External hard drive corrupted after power failure

"An error occurred while accessing 'Seagate Backup Plus Drive', the system responded: The requested operation has failed.: Error mounting: mount exited with exit code 1: helper failed with: $MFTMirr does not match $MFT (record 0). Failed to mount '/dev/sdb1': 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"

That had my final research on it to start my business, I was hours away from finally starting up a business project, that was days of work and all kinds of one of a kind personal data on it I can't reproduce.

I'm using a live CD, version 2 something, and have no internal hard drive. What do I do?

since it is NTFS, you may have the greatest luck using CHKDSK from a Windows installation.

if your data are really important then please do a backup of entire drive before you do anything with it. please connect second external drive and run:

Code: Select all

dd if=/dev/sdX of=/mnt/sdY/backup.img
where sdX is the faulty drive and sdY is the one used for a backup.

if dd interrupts while reading then you'll have to use ddrescue instead:

once you have a backup done then please disconnect the faulty drive immediately and start performing recovery tasks on the backup image (do a copy of it first) and not the drive.
