Mistakenly overwrite external HDD with iso using dd

Did a

Code: Select all

sudo dd if=/path/to/iso of=/dev/sdX bs=4M;sync
on the wrong mounted drive and overwrote my Western Digital NTFS usb 3.0 1TB external drive. It had ~500GB of files on it and the iso that I overwrote it with is less than 500MB. I have used TeskDisk to complete a quick search which reported 'Structure: Ok'. I'm assuming it's just looking at the image and doesn't know about the deleted files.

I have heard NTFS keeps a backup of it's MBR somewhere near the end of the volume. Anyway I can get TestDisk to search for the deleted MBR and attempt a restore before I try individual file recovery with PhotoRec?
