Failure of Printed Circuit Boards or PCB is one of the leading causes of hard drive failures. This is a type of advanced hard drive failure. If your hard drive is facing a similar issue and you are wondering after the PCB failure, “how to recover data?” don’t try to fix it yourself after it might be difficult to solve the issue without professional help. Moreover, mishandling of PCB failure can damage your hard disk. It can make data recovery almost impossible. Why? Because the PCB is one of the most important parts of a hard drive. It controls everything that the hard drive does.
Let’s understand everything about PCBs and how you can recover data after PCB failure?
What is PCB Failure?
Here is how hard drives work. They consist of spinning disks whose surfaces are magnetic. A moving arm inside the hard disk uses an electromagnet. It changes the fields associated with each cell. These fields are used at a later stage. They read and process the stored data.
All these functions are made possible by Printed Circuit Boards or PCBs. This includes decoding, encoding, reading, and writing actions. There are many ways in which we can include PCBs in the hard drive. Some designs feature a single-board layout. Other designs can also include many PCBs, split PCBs, or bottom-mounted PCBs.
PCB Failures occur when the drive becomes inaccessible. This might be because the PCB has developed a defect and has stopped working. Interference from an external agent can make this possible.
Types of PCB Failure Analysis Tests
In the PCB failure testing, there are many tests that required for identifying the defects in the device. We perform a PCB analysis based on the damage the PCB has taken. It also depends on the type of recovery process required. The following tests have the highest success rate. Professional data recovery experts also make use of these steps.
1. Micro-section analysis
This PCB testing method is used to investigate the following:
- Thermo-mechanical failures.
- Component defects.
- Opens or shorts.
- Processing failures due to solder reflow.
- Raw material evaluations.
A removed sample from the analysis provides the expert with a technique. This isolates the electronic component in question.
2. Solderability testing
This type of testing improves the robustness of the surface. Also, reliable solder joints can be formed again. Technicians use this to understand the effect of stored solder components on PCBs. It can also tell the reason for the fault. This method helps to investigate:
- PCB coating evaluation.
- Solder evaluation.
- Flux evaluation.
- Quality control.
3. Contamination testing
Contamination of the hard drive can also lead to many issues. This includes corrosion, degradation, metallization, and rapid deterioration of wire connections. Common sources of contamination include human byproducts, handling, flux residues, and reaction products. Tests under this head include the handling of:
- Copper etching liquid.
- Hot air levelling fluxes.
- Electrolytic solutions.
- Water-soluble soldering.
Symptoms of PCB (Printed Circuit Board) Failure on Hard Drive
Look for these signs to check for PCB failures:
- The hard drive has become completely unresponsive.
- A smoky smell or burning smell is produced especially when the computer is on.
- The temperature of the drive shoots up even under nominal usage.
- The computer reports incorrect status information of the hard drive. This can range from incorrect storage space to partition schemes.
- The system prompts you to format the drive.
- It might be taking a lot of time to open files and folders. Or even write new data to the disk.
- Strange errors might crop up in files.
How to Prevent PCB Failures?
You can avoid PCB failures if you observe the health of the hard drive on a regular basis. Also, undertake the following checklist:
- The layers of the PCB should be properly aligned. This will avoid hard disk issues. And short circuits or incomplete open circuits. Hence, any physical damage to the drive can trigger this. It should be taken care of.
- Physical damage can also lead to a broken component package. This makes the hard drive more susceptible to excessive heating. Manufacturing flaws are a major reason for this.
- Power surges that cause the voltage to shoot up. This can also end up harming the hard drive.
PCB Failure – How to Recover Data with Professional Data Recovery Service?
PCB data recovery is a complex process. It should only be left to data recovery experts. Stellar Data Recovery can be the best solution for your hard disk recovery woes.
PCB recovery is complex because you cannot just replace an old PCB for a new one. Because the circuit boards are uniquely identified by the hard drives. Specialized equipment is needed to solve the issues. Practical knowledge of PCB circuits is also required.
Data Recovery experts at Stellar are backed by decades of experience. We check all possible hard drive failure reasons. Once the reason is figured out, a firmware transfer of the PCB is undertaken. We also perform logical data access and checks for bad sectors.
Apart from this, Stellar Data Recovery can also handle all other major hard drive recovery cases. This includes the following:
- Data Deletion.
- Virus Attack.
- Power Surge.
- Clicking noise coming out of the drive.
- No sensation in the drive.
PCB failure can strike any hard disk anytime. The biggest problem with this issue is that it can be impossible to recover your data yourself. You need to avail professional help. If the PCB of your hard drive is damaged, get in touch with Stellar to recover your data.
