6 Common Reasons For Data Loss in a Mac Device

Data loss is a typical system failure suffered by computer users today. Though Mac systems are known for their reliability and safety, data loss can happen on these devices too. There are a few reasons which can lead to data loss in a hard drive. Learning about these reasons will help avoid the possibility of data loss in the future.

Physical Issues

A Mac hard drive is prone to physical damage like drops, water damage, etc. All this can result in the crash of the drive head and lead to the failure of the spindle motor. Physical damage on the hard drive may lead to difficulties in accessing the data therein, thus require Mac recovery.

Corrupted Files

Abrupt System Shutdown due to electricity failure or forced restart can cause corruption in system files. Thus, rendering the hard drive inaccessible. Also, irregularities like Shutting down a PC unethically, use of faulty or malicious apps, the accidental closing of running programs, and power surges can contribute towards corruption in the system files.

Heat

Due to poor ventilation or improper CPU fan, a system could be heated to its peak point. This may result in the sudden crashing of the hard disk or severe damage to the hardware of the computer. This effect is often irreversible in nature.

Manufacturer or Firmware Faults

This issue occurs with the new hard disk that prevents it from functioning correctly. It can happen a few days post-purchase.

There is a high possibility that a hard disk is faulty due to the manufacturer’s negligence. Such hard drives are mostly sent to the customer without any prior testing.

Electronic Issues

Mac hard drives are susceptible to power failures. When a Mac Device suffers a power surge, the electronic parts in the hard drive may be damaged. This an occur when the components in the hard drive are of inferior quality. Electronic failures generally lead to issues in the transient voltage suppressor, inductor or micro-controller chip.

Logical Issues

A range of Mac hard drives use Hierarchical File System that is quick and more efficient as compared to other file systems. This file system also has its vulnerabilities. Following are the type of issues with the HFS file system that can result in data loss.

  • Catalog File Corruption
  • Failures in Re-sizing Volumes
  • Journal File Corruption
  • Accidental Human Errors

What is the best course of action to prevent data loss?

Backing up files is the safest way to prevent data loss due to hard drive failure. Hard drive failure can occur anytime without warning due to power surge, virus attack, damaged blocks, corrupted OS files such as boot.ini, NTLDR, ms-dos. Sys etc.

Conclusion

Just like its Window-based counterpart, data loss due to hard drive failure also occur in Mac Computers. Regular data backup remains the most effective method of preventing unexpected loss of data.

The use of data recovery tools is another way of restoring lost data, but having a backup of the lost data will ensure the system is restored within a short time in the event of loss.
