HARD DISK DATA LOSS SCENARIOS
A hard drive on a computer can fail due to either physical or logical damage. There are a variety of ways your device can experience data loss. Some common data loss scenarios include:
PHYSICAL FAILURE:
- Clicking or grinding noises from the hard drive
- Water or fire damage
- Read/write head failures
- Drive not recognized by BIOS
What to Do If Your Desktop is Failing
If you notice any signs of failure on your desktop, the best course of action is to immediately power it down. This minimizes the risk of further damage and data loss. Do not attempt to open the hard drive yourself or perform DIY recovery, as opening the drive outside of a clean room environment can introduce dust particles that may scratch the platters and cause permanent data loss.
Avoid using data recovery software on your own. While it might seem like a quick fix, such software can overwrite your data during its attempts to boot or recover files, putting your important information at greater risk. Additionally, DIY recovery software often cannot recover all critical files, especially in cases of physical damage.
The safest and most reliable option is to power down the system and contact a professional data recovery specialist. They have the expertise and tools to safely recover data from failed hard drives without further risk of loss.

External Drive Recovery
External hard drives (HDDs) are commonly used as secondary storage and a reliable backup solution. Portable and easy to use, external hard drives typically consist of a standard 2.5″ or 3.5″ hard drive housed in an enclosure with an external port that connects to a computer or other media devices, most commonly via USB.
When an external hard drive fails or becomes damaged, PCPrompt Data Recovery offers qualified recovery experts and industry-leading external hard disk data recovery services.
Some of the external hard drive manufacturers we work with include:
- Seagate
- SanDisk
- Western Digital
- Toshiba

- Sony, and many others
There are three basic types of external hard drive failure that can result in data loss:
Physical Failures in External Hard Drives
External hard drives contain internal components that operate at high speeds, making them prone to mechanical failure over time. These failures can result in severe data loss. Some of the common physical issues that lead to data loss include:
Read/Write Head Crashes: The read/write heads hover just above the surface of the drive’s platters. If the heads make contact with the platters, they can damage the surface and cause data loss.
Spindle Motor Failure: The spindle motor controls the spinning of the hard drive platters. If the spindle locks up or fails, the drive will be unable to spin, and the data becomes inaccessible.
Actuator Arm Malfunction: The actuator arms move the read/write heads across the platters. If these arms fail to function properly, the drive may not be able to read or write data correctly.
Unusual Noises: Sounds like grinding, clicking, or beeping typically indicate a problem with the read/write heads or internal components, such as a stuck actuator arm or motor failure.
These types of physical failures often require specialized recovery techniques to access the data, and professional help is typically needed to avoid further damage.
Electronic Failures in External Hard Drives
Electronic failures can render an external hard drive completely inoperable or cause it to display error messages, depending on which electronic components fail. These failures are just as serious as physical damage and should only be handled by experienced data recovery professionals to avoid further damage. Common causes of electronic failures include:
Faulty Power Supply: Issues with the internal power supply can prevent the drive from receiving the proper voltage, causing it to fail to power up or function properly.
Power Surge or Voltage Fluctuations: A power surge, often caused by lightning or faulty electrical circuits, can damage the drive’s internal electronics. This can result in an inability to power the drive on or cause permanent electronic failure.
Unstable or Improper Power Connections: Connecting the hard drive to an ungrounded or unprotected power outlet (i.e., not using a surge protector) can expose it to power spikes, increasing the likelihood of electronic failure.
Faulty or Failed Circuit Boards: A malfunctioning drive circuit board, which controls the communication between the drive’s internal components, can prevent the hard drive from functioning correctly or make the data inaccessible.
These types of failures often result in the drive being completely unresponsive or showing error codes, and it’s essential to consult a professional data recovery service for proper diagnosis and recovery.
Logical Failures in External Hard Drives
Logical failures occur when data on an external hard drive is lost due to issues that don’t involve physical damage to the hardware. These failures can be caused by software-related issues, file system corruption, or human error. Common types of logical failures include:
Virus or Malware Attacks: Malicious software can corrupt the drive’s data or make it inaccessible by damaging the file system or individual files.
Accidental Deletion: Files or entire directories may be unintentionally deleted by the user, leading to data loss. In many cases, this can be recoverable with the right tools, especially if the data hasn’t been overwritten.
File System Corruption: If the file system becomes corrupted—due to improper ejection, software crashes, or bad sectors—your computer may no longer be able to recognize the drive or access the data.
Drive Not Recognized by Host System: Sometimes, the external hard drive may not show up in your computer’s file explorer, either due to logical issues like partition corruption or problems with the drive’s file system.
These issues typically don’t involve hardware damage, so in many cases, data recovery can be performed without physically opening the drive. However, specialized software or professional recovery services may be required depending on the severity of the logical failure.
Laptop Data Recovery Services
When a laptop is damaged, it can be a stressful situation. You may have important files, documents, photos, and other data stored on the device that you need to access. Fortunately, there are several ways to recover data from a damaged laptop that might otherwise seem lost forever. In this guide, we’ll discuss different methods of data recovery from damaged laptops, so you can get back the valuable information you need.
Laptops are designed to be portable, and many models come with built-in features intended to protect the hard drive and other components from impact damage. Some modern laptops even offer a degree of water resistance, while specially designed industrial laptops use near-indestructible materials to minimize the chances of hardware failure.
However, despite these protective features, laptops remain vulnerable to certain types of damage. Impact, drops, spills, and even prolonged exposure to heat can lead to hardware failures and data loss. While weather-resistant and rugged designs offer some protection, they do not guarantee complete immunity from damage or data loss.
Common Causes of Laptop Data Loss
Choosing a Reliable Data Recovery Provider
When your laptop fails, you need quick and professional help to regain access to your most important files. Sudden hard drive issues, software errors, or other failures can prevent you from accessing personal or business data. When reconstructing the missing information isn’t an option, a reliable data recovery provider can help you recover your data and get back on your feet.
If you cannot access the data on your laptop, it’s important to act quickly. Immediately turn off the laptop to prevent further damage to the hard drive. Continuing to use a malfunctioning device can worsen the issue and potentially make recovery more difficult.
If your laptop is unresponsive, you can usually shut it down safely by holding the power button for several seconds until the screen turns off. Avoid attempting to disconnect the hard drive unless you are experienced, as this can be a delicate procedure. If you’re unsure or if removing the hard drive could void your laptop’s warranty, it’s best to seek professional assistance right away.
