Opening up sensitive hard discs can run the risk of creating further damage to these items, while the fact they are manufactured in sterile, dust-free conditions means individuals also risk exposing airborne particulates into the device’s inner working.

As a result, if the system is subsequently powered back up after being opened in a non-clean environment, it will likely cause the heads to crash and the whole data set contained on the drive could be lost.

Furthermore, damage caused to the surface of the drive or the head stack assembly could also render further recovery efforts fruitless.

It is therefore important that in times of emergency, companies turn to professional data recovery experts, who will have all the necessary equipment and skills to complete the recovery process without the risk of further data loss.

While a full recovery of data sets can never be completely guaranteed, – as this process will often depend upon the type of incident that has occurred – businesses would be foolish to run the risk of further losses by taking a DIY approach.

It is wise to choose a data recovery company who has a track record in recovering from the type of data loss you have experienced.
