Ich bin Neuling hier ... Bitte seid lieb zu mir. 😛
1. Problem
Ich möchte ein Dateisystem/ eine Partitionstabelle/ meine Daten von einer Festplatte wiederherstellen und brauche dringend Hilfe. Die Daten sind sehr wichtig und es wäre super, wenn ich sie mit eurer Hilfe wiederherstellen kann!
2. Hintergrund
Ich hatte versucht meine externe 8TB Festplatte mit Bitlocker auf Windows 10 (ich weiß: ziemlich doof!) zu verschlüsseln. Aus unerklärlichen Gründen ist dieser Vorgang gescheitert. Am Anfang konnte ich noch auf die Daten zugreifen. Nachdem ich aber die Festplatte das nächste mal angeschlossen hatte, wird die Festplatte nur als 1404 GB groß angezeigt und es sind keine Daten sichtbar.
3. Infos zur Festplatte
Der Befehl (smartmontools):
1 | smartctl -a /dev/sdb |
zeigt mir korrekte Details zur Festplatte (8 TB Seagate) an:

Mit
1 | parted /dev/sdb print |
aber auch im System oder bei testdisk wird die Festplatte komischerweise nur mit einer Größe von 1404 GB angezeigt:
1 2 3 4 5 6 7 8 | Model: ST8000AS 0002-1NA17Z (scsi) Disk /dev/sdb: 1404GB Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 1049kB 1404GB 1404GB primary ntfs |
Wie kann ich die Festplatte/ das Dateisystem/ die Partitionstabelle wiederherstellen, um die Daten zu retten?
4. testdisk
Mit testdisk konnte ich die Partitionstabelle bzw. das Dateisystem nicht wieder reparieren.
Ganz lieben Dank schon mal für eure Hilfe.
