Data recovery service tecommendation

My Passport 4TB has failed. I’m pretty sure it is a control board failure. I have researched reviews on the services that WD has listed and have narrowed it down to and OnTrack. Does anyone have any personal experiences or other feedback?

Both of these services are good, but you will find some errors while restoring the data. You see, many times the data gets corrupt and unusable after recovery. You can check these suggestions from Techradar and check the comparisons before making a purchase.
