Hello,
a coworker asked me to try to recover data from his old WD My Book World Edition 1.5TB. The device itself is dead, power supply has failed and so did the motherboard. And one of the two disks stopped working too, but the other one, 750GB WD7500AAKS seems to be working fine and I can see partitions on the drive.
These are the partitions:
Disk /dev/sdc: 750.2 GB, 750156374016 bytes
255 heads, 63 sectors/track, 91201 cylinders, total 1465149168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00010907
Device Boot Start End Blocks Id System
/dev/sdc1 48195 5927984 2939895 fd Linux raid autodetect
/dev/sdc2 5927985 6136829 104422+ fd Linux raid autodetect
/dev/sdc3 6136830 8112824 987997+ fd Linux raid autodetect
/dev/sdc4 8112825 1465144064 728515620 fd Linux raid autodetect
If I run gparted, I see that first and third partitions are ext3, the second one is swap, but the interesting one, the fourth partition … has an unknown file system. I googled … a lot, found out that sometimes these partitions are in XFS file system. This one doesn’t seem to be:
xfs_check: /dev/sdc4 is not a valid XFS filesystem (unexpected SB magic number 0x00000000)
xfs_check: WARNING - filesystem uses v1 dirs,limited functionality provided.
xfs_check: read failed: Invalid argument
cache_node_purge: refcount was 1, not zero (node=0x1c6fed0)
xfs_check: cannot read root inode (22)
bad superblock magic number 0, giving up
I even tried R-Studio and there also was the file system on the fourth partition “unknown”. UFS Explorer and NAS Data Recovery didn’t help either. :-/
Any suggestions what to do? Considering the hard disk seems to function properly it shouldn’t be hard to copy data from that partition, but how [deleted] do I mount that?
