partition raw sur disque de 4To

#1 Post by egirard1 »

bonjour à tous,

mon disque de sauvegarde de 4to est passé en raw recemment sans que je ne voie le truc arriver.

j'essaye de recuperer avec testdisk mais j'ai quelques questions:

1 - lorsque je lance testdisk, il voir la partition de 4To. je la choisis et lance le scan.voici le contenu du log.

Disk \\.\PhysicalDrive2 - 4000 GB / 3726 GiB - CHS 486401 255 63, sector size=512 - SABRENT, S/N:22222222222222220072, FW:0056

Partition table type defaults to EFI GPT
Disk \\.\PhysicalDrive2 - 4000 GB / 3726 GiB - SABRENT
Partition table type: EFI GPT

Analyse Disk \\.\PhysicalDrive2 - 4000 GB / 3726 GiB - CHS 486401 255 63
Trying alternate GPT
Current partition structure:
Trying alternate GPT

search_part()
Disk \\.\PhysicalDrive2 - 4000 GB / 3726 GiB - CHS 486401 255 63
file_win32_pread(628,1,buffer,34(0/0/35)) read err: read after end of file
file_win32_pread(628,1,buffer,35(0/0/36)) read err: read after end of file
file_win32_pread(628,14,buffer,36(0/0/37)) read err: read after end of file

2 - mon pc a rebooté de force à cause d'une mise à jour au bout de 2 jours - merci Crosoft.

3 - je voudrais bien relancer le test mais je n'ai aucune idée du temps que ca peut prendre pour 4To. si quelqu'un peut m'éclairer ...

4 - il y a de nombreux read err ... j'imagine que c'est normal. Est-ce que il va trouver quelque chose quand même sachat que mon disque était à moitié plein.

Merci pour vos réponses.

Have you tried the -d parameter?
No SMART support is unusual.
How old is this drive?

ok some more informations on my disk.

this is a ST4000LM024 - i bought it in 2017.

it was initialy an external disk. so to test the disk i opened the box ( Maxtor M3) and bought a SABRENT sata to USB converter.

so when i run smartctl command it returns:

when i run test disk. the disk is detected and size is quite ok 4000GB and 3726 GiB
and seen as 3726 Go RAW.

BUT

when i connect directly the drive in my laptop via a SATA extend cable ( its just a cable for connecting the drive which is a bit fat to be housed in my laptop),

i finds the drive but no size info - and whatever smartctl command returns an error.

thank you for helping.


start of edition :

i've reconnected the drive into the box and it sees size of 140GB :) sector size = 32k

and


C:\Program Files\smartmontools\bin>smartctl -a -d ata /dev/sda

Pardon, je me suis trompé de language, ici on parle français!

Je ne sais pas si votre "SATA extend cable" passe aussi le courant nécessaire. Le mieux c'est de brancher votre disque dur en taille de 2,5'' en direct avec un ordinateur regulier pour pouvoir voir ce que SMART donne. Recupérer les données SMART peux aussi fonctionner avec des boites extérieurs ou des "docking stations".
Pour étre sûr qu'il n'y pas un problème avec smartmontools vous pouvez utiliser aussi "Crystal Disk Info".

Pour la récuperation des données c'est mieux de remettre le disque dur dans sa boite parce qu'elle contient souvent d'électronique qui fait apparaitre des secteurs des 512 octets come des secteurs de 4096 octets.
Cette émulation permet d'utilisier une ancienne table de partitions nommée "MBR".

bonsoir, pas de pb pour la langue.

je câble utilisé était une extension complète du conecteur SATA + Alim donc tout passait directement du PC au disque.

je vais essayer avec le soft dont vous me parlez. Par contre j'ai essayé de le remettre dans sa boite. ca donne les dernières infos délirantes sur le disque qui ferait 140 To !!

je vous fais ca demain matin.

bien cordialement.

j'ai repris les manips ce soir.

sans résultat. le logiciel Crystaldiskinfo ne voit pas le disque.

testdisk le voit bien et windows aussi en mode raw de 4To en direct sur le pc ou 140To dans sa boite.

cordialement.

Dans ce cas malheureusement, il ne vous reste que de consulter un service professional.
