WD External Hard Drive Recovery on macOS Sierra 10.12

Hello Everyone,

Everything was fine after I upgraded to macOS Sierra but accidentally formatted my backup 2 TB WD External hard disk resulting in loss of an important video files. Could someone here suggest me a free tool to recover back my video?

macOS Sierra 10.12
1 TB (Internal), 2 TB (External)
4 GB RAM

No data recovery software are free. I recommend you try Stellar Phoenix Mac Data Recovery (macOS Sierra 10.12) compatible to recover erased videos from WD external hard drive. Source - http://www.stellarinfo.com/data-recovery-mac.php
