Several days ago, I dropped my USB external hard disk. As a result, I cannot read some of the files. I would like to recover it, and now I am using safecopy. I used the following command,
sudo safecopy /dev/sdb1 data.img --stage1
However, at around 93%, then there is a message something like "cannot read from source". Then I tried to mount this partially recovered image, but failed. What are the things I can do more to recover the data?
I have tried to use
sudo safecopy /dev/sdb data.img --stage1
Now, it is done. Then, I
fdisk -lu data.img
It produces this result,
Disk data.img: 310.8 GB, 310798626816 bytes 255 heads, 63 sectors/track, 37785 cylinders, total 607028568 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: 0xb1bec32c Device Boot Start End Blocks Id System data.img1 63 625137344 312568641 7 HPFS/NTFS/exFAT
Then, I tried to mount with
sudo mount -o loop,offset=32256 -t ntfs data.img /mnt/temp
but failed with this output
Failed to read last sector (625137281): Invalid argument HINTS: Either the volume is a RAID/LDM but it wasn't setup yet, or it was not setup correctly (e.g. by not using mdadm --build ...), or a wrong device is tried to be mounted, or the partition table is corrupt (partition is smaller than NTFS), or the NTFS boot sector is corrupt (NTFS size is not valid). Failed to mount '/dev/loop0': Invalid argument The device '/dev/loop0' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
How should I do to recover the data from here?
