Der Status des Laufwerks selbst, also die SMART-Sachen, wären noch von Interesse.

Beitrag von **smutbert** » 01.10.2016 22:06:31

ich würde aus dem Bauch heraus vorschalgen irgendwo mit

gddrescue ein Image des unverschlüsselte Blockdevices (/dev/mapper/mnt) anzulegen, vor allem damit die vielleicht/vermutlich beschädigte Hardware nicht beim 2. Rettungsversuch komplett versagt.

Dann kannst du ja ausprobieren inwieweit der Dateisystemtreiber mit dem Image (oder besser einer weiteren Kopie des Images) zurechtkommt und schlimmstenfalls auf so etwas wie photorec (aus

testdisk) zurückgreifen, um zu retten, was zu retten ist.

Beim Versuch das Filesystem zu reparieren gab es nur noch rödeln und klackgeräusche. Das wird wohl nichts mehr. Zum Glück habe ich von den wichtigen Sachen ein Backup.
Entschuldigt bitte diesen unnützen Beitrag. Habe aus mangelnder Erfahrung mit Festplattenanalysen gleich einen Beitrag aufgemacht um Hilfe zu erhalten.
Erst dann kamen die Ideen, was gemacht werden muss.
Selbst der Smartselftest hört bei 10% auf. Er geht dann nicht weiter, wenn ich es mit

Code: Alles auswählen

smartctl -l selftest /dev/sda

überprüfen möchte.

Edit:
Hier noch eine letzte Ausgabe:

Code: Alles auswählen

smartctl -l selftest /dev/sda

Platte kaputt.

2TB-Platte besorgen,
Rettungsimage

gddrescue

Code: Alles auswählen

# Erstdurchgang
ddrescue -r0 kaputt image logfile

# dann virtuos kombiniert
ddrescue -r1 [--direct] [--revers] kaputt image logfile

Die Anzahl der Fehlstellen wird dabei zurückgehen,
das heißt jedoch nicht, daß die Daten wirklich ausgelesen werden konnten.
Das Programm ersetzt gegebenenfalls durch NULL.

Sector Sizes: 512 bytes logical, 4096 bytes physical

Dem sollte wohl durch Angabe '--sector-size=' Rechnung getragen werden:

Code: Alles auswählen

# Erstdurchgang
ddrescue -b 4096 -r0 kaputt image logfile

# dann virtuos kombiniert
ddrescue -b 4096 -r1 [--direct] [--revers] kaputt image logfile
