misuse command dd, how to recover

[cheng chen]

Hi all,

I just input a wrong output device file of the dd command

it should be "dd if=xxx.iso of=/dev/sdc"

but I input "dd if=xxx.iso of=/dev/sdb",

so my hard disk partition is ruined. The xxx.iso is just 3GB, but I have
400GB data in the disk which means other data are still there.
Is there anything I can do to get the files back to me. It's partition type
is NTFS.

Thank
