The firmware is a computer program that ensures the proper operation of the hard drive. It coordinates the action of the platters, the electronic board (PCB) and the read heads. The origin of a firmware failure can therefore stem from a software or hardware cause. It results in a malfunction of the hard drive, which may no longer be recognised by the computer and prevent you from accessing the data stored on it. Although leading to the same consequences, firmware failures are distinct from logical failures, which result from human error.
How can you identify firmware failures?
Here are the various symptoms that should alert you.
- The hard drive does not start up or does not mount.
- The hard drive runs slowly. A “not responding” alert appears regularly due to a malfunction of the firmware or an electronic component.
- Repeated clicking noises can be heard. This may indicate a fault in the mechanical components, with the read heads scraping the platter during operation.
- A “not initialised” alert appears. This means the hard drive is not detected due to bad sectors on the platters, the software or the read heads.
- The drive is not recognised. The computer is unable to detect the hardware.
What causes a firmware failure?
A firmware issue can stem from a malfunction of the platters or the electronic board. Physical shocks, natural wear of the platters and read heads, or a malfunctioning read head can all lead to firmware failures.
The electronic board (PCB) can be damaged by voltage spikes at start-up or during use, as well as dust, heat and humidity.
Is data recovery always possible after a firmware failure?
Data recovery is possible as long as the individual modules are not permanently damaged and the firmware is not locked. The physical integrity of the location of the damaged modules must be sound. In this case, repairing the drive only serves the purpose of data recovery.
Generally without irreversible consequences, this type of failure means you need to call on a data recovery professional.
The dangers of DIY repair using data recovery software
Following a firmware failure, you use the drive without being able to access your files. Some people may be tempted to try to fix the problem themselves, using data recovery software. Ultimately, it is precisely this kind of attempt that can lead to permanent data loss. In the event of a more serious mechanical failure, the software will force the read heads to pass over the surface of the platters, risking scratching them, and thus making it impossible to access the data stored on them.
What should you do in the event of a firmware failure?
If you think your hard drive has a firmware failure, you should immediately shut down your operating system. This will help protect against the risk of scratching the platters. If the failure turns out to be mechanical in origin, this would worsen the damage already caused. In any case, the drive should be kept in a safe place to protect it from shocks. We then recommend that you get in touch with our lab to begin the data recovery process.
Why go through a data recovery professional?
It is recommended to go through a data recovery professional in order to minimise the risk of data loss.
Working with a professional guarantees that you are dealing with recognised experts and helps avoid data loss. With over fifteen years of experience, Chronodisk’s engineers develop their own methods and tools. The most severe mechanical cases require processing in a cleanroom, as the slightest speck of dust could damage the magnetic ferrous layer of the hard drive. Nothing more can be done for drives that have been opened in open air by individuals.
Recovering data is similar to an organ transplant and most often takes place in a cleanroom. The first step is to find a drive compatible with the faulty hard drive. The goal is to transplant electromechanical components from one to the other. The next step is duplicating the repaired drive onto a healthy hard drive. The file systems and information are then finally extracted and recovered in the technical room onto an external hard drive.
