They claimed £120 fixed fee and they can recover my data. They got the Hard drive and then said it needed to be opened in a clean room and the cost would be around £500. I told them to leave it and they returned my hard drive. I then took the hard drive to Cheadle Data recovery in Stockport who had a look at the hard drive. They told me what I had been told by Essential data recovery was a pack of lies. Cheadle Data recovery was able to recover the data without using a clean room at half the price quoted by Essential Data.
