unable to replicate it on my own system, I don't think I can provide you with a solution at this time.

Modify line 14 to include nvme:
for drive in /dev/sd[a-z] /dev/sd[a-z][a-z] /dev/nvme[0-9]n[0-9]

That's a great enhancement, thank you, ***@***.**** !

If anyone is interested, I ended up taking this a bit further. It lists all disks, supports outputting to JSON (I have a crontab job that sends the results to node-red and does alerting), but also supports showing the remaining life of a lot of SSDs (mostly enterprise):

There is also a ListDisks script that shows a lot of details in one quick script:

thank BloodBlight

Why not just use lsblk

for disk in $(lsblk --json | jq -r '.blockdevices[].name'); do smartctl --all /dev/${disk}; don

That option didn't exist at the time I wrote this code. Maybe it's time for an update? Send a pull request, my friend 😊
