This question already has an answer here:
I accidentally started a backup from
/dev/sda3 my root partition that is formatted as
ext4 to my backup hard drive
dev/sdb2 which was formatted as
NTFS. I did this using the
dd if=dev/sda3 of=/dev/sdb2
When I recognized the mistake I canceled the command, but now when I run
lsblk -f it lists the backup hard drive as
I am also not unable to mount the disk. I receive this error:
mount: /media/HD: wrong fs type, bad option, bad superblock on /dev/sdb2, missing codepage or helper program, or other error.
Is there anyway to rescue any of the files on the hard drive that may not have been overwritten?
