Whether through general wear and tear, human error, software bugs or malware, or unforeseen damages caused by accidents, hard drive failures can happen for any number of reasons. But regardless of the cause, hard drive failures guarantee a major headache for those involved, especially if there is no data recovery initiative in place.

Signs of Hard Drive Failure

Hard drives are susceptible to failure in a number of ways, so the symptoms of a failing hard disk can vary. Some of the most common signs include:
- Unusual or excessive heating
- Repeated read or write disk errors
- Frequent computer crashes or freezing
- Folders and files cannot be accessed
- Disappearing data
- Hard drive is powered but cannot perform routine functions
- Hard drive is powered but misrecognized by computer or displays nonsensical characters
- Hard drive can be accessed but lags or appears to “hang”
- Motor working but hard drive not recognized by computer
- Hard disk freezes during booting
- No sounds due to motor freeze
- Computer notification/error log reads Cyclic Redundancy Check (CRC) errors
- Unusual noises, including unexplainable clicking, screeching, or grinding

Types of Hard Drive Failure

Mechanical Failure

Hard drives are one of the few mechanical components of a computer, so as with any mechanical device, they are prone to the effects of wear and tear, although mechanical failure can also be caused by hard impact. For especially older hard disk drives, mechanical failure is a strong possibility, with failures of essential functions like the read/write head and motors. Frequent computer crashes or freezing and unusual noises can be signs of mechanical failure.

Electrical Failure

A hard drive uses electricity to communicate, so any failures of the electronic circuitry of the read-write head and the printed circuit board (PCB) can lead to loss of access to data. Power voltage surges, caused by damaged power lines or lightning strikes, can cause electrical failure. If the hard disk is powered but cannot perform routine functions, then an electrical failure may be the source of the problem.

Logical Failure

Any non-physical failure of the hard disk’s software systems can result in logical hard drive failure. Logical failures can result from any number of corruptions to the hard drive data, including malware, corrupted files, software viruses, improperly closing a program, accidental computer shutdown, accidental deletion of files essential to hard disk functions, human error, and more.

Bad Sector Failure

Hard drives read magnetic data on the rotating platter, but because the magnetic alignment on the platter is not failproof, any misalignment of the magnetic media can result in a sector of the platter becoming inaccessible. Bad sectors are common to most hard drives and are difficult to eliminate, but they can usually be contained in the drive service area. However, over a long period of time, additional bad sectors can develop and lead to the dreaded head crash.

Firmware Failure

The firmware of a computer is a type of software that performs the disk checking and maintenance functions on a hard drive. It is what allows the hard disk to communicate with the computer. Typically located on the PCB board as well as on data platters, any corruption to the firmware can result in a breakdown of communication, even when all mechanical and electrical functions are operational.

Most Common Causes of Hard Drive Failure

The various types of hard drive failure can sometimes occur due to general wear and tear, manufacturer defects, human error, malware, and viruses, or freak accidents. The most common causes of hard drive failure are briefly listed below:
- Power surges from lightning strikes, power failures or damaged power lines
The Many Causes of Power Failures - Mid-America Engine
- Hardware overheating as a result of inadequate cooling or ventilation systems
empty
- Water damage from flooding, spilt liquids or moisture seeping into the hard disk case
empty
- Physical damage caused by dropping the hard drive, or bumping into or hitting it
- Corrupted files due to accidentally and unexpectedly shutting down a computer, improperly closing programs, or installing infected software
- Malware, viruses, and software bugs
empty
- Human error, which can result from tampering with files essential to the hard disk and includes accidentally deleting files necessary for the disk to function

How to Prevent Hard Drive Failure

Hard drive failures can be frustrating, but routine maintenance can help prevent common issues. Here are some steps to safeguard your hard drive:
1. Ventilation and Cooling
  • Proper ventilation is crucial. Ensure that fans and ventilation grids on your computer are not blocked.
  • If your computer overheats excessively, turn it off and allow it to cool down.
  • Persistent overheating? Seek professional repairs.
2. Power Surges
  • Unplug your computer when not in use to prevent power surges from damaging the hard disk.
  • If unplugging is inconvenient, use a surge protector while keeping the computer plugged in.
3. Regular Cleaning
  • Dust can penetrate the hard disk casing and obstruct the read-write head, causing a head crash.
  • Routinely clean your computer and its surroundings.
4. Malware Protection
  • Install reliable malware and virus scanners to prevent harmful downloads.
  • Choose from various antivirus options available.
5. Maintenance Scans
  • Perform routine checks and scans to ensure correct disk operation and defragment storage files.
  • While they may not prevent all failures, these scans can reveal system errors.

What to Do and What NOT to Do

Depending on the severity of the hard drive failure, consider the following:
You Should:
  • If your system lags or shows signs of failure, back up important files immediately.
  • Regularly back up your computer to avoid data loss.
  • Note that even the best recovery software or professional services may not retrieve all files.
Unusual Noises or Inaccessibility, If your hard drive makes strange noises or becomes inaccessible, you Should NOT
  • Restart, hard boot, or force shut down the computer.
  • Instead, seek professional assistance for hard drive recovery.
