HDD - NTFS partition overwritten - disk seems too small!

#1 Post by Citan » 19 Jan 2014, 00:12

Hi everyone !

As many others, I discovered Testdisk and this forum as a way to resolve a partition problem. While Testdisk gives me a clear light of hope, I'd be grateful for some explanations and advices on the steps to follow.

FACTS
I own an external, 2,5 inches 2TB hdd (1,8 Tio). I had it formatted as a unique NTFS partition covering nearly all space (except for a few Gio that I kept at end of disk, in case I wanted someday to install a live system).

Last week, I wanted to install the latest Ubuntu on my computer, by first putting it on a small external drive (a key of 1,8 Gio). You'll guess what happened... I chose the wrong device in the live-system creation tool and erased my 2TB.

Hopefully Testdisk is here. Following the recommandations (unmounted disk and such), I runned it. It first see the new FAT32 partition, only with Deeper Search does it see other partition. Finally, testdisk lists...
- the all new FAT32 partition;
- a HFS - NTFS partition which I suppose is my "good" partition;
- a FAT16 partition, coming from whoknowhere;
- a FAT12 partition, idem...

So news seems good, he sees a NTFS partition. Still, 2 problems.
- Testdisk displays "The Harddisk (2000 GB / 1863 GiB) seems too small! (<2422 GB / 2256 GiB)." Not sure what it means but doesn't seem very good.
- It says "NTFS found using backup sector, blocksize=4096, 1979 GB / 1843. But when I "enter it" with P to list files, its says "Can't open filesystem. Filesystem seems damaged".

So, with this, I'm not sure what is the right next step. If any can help troubleshoot this it will be much appreciated.
The full testdisk log (2 scans with different options) and some screenshot are accessible through this link (I can attach them directly if preffered).

Thanks in advance (French version below in case of)!

Bonjour à tous !!

Comme beaucoup d'autres, j'ai découvert Testdisk et ce forum à l'occasion d'un souci (bon, ici grosse boulette de ma pomme). L'occasion faisant le larron, je viens demander quelques éclaircissements sur les indications de testdisk et la marche à suivre.

Les faits
Je possède un disque externe 2,5 pouces de 2 To (1,8 Tio). Il disposait d'une unique partition NTFS qui couvrait quasiment l'intégralité du disque (j'avais dû laisser quelques Go de secours "au cas où" pour installer un système live).

La semaine dernière, je voulais réinstaller un système Ubuntu live sur une clé externe d'1,8 Gio pour ensuite réinstaller mon système principal. J'avais donc branché mon disque externe pour sauvegarder toutes les données.

J'ai ensuite lancé l'utilitaire de création Ubuntu, et là, par manque d'attention car habituellement je débranche tout disque externe avant manip externe, j'ai sélectionné le disque de 1,8 Tio au lieu du disque 1,8 Gio.
Anéfé c'est très con. ^^^^

Je n'ai rien d'extrêmement précieux sur ce disque, mais j'aimerais tout de même le récupérer.
Testdisk ne voit que la nouvelle partition FAT32 par défaut. Après Deepsearch, il me trouve plusieurs partitions :
- la FAT32 créée par l'outil d'Ubuntu ;
- une HPFS - NTFS qui semble être la bonne ;
- une partition FAT12 (????) ;
- une partition FAT16 (?????).

Deux soucis :
- Il m'indique The Harddisk (2000 GB / 1863 GiB) seems too small! (<2422 GB / 2256 GiB).
- Il m'indique avoir trouvé la partition NTFS grâce au secteur de backup. En revanche lorsque je rentre avec 'P' pour lister les données, il me dit que le système de fichiers est endommagé.

Que faire ? Merci d'avance pour vos conseils.

Re: HDD - NTFS partition overwritten - disk seems too small!

Hi again, thanks for accepting the thread.

I saw in other threads that in fact you always insert logs and screenshots since easier (in spite of added thread length). So I updated the opening post. Thanks in advance for your help!

------------------
Rebonjour à tous. Merci à l'équipe d'avoir validé le sujet. J'ai constaté dans les autres fils que la meilleure pratique reste d'inclure les logs et captures au sein du post initial, même si cela les rallonge significativement. J'ai donc mis à jour en conséquence.
Merci d'avance à tous pour votre aide !
