Essential Data Recovery gave me a fixed price in advance for recovering data I lost when an external backup drive had failed. They offered a free analysis up front together with a very reasonable fixed price up front which covered all costs unless they needed to buy parts or provide a disk on which to put the data. The recovery was very effective. I would highly recommend their service and avoid organisations out there that offer a free analysis then come back with an extortionate quote for delivering the accessible data afterwards. Much better to know what you are going to pay in advance. Furthermore, communication was excellent and there was no pressure applied at any point in the decision-making process. They made a very worrying situation much easier to handle. Thank you!!
