How to recover deleted WD USB hard disk files?

Hello, nearly 10GB of movies, music and documents stored inside my WD USB portable hard drive got deleted last night. Is there any idea to help me rescue them back?
Honestly, this hard drive has not been used over 5 months for some reasons and keeps asking me to format last night. So, I just accidentally clicked the format option and stopped it immediately when I realized it. However, still many important data was lost.

Even though I did have searched and found some free data recovery tools, like free Revuva, 100% freeware iCare Data Recovery Free, TestDisk, Puran File Recovery and more, I still do not know whether they are workable for my case.

Is there anyone that know how to do now? Thanks for any help here.


If the data recovery software dont work then I recommend contacting a data recovery company.
