Many data recovery companies will often ask you for your disk drive that you want data to be recovered from so that they can asses the problem and tell you how much it will cost. This leaves you very open to exploitation from these mac file recovery companies because once they have the hard drive in their possession, they can decide to quote a very big amount of money that is way more than the actual value of the recovery service. Due to the fact that they have the hard drive, you will be held at ransom and you might be forced to pay the amount that they are asking for in order to recover your lost data or information.
You should always demand for a standard rate that they normally charge for file recovery. This will ensure that you are not held at ransom and they do not overcharge you. If the quote is too high for you, you can always seek the services of another recovery company because they are quite a number.
