6 Reasons Why Hard Drives Fail
Just like any other gadgets, hard drives may fail one time or another and when this happens, you might get worried about your data since this can halt all the operations of your business. Luckily, there are data recovery companies available and you might call them for your rescue. There are two major causes of hard disk failures namely: logical and physical. Sometimes, they can be both and when this happens it can be tricky trying to recover your data. A data recovery company will help you in extracting data from a faulty drive and place it onto a mechanically stable hard drive. Below are the most common failures that are associated with hard drives:
Electrical failure
The PCB board is charged with the task of communicating, controlling and coordinating the task of reading and writing data between a computer and the hard drive. If the PCB on the board of your hard drive gets damaged, you lose access to the vital data. The damage is caused by power spikes or surges and this may affect the read-write head circuitry.
Mechanical failure
This comes as a result of some impact or just wear and tear. There will be no prior warning that the read-write head, motors or other internal components are going to be faulty. As such, head crash is the most dreaded thing when it comes to mechanical failure of a hard drive. Most data recovery companies have the necessary expertise to recover any data lost but this will entirely depend on the extent of the damage.
Logical failure
This is caused by any other type that is not physical in nature. Usually, it can be the easiest or sometimes the most difficult to handle when it comes to data recovery. However, the task will depend on the circumstances that lead to the failure and or the extent of the damage. Since some of these failures are inevitable, you might want to work closely with a reputable data recovery company and more so, one from your region. Logical failure can include but not limited to: accidental format, accidental deletion, software bugs, file corruption and viruses.
Bad platter area
Sometimes, there are sectors of the hard drives that become inaccessible. The platter surface wears out with time, and this can cause bad sectors in your drive. Other causes include manufacturing defects, head crash and tracking errors. Different techniques are used by the service providers to maximize the yield of recovery.
Complex failure model
Hard drives may take years and years before they get faulty. As such, they may not fail just at once. It is a combination of some of the failure modes that slowly leads to their damage. One failure mode may trigger the occurrence of another, and as time goes by, the drive may become inaccessible.
Firmware failure
Firmware is the software that enables the drive to perform its tasks and it is only accessed by the hard drive manufacturers. There would be no communication between your computer and the drive if this software lacked. You can seek after the services of a qualified and licensed data recovery company to recover all the data lost due to hard drive failures. You can run a simple online search and you will be good to go.
