disque de 1 TO dont le contenu est inconnu à 98.8% !!!!

Bonjour,
dans un autre post, on a pu voir que j'avais 2 disques : 1 disque pour Windows 10, Ubuntu 18.04, etc... et un disque dur de 1TO dont le contenu est inconnu à 98,8% et ce qui reste était semble-t-il une partition recovery, que dois-je en penser selon vous ?

Voici un boot-info (parce que décrire une application graphique, ça rend pas les choses pas claires) :

Boot Info Script 8f991e4 + Boot-Repair extra info      [Boot-Info 25oct2017]

=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda1/efi/.../grub*.efi !

Si votre ordinateur redémarre directement sur Windows, essayez de changer l'ordre de démarrage dans votre BIOS.
Si votre BIOS ne permet pas de changer l'ordre de démarrage, changez l'entrée de démarrage par défaut de l'amorceur Windows.
Par exemple, vous pouvez démarrer Windows, puis saisir la commande suivante dans une invite de commande en mode administrateur :
bcdedit /set {bootmgr} path \EFI\...\grub*.efi


=================== User settings
The settings chosen by the user will not act on the boot.

Re : disque de 1 TO dont le contenu est inconnu à 98.8% !!!!

Bonjour
L'autre post que tu aurais pu citer est là

Dans le boot-info, on voit que le premier disque est un SSD

lrwxrwxrwx 1 root root  9 Oct 25 11:29 ata-SanDisk_SD8SNAT-128G-1006_162924422246 -> ../../sda

Il est donc normal d'installer le logiciel dedans. (windows y est )

sda3: __________________________________________________________________________
    File system:       ntfs
    Boot sector type:  Windows 8/2012: NTFS
    Boot sector info:  No errors found in the Boot Parameter Block.
    Operating System:  
    Boot files:        /Windows/System32/winload.exe

et tu as installé ubuntu 18.04 dedans

sda5: __________________________________________________________________________
    File system:       ext4
    Boot sector type:  -
    Boot sector info: 
    Operating System:  Ubuntu 18.04.3 LTS
    Boot files:        /boot/grub/grub.cfg /etc/fstab

Cependant tu as un gros disque dur composé de deux partitions en NTFS

Partition  Attrs   Start Sector    End Sector  # of Sectors System
/dev/sdb1                 2,048 1,928,865,791 1,928,863,744 Data partition (Windows/Linux)
/dev/sdb2      R  1,928,865,792 1,953,523,711    24,657,920 Data partition (Windows/Linux)

Mais la  premiere n'est pas montable et la seconde a un label recovery

/dev/sdb1                                                          
/dev/sdb2        B41603EE1603B102                       ntfs       RECOVERY

La cause du non montage est assez obscure

NTFS signature is missing.
Failed to mount '/dev/sdb1': Argument invalide
The device '/dev/sdb1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
mount /dev/sdb1 : Error code 12
mount -r /dev/sdb1 /mnt/boot-sav/sdb1
NTFS signature is missing.
Failed to mount '/dev/sdb1': Argument invalide
The device '/dev/sdb1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a

A mon avis, ce disque contient une version de windows qui a eu un gros problème  ==> Windows chiffré par bitlocker?
- Si tu penses que tu n'as aucun fichier à toi dans cette partition, le plus simple est de la supprimer ainsi que SDB2 et refabriquer une nouvelle partition NTFS destinée à recevoir tes données personnelles (Voir méthode de bluc  )
- Si tu penses que tu as des fichiers dedans, il faudrait installer testdisk pour explorer la partition.

Re : disque de 1 TO dont le contenu est inconnu à 98.8% !!!!

sdb2 semble bien être une partition recovery (elle doit faire une taille de 12 Gio), par contre sdb1 n'a pas la signature NTFS (il me semble qu'elle se trouve au 4ème octet du début de la partition). On devrait aussi y trouver des messages d'erreurs potentielles.
sdb1 est peut être une partition chiffrée

Re : disque de 1 TO dont le contenu est inconnu à 98.8% !!!!

A mon avis, ce disque contient une version de windows qui a eu un gros problème

ou encore

sdb1 est peut être une partition chiffrée

J'assure que je ne me suis encore jamais intéressé à ce grand domaine qu'est la cryptographie. Et puis, mon pc est un pc "gaming" Je me dis que je devrais peut-être les contacter pour savoir ce qu'ils mettent dans leurs produits...   

Si tu penses que tu n'as aucun fichier à toi dans cette partition, le plus simple est de la supprimer ainsi que SDB2 et refabriquer une nouvelle partition NTFS destinée à recevoir tes données personnelles

Pour moi, je considérais que Windows écrivait des patchs ou des recovery quelque part dans ce 2ème disque (à savoir sdb1 ou sdb2 en particulier ; j'en sais rien ou je ne sais plus...).
Après, concernant particulièrement sdb1, c'est vraiment un mystère...

J'installe et j'utilise le paquet.
Je choisis un type de partition.

Disk /dev/sdb - 1000 GB / 931 GiB - HGST HTS721010A9E630

Please select the partition table type, press Enter when done.
[Intel  ] Intel/PC partition
[EFI GPT] EFI GPT partition map (Mac i386, some x86_64...)
[Humax  ] Humax partition table
[Mac    ] Apple partition map
[None   ] Non partitioned media
[Sun    ] Sun Solaris partition
[XBox   ] XBox partition
[Return ] Return to disk selection

Je fais une analyse du disque comme si celui-ci était bootable (j'ai sélectionné l'option "intel") : 

TestDisk 7.0, Data Recovery Utility, April 2015
Christophe GRENIER <grenier@cgsecurity.org>
http://www.cgsecurity.org
Disk /dev/sdb - 1000 GB / 931 GiB - CHS 121601 255 63
Current partition structure:
     Partition                  Start        End    Size in sectors
 1 P EFI GPT                  0   0  2 267349  89  4 4294967295
Bad sector count.
No partition is bootable

Mis à part "Analyse" que je viens de faire, que pensez-vous de ces autres options ?

