Computer users employ hard drives on a daily basis and store their valuable information there. When the data becomes inaccessible, we all look for different and easy ways to fix the hard drive failure.
The internal and external hard drives contain hardware and software components, and each of them is very important for the hard drive’s proper work. Some of the crucial ones include:
The Printed Circuit Board (PCB). The PCB is required to operate the motor and control data flow. The PCB is often connected through a SATA, IDE, SCSI, or SAS connector.
Spindle. The spindle rotates the platters as needed while maintaining their position. The spindle keeps the platters at a constant distance apart so that the read/write arm can gain access. The RPM (revolutions-per-minute) rating determines how quickly data can be written to and read from the hard drive. Internal desktop drives typically spin at 7,200 RPM, though faster and slower speeds are available.
Read/Write Arm. The read/write arm guides the movement of the read/write heads, which convert the magnetic surface into an electric current to read and write on the disk platters. The arm, also known as the head arm or actuator arm, ensures that the heads are in the proper position based on the data that needs to be accessed or written. Each platter side typically has one read/write head that floats 3 to 20 millionths of an inch above the hard drive’s platter surface.
Actuator. The actuator, also known as the head actuator, is a small motor that receives instructions from the drive’s circuit board and uses them to manage the movement of the read/write arm and regulate data transfer to and from the platters. It is in charge of ensuring that the read/write heads are always in the correct position.
The Firmware: Firmware is a computer program that is hard-coded into the internal hard drive and contains the hard drive’s basic operational storage programming. Another way to think of firmware is as a software middleman, allowing your hardware to communicate with software (i.e., Windows operating system, etc). For a hard drive, the firmware is a program that governs the behavior and factory settings, even the identity, of that drive. Any drive that leaves the factory and is in use in a computer or server has firmware installed on it.
How Hard Drive Works and Fails
The motor is activated and begins to rotate upon powering up. The reading heads block is currently parked in a specific parking zone. This demagnetized zone can be on the plates (towards the center) or on a ramp.
When the motor reaches its maximum speed, air reaches the platters to transport the read/write heads and keep them floating without even touching the HDD platters. To read and write data, read heads can be launched onto platters. The heads eventually return to their initial location. When any of these components get damaged, or the platters fail due to wear-and-tear, the HDD user losses access to his data.
Hard drive Failure – Fixing Solutions
Hard drive hardware failure can affect the proper functioning of the drive. This failure may concern one or more components of the hard disk: mechanical component, electronic component, or Firmware component. We, therefore, speak of a hard disk that is physically inaccessible or a hard disk not recognized by the computer.
A logic failure may accompany this failure. The best-known examples of hardware failure: are a hard disk no longer spins, a fallen hard disk, and a hard disk that has suffered a power surge; among the examples less known to the general public, an unrecognized hard disk due to aging and wear of the hard disk, a hard disk locked by a password. Strangely it is a hardware failure because due to this locking from an HS hard disk, recovering data may be inoperative.

Possible causes of hardware failures
- If a hard drive component fails, repairing a damaged internal hard drive sometimes requires replacing the failed hard drive components.
- In the event of serious read/write errors beyond the Firmware’s ability to manage, repairing the internal hard disk is a fictitious operation because it eliminates the signs of the symptoms of the failure and not the causes. This may be temporary hard disk backup time physically.
- Repairing a faulty, factory-installed hard drive is problematic because hard drive repair tools do not take care of these faults. Sometimes, the manufacturer may provide information to help data recovery professionals eliminate this defect.
- Repairing a damaged internal hard drive in some cases may not be possible if the degradation of the hard drive is irreversible due to excessive temperatures or humidity, flooding, fire, etc.
- The repair of a hard disk drive having suffered a shock or a fall only replaces the block of read heads if the state of the platters allows it. Otherwise, the disk is out of service forever.
Hard drive repair options
- Repair of the hard disk failure due to physical damage: In such a case, the hard disks are suffering from physical damage, and in most cases, damage users’ data with each spin. When recovering such data loss cases, it is necessary to have identical or compatible components and advanced tools and operate in the ISO Certified Class 10 Cleanroom. Professionals of our data recovery company have required hardware and tools to ensure the maximum data repair results in such data loss scenarios.
- Hard disk repair failed due to logical damage: If the hard drive failed because of logical damage, it does not require physical inspection. However, it still requires professional data recovery services to ensure maximum results and no data leak opportunities.
Recovering data from a hard drive by yourself is not safe, as the success rate of the recovery attempt is very low. And we found that the 2nd attempt reduces the chance of successful data recovery by 80%.
Each data loss scenario is unique. PITS technicians have generated specialized hard drive recovery software and hardware, allowing us to provide customized hard drive data recovery solutions for all common and catastrophic data loss scenarios.
Our engineers provide successful hard disk recovery to those cases, which other service providers have declared permanently lost. We maintain a 99% success rate by operating in ISO Certified Class 10 Cleanroom, using state-of-the-art tools.

In addition, our experienced technicians have years of experience recovering important files from different data loss scenarios.
Data loss scenarios we recover data from:
- BSoD Error Message
- Bad Sectors
- Physical Damage
- Malware and Virus Damage
- User Error, Accidental File Deletion
- Data Corruption
- Water Damage
- Power Supply Failure
To name a few, these are some of the common hard drive failure scenarios our customers face with.
