Today however, it is possible to recover data from a damaged hard disk even though it is extremely difficult and time consuming. In addition to tampering or a virus, sometimes hard drives jut stop functioning and this can be a huge cause of stress and worry. Listed below are a few reasons for the malfunctioning or failure of hard drives.

First, your hard drive is handed over to a professional technician who is experienced and knowledgeable. There are different levels of priority for different kinds of damages. For example, if data is lost because of a virus in the system or because the hard disk is physically damaged severely, technicians will consider it a high priority situation. In these cases, the main disk will first be accessed to see if the data can be viewed and retrieved. If this is possible, all the data will simply be copied on to a new storage device.

If the device is too damaged, then a survey is done to see what components can be replaced. Once these components are replaced, the data is then retrieved and copied on to a new disk. But to do the retrieval, technicians first carry out a process known as analysing low level data sectors. Following this, all of the data on the damages device is removed by ‘de-stripping the servers’ on which it is contained.