[ Analyse  ] Analyse current partition structure and search for lost partitions
[ Advanced ] Filesystem Utils
[ Geometry ] Change disk geometry
[ Options  ] Modify options
[ MBR Code ] Write TestDisk MBR code to first sector
[ Delete   ] Delete all data in the partition table
[ Quit     ] Return to disk selection

Mais comme j'avais pas trop compris ce que c'était ce disque (étant débutant), je prends la voie de l'option "EFI GPT" et avant analyse, la ligne de commande me donne ça :

Disk /dev/sdb - 1000 GB / 931 GiB - CHS 121601 255 63
Current partition structure:
     Partition                  Start        End    Size in sectors

No FAT, NTFS, ext2, JFS, Reiser, cramfs or XFS marker
 1 P MS Data                     2048 1928865791 1928863744 [Basic data partition]
 1 P MS Data                     2048 1928865791 1928863744 [Basic data partition]
 2 P MS Data               1928865792 1953523711   24657920 [Basic data partition]

Après analyse, ça me donne ça :
[L'ANALYSE EST TRES TRES TRES LONGUE, JE FERAIS DONC UNE MODIFICATION PLUS TARD...).

Re : disque de 1 TO dont le contenu est inconnu à 98.8% !!!!

En fait, Il faudrait que tu lances windows   et qu'avec son  gestionnaire d'espace disque virtuel, tu regardes ce  qui se présente.
Je sens l'arrivée de partitions logiques.

Tu pourras faire une capture d'écran et la poster sur un site de partage https://doc.ubuntu-fr.org/capture_d_ecr … re_d_ecran

Re : disque de 1 TO dont le contenu est inconnu à 98.8% !!!!

Ce que tu appelles "gestionnaire d'espace disque virtuel" ressemble à l'application windows qui gère les partitions par défaut. Je peux aller voir, mais franchement, je n'attends rien de particulièrement prometteur avec cet outil, quoique ça soit le seul OS qui ait pu mettre quelque chose sur ce disque jusqu'à présent.
Voici un screen :

Quant à l'outil en ligne de commande, il me semble un peu trop muet...

DISKPART> sel disk 1
Le disque 1 est maintenant le disque sélectionné.
DISKPART> sel partition 1
La partition 1 est maintenant la partition sélectionnée.
DISKPART> rescan
Veuillez patienter pendant que DiskPart analyse votre configuration...
DiskPart a fini d’analyser votre configuration.

Et puis, ce genre de tutos ne sert à rien : https://docs.microsoft.com/fr-fr/window … management

Bref, demain, j'appelle mon service après-vente de mon constructeur.

Bonsoir.
Il est fort probable que ton  fabriquant ait oublié de l'initialiser.
Peut-être que c'est un disque d'ocasion.
Tu devrais installer https://doc.ubuntu-fr.org/smartmontools
et donner le retour de la commande du paragraphe 3.1  si tu installes  sous ubuntu.
Cependant, tu peux aussi installer smartctl dans windows. https://www.smartmontools.org/wiki/Down … owspackage

Mais est-ce vraiment utile puisque j'ai formaté la partition avant la commande ?

Re : disque de 1 TO dont le contenu est inconnu à 98.8% !!!!

Bonjour
C'est quand même bon de savoir que ton disque fonctionne bien malgré son àge

  9 Power_On_Hours       ====>     9436

Statistiquement parlant, il est usé à 21%  (100-79)

Les données SMART concernent l'état du disque. Elles ne portent pas sur les partitions.
(Tu peux supprimer toutes les partitions, les données SMART seront inchangées.)
La commande sudo smartctl doit porter sur /dev/sd<lettre> et pas sur /dev/sd<lettre><nombre> (c'est expliqué dans la Doc smartmontools).

Je ne comprends pas

192 Power-Off_Retract_Count        983055

en 9.436 heures. (vs 48.516 Load_Cycle_Count)

À titre de comparaison, un de mes propres Hitachi - dont l'aptitude au parcage n'est malheureusement pas réglable - présente ceci :

  9 Power_On_Hours          0x0012   099   099   000    -       12270
 12 Power_Cycle_Count       0x0032   100   100   000    -       1116
192 Power-Off_Retract_Count 0x0032   099   099   000    -       1609
193 Load_Cycle_Count        0x0012   099   099   000    -       1609 

Pour en revenir à ton Hitachi, ceci

184 End-to-End_Error        0x0033   100   100   097    Pre-fail  Always       -       0

est bizarre aussi.
  J'avais déjà l'impression qu'Hitachi, à l'époque où il fabriquait des HDD, traitait les données SMART par-dessous la jambe. Ce cas renforcerait plutôt mon impression.

J'ai lu la documentation, mais sur Windows, les partitions marchent seulement comme je vous ai montré sinon, ça n'affiche rien !
Mais peut-être qu'il y a quiproquo (je n'ai pas de formation en informatique...). C'est pourquoi, je ne sais quoi vous répondre sur les prétendues erreurs qu'on me soumet.
En tout cas, je fais la même commande avec le disque C: et ça semble m'afficher la bonne partition sur le bon disque.
