When the drive is damaged physically. One of the most common reasons for data loss is physical damage. A simple manufacturing defect, or external influences such as shock, dust or power surges may cause internal damage. Anti-static discharge or ESD is also another common cause of failure. Physical damage will inevitably require the help of a data recovery expert. Unless you have a clean room and donor parts, any attempts to recover the data yourself will almost certainly render the data unrecoverable. A data recovery expert will assess the damage to your media before they can determine what parts of it may need to be replaced in order to have the drive working again. Often the expert will use a duplicate hard disk drive of the same make and model to replace damaged parts. Reputable experts will provide a file listing of files and quote for the recovery beforehand.
