Sometimes a mechanical problem can make a HDD produce some strange sounds
. A person who does not know much cannot exactly trace the root of such noises. Again, if this occurs today, disconnect that drive and pay for servicing. This is much easier and safe than trying to correct an error one knows nothing about. Allow those who know all about it to help. They might advice a customer to replace some drive parts or get a new drive all together. If any computer user is looking to use this service, it is good to know that prices are quite high. Since harddrive data recovery is intricate, simply pay and solve the problem finally.
