My external hard drive brand is iomega with iomega encryption and it was unallocated space.

I accidentally formatted my hard drive and all my files are gone. I used some tool to change the unallocated space to allocated and it was formatted again.

Can i recover my files from my hard drive that I formatted twice?

There are lot of important things inside and I want to recover it. Please help me to save all my files and back to normal.

Give me some precautions to avoid failures and permanent deletion of my files.

Thanks.
