With the growing need for more and more storage, you may have multiple external hard disks at your disposal. At this point in time, external hard drives are also the most common to fail. This is due to the fact that while internal hard disks are safely inside your computer, external hard disks are generally within arm’s reach on your desk. Consequently, the most common failure type for these drives is failed heads which is caused from being dropped or knocked over onto a hard surface. If your device has been dropped your external hard drive is most likely clicking, grinding, beeping or failing to initialize. This is due to the fact that when you drop your external the heads are damaged in the process (more on this later). Generally drives in this predicament need parts replaced which entails a rebuild of your external device. These types of failures fall under a Level 2 or a Level 3 Recovery as the drive normally has to be rebuilt.
Failed Hard Drive Heads
When the drive is knocked over while running, the heads often make contact with the surface of the platters which generally causes permanent data loss at least to some extent. The heads (as shown in the first picture) are very small and extremely delicate. When the heads come in contact with the platter you will often see bent or broken components which will inhibit your drive from reading or writing data. Even if your heads look undamaged when we open your drive in the lab, it is still possible failed heads are the culprit. This is due to the sensitivity of the magnetic heads. Minor contact with the platters will cause micro scratches in the head surface which will quickly degrade the head stack until the point that you can no longer read or write data. If you have dropped an external hard drive and fear that you may have caused damage, we recommend shutting down your device immediately. We more than likely will still be able to recover your data, so it is strongly recommended to stop the running drive immediately and do not attempt Do It Yourself Techniques. The reason for this is the more the heads make contact with the platters, the more data you lose and the smaller your chance of recovery becomes. If you did not drop your drive and your drive is not clicking or beeping, or failing to initialize, your drive may be recovered under a Level 1 Recovery, and your data may possibly be recovered using the proper DIY Techniques. Before attempting any DIY Techniques, it is strongly recommended to contact a professional for a free recommendation. Remember, if your data is valuable, DIY Techniques are never recommended and you should Contact us, or Request a Quote immediately.
