Salut,

hier soir j'ai eu une alerte smartctl concernant mon disque dur.

Je vous mets ci-dessous le résultat de smartctl -a /dev/sda et un
extrait inquiétant :

SMART overall-health self-assessment test result: FAILED!
Drive failure expected in less than 24 hours. SAVE ALL DATA.

233 Media_Wearout_Indicator 0x0013 001 001 001 Pre-fail Always FAILING_NOW 146800

Je vais relancer un test mais a priori ça ne sent pas bon. Même si je ne
sais pas vraiment interprété le résultat de smartctl. Par sécurité je
vais commander un disque.

Sur

https://serverfault.com/questions/316150/how-to-determine-number-of-write-cycles-or-expected-life-for-ssd-under-linux

That still doesn't guarantee when/if you'll see failures or
   errors. Drive could fail tomorrow, could fail in three years.

Selon smartctl mon disque est SATA Version is: SATA 3.1, 6.0 Gb/s (current: 6.0 Gb/s)
C'est un 250 Go, je prendrais bien une capacité un peu supérieure (je
suis à 90% d'utilisation disque).

LDLC propose https://www.ldlc.com/informatique/pieces-informatique/disque-ssd/c4698/+fv63-10416+fv32-10948.html

Des conseils/suggestions par rapport à la liste LDLC ?

Un changement de disque M.2 est facile à faire ? Il faut un outillage
spécifique ?
