I would like to share my personal experiences wit you here.
A few days ago, I was stuck under similar problems. At that time, I had lost all of my important business files by mistakenly formatting the external hard drive without any backup. So, I started to searched “data recovery tool” over the internet and finally found an external hard drive recovery freeware that recovered all my files back. So, it is really worth a shot.
I hope you guys could learn a lesson to back up your crucial data all the time from my experiences.
I hope this freeware could help much more people.
