Mit ddrescue erstelle ich derzeit für jemanden ein Image einer beschädigten NTFS-Partition.
Ausgaben SMART, fdisk, Mountversuch, siehe unten.
Windows lässt sich nicht booten, wenn die Festplatte, auf der die Partition liegt angeschlossen ist,
weil Windows vermutlich versucht die Festplatte zu mounten.
Linux bootet ohne Probleme. Mounten lässt sich die Festplatte unter Linux allerdings nicht.
Das mit ddrescue erstellte Teil-Image lässt sich nicht mounten.
Schätzungweise dürfte sich auch nicht das fertige Image ohne Reparatur einhängen lassen.
Probeweise hatte ich mal ein Teilabbild einer fehlerfreien 2GB NTFS-Partition erstellt;
das ließ sich ohne Probleme einhängen und auslesen.
Von dem Teilimage hatte ich schon mal Daten mit foremost und photorec gezogen.
Der große Nachteil ist allerdings,
dass die wiederhergestellten Dateien ihren ursprünglichen Dateinamen verloren haben.
Sollte sich das fertige Image reparieren lassen, sollten sich die Daten inklusive der eigentlichen Dateinamen auslesen lassen.
Daher meine Frage:
Welche Möglichkeiten gibt es das fertige Image zu reparieren, um es dann mounten zu können?
Vielleicht chkdsk?
Allerdings hatte chkdsk schon erfolglos beim Systemstart versucht (auf dem Computer, auf dem die Festplatte ursprünglich lief) das Dateisystem zu reparieren.
fdisk zur Festplatte.
smartctl gibt besorgniserregendes zu der Festplatte aus.
Der Kurztest musste abgebrochen werden, weil jeweils 10% Rest übrigblieben.

Mount-Versuche unter Linux:
Code:
[root@sysrescue ~]# mount /dev/sdb2 /mnt/sdb2/
The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Falling back to read-only mount because the NTFS partition is in an
unsafe state. Please resume and shutdown Windows fully (no hibernation
or fast restarting.)
ntfs_attr_pread_i: ntfs_pread failed: Input/output error
Failed to calculate free MFT records: Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.
