Seagate-HD File System nicht erkannt

#1 Post by pinotto » 20 Sep 2014, 21:34

Hallo,

ich habe eine 2TB-Festplatte Marke Seagate, Mod. Barracuda Green, die ich für Backups benutzt habe und daher meistens an e-SATA- seltner an USB-Anschluss ans Linux-System (OpenSuse) eingebunden habe.
Sie hatte nur eine einzige (nicht boot-fähige) ext4-Partition.

Plötzlich kann OpenSuse die Festplatte nicht mehr mounten. Das Partition-Tool von OpenSuse erkennt jetzt noch die Partition und deren Typ ("Linux native") kann aber das File-System nicht mehr feststellen.

TestDisk erkennt die Festplatte und die Partition richtig und kann auf (schätzungsweise alle) Dateien die, dort gespeichert wurden. Leider habe ich aber nicht geschafft, weder die Partitionstabelle noch die MBR erfolgreich neu zu schreiben.
Dann habe ich gedacht, ich konnte mittels "fsck" Partitionstabelle und Filesystem wieder erstellen lassen. Aber fsck.ext4 meldet für alle von TextDisk gefundene Superblocks, dass diese unlesbar. Ist es nicht komisch?

Was kann ich noch tun, Partition und File-System zu retten?

Vielen Dank im voraus für jegliche Hilfe.

Bräuchte log file von TestDisk um es zu beurteilen.
Hattest du wenn TestDisk deine Daten diese bereits kopiert?

Fiona,
vielen Dank für dein Einsatz.
Du hast geschrieben:

Ja, ich habe eigentlich einge screen shots und 4 log files, da mehrere Versuche unternommen.

Hier die wichtigsten 2.
Erster Log-Datei : allgemeine Analyse und u.a. Versuch, die Partitionstabelle zu "schreiben".
Ich habe aus praktischen Gründen die Liste der gefundenen Dateien gelöscht und durch 2 kommentierte Zeilen ersetzt.

Re: Seagate-HD File System nicht erkannt

Deine Partition ist bereits in der Partitionstabelle.
Hattest du testdisk mit su oder sudo als superuser ausgeführt?
Hattest du mit fsck diese Vorgehensweise getestet?
http://www.cgsecurity.org/wiki/Sicherun ... cks_finden
Trifft auch für ext4 zu.
Wenn TestDisk deine Daten anzeigt, kopiere sie bitte zuerst.
Unten am Screen findest du alle Befehle zum kopieren.
Warum in TestDisk gegenwärtig alle Superblöcke als nicht lesbar angezeigt werden, kann ich noch nicht zuordnen.

Hallo Fiona,

Hattest du testdisk mit su oder sudo als superuser ausgeführt?
Testdisk habe ich mit "su" ausgeführt, es ist mir bequemer als vor jedem Befehl "sudo" einzutippen.
Hattest du mit fsck diese Vorgehensweise getestet?
http://www.cgsecurity.org/wiki/Sicherun ... cks_finden
Ja, das habe ich mit allen von Testdisk ermittelten Superblocks und jedes mal erkennt fsck den Superblock nicht,
Beispiel:

Code: Select all

# /sbin/fsck.ext4 -b 4096000 -B 4096 /dev/sdd
e2fsck 1.42.8 (20-Jun-2013)
/sbin/fsck.ext4: Ungültige magische Zahl im Superblock beim Versuch, /dev/sdd zu öffnen

Der SuperBlock ist unlesbar bzw. beschreibt kein gültiges ext2
Dateisystem. Wenn Gerät gültig ist und ein ext2
Dateisystem (kein swap oder ufs usw.) enthält, dann ist der SuperBlock
beschädigt, und sie könnten e2fsck mit einem anderen SuperBlock:
    e2fsck -b 8193 <Gerät>
Die Dateien habe ich fast komplett kopiert.
Danach möchte ich nochmals fsck von einem Linux-Live-Version versuchen.

Vielen Dank nochmals für Deinen Einsatz.
