Comment savoir si le SSD Ubuntu est corrompu / proche de la mort?

Question

La nuit dernière, lorsque j'ai redémarré mon environnement Ubuntu parce que cela semblait assez lent, il s'est bloqué sur un écran d'avertissement avec plusieurs lignes de texte (rien à faire, quelque chose à propos de radeon Invalid ROM contents). Je n'y pensais plus et je redémarrai bêtement, ce qui céda la place à ce long écran:

[ 160.053495] rc.loal[1933]: systemctl start teamviewerd.service [ 182.741532] sd 6:0:0:0: timing out command, waited 180s [ 182.741559] blk_update_request: I/O error, dev sdd, sector 0 [ 182.741575] Buffer I/O error on dev sdd, logical block 0, async page read [ 360.134840] INFO: task systemd:3622 blocked for more than 120 seconds. [ 360.134871] Tainted: G OE 4.4.0-116-generic #140-Ubuntu [ 360.134898] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message ... Above three lines duplicated several times without only slightly different output [ 504.125921] NMI watchdog: BUG: soft lockup - CPU#1 tuck for 22s! [systemd:1] ... More (but I am tired of transposing from picture)

Configuration:

Carte graphique AMD R9 390 (radeon au premier paragraphe?)
2 SSD (Windows et Ubuntu)
1 disque dur (partitionné entre les deux)

Certains de ces messages m'ont incité à commencer à rechercher si mon disque SSD Ubuntu peut être corrompu ou sur le point de mourir - est-ce que cela expliquerait pourquoi les opérations semblaient prendre plus de temps que d'habitude? Par exemple, mes fichiers (développeur) semblaient avoir plus de difficultés que d'habitude et l'ouverture de fichiers de projet prenait plus de temps que je ne m'en souviens.

À partir des recommandations en ligne, j'ai installé smartmontools et j'ai exécuté ce qui suit:

Sudo smartctl -H /dev/sda Sudo smartctl -a /dev/sda Sudo smartctl -t short /dev/sda Sudo smartctl -l selftest /dev/sda

C'était la sortie dudit test Pastebin . Malheureusement, je ne suis pas un gars du matériel et je ne sais pas où aller à partir de maintenant. La sortie des tests suggère-t-elle une panne de lecteur?

Toute aide à ce sujet serait grandement appréciée, car je suis bloqué (essoufflement) sur Windows jusqu'à ce que ce problème soit résolu. Je ne peux plus démarrer sous Ubuntu mais sélectionner Windows dans le menu GRUB fonctionne parfaitement. J'ai pu démarrer en toute sécurité Ubuntu et sauvegarder les petits fichiers dont j'ai besoin. Le formatage est donc une possibilité si cela vous aidera (et ne gâchera pas le gestionnaire de démarrage).

EDIT 1:

J'ai inséré le lecteur d'installation Ubuntu et essayé de démarrer à partir du disque, mais la même chose s'est produite. Je dois avoir manqué le bouton "Appuyez sur n’importe quelle touche", car il faut redémarrer en appuyant sur shift démarré à partir du CD.

La sortie initiale après le redémarrage (sans démarrer à partir du CD) est la suivante:

radeon 000:01;00.0: Invalid ROM contents [ 5.729634] sd 6:0:0:0: [sdd] No Caching mode page found [ 5.729660] sd 6:0:0:0: [sdd] Assuming drive cache: write through [ 185.723262] sd 6:0:0:0: timing out command, waited 180s [ 185.723287] blk_update_request: I/O error, dev sdd, sector 0 [ 185.723300] Buffer I/P error on dev sdd, logical block 0, async page read ...eventually the screen went totally black, fixed by tapping the power button

L'ordre de démarrage du lecteur indiqué est le suivant:

EDIT 4:

Retirer le GPU et démarrer dans le SSD Ubuntu a bien fonctionné. Ce qui est encore plus étrange, c’est que je puisse toujours démarrer Ubuntu, ce qui revient à rajouter le GPU (après avoir nettoyé soigneusement le PC).

Après test et discussion dans un forum de discussion , Ubuntu fonctionne à nouveau sur l'ordinateur.

Le SSD Ubuntu a réussi le test smartmontools
La carte graphique Radeon a été débranchée, nettoyée et rebranchée. Peut-être y avait-il une mauvaise connexion électrique et le fait de débrancher et de rebrancher a corrigé le problème.
