Common Hard Disk Issues

Before learning how to repair a hard disk that doesn’t work properly, you should figure out the condition of your disk – is it physically damaged, a logical error, or a firmware fault? Below are common disk errors and how they manifest themselves:

Logical Errors

Problems occur in the software or data on the hard disk, not the hardware itself, such as virus infections, malware, corrupted system files, bad sectors, etc., leading to data loss, file system corruption, performance degradation, or boot failure.

Firmware Issues

When firmware gets corrupted, it is usually accompanied by obvious telltale signs, such as the drive slowing down in reading and writing data, the clicking noise happening when the read head is seeking the right sector, the operation system can’t recognizing the hard disk and showing “Disk Unknown/Not Intialized” message, etc.

Physical Damage

Physical damage is also a common cause of hard disk failure, including high temperature, water ingress, falling from a height, extrusion, etc. Unfortunately, if a hard disk has suffered severe physical damage, especially to the components but not appearance, it is virtually impossible to recover stored data.

How to Prevent Data Loss on a Hard Disk

As we mentioned earlier, disk problems can be categorized into three dimensions: physical damage, logical errors, and firmware issues. So we can also think of some preventive measures as follows:

Keep your hard disk in a safe place: Make sure your hard disk stays at a secure physical location, which is far away from high temperatures, your drinking cup, high places where it can be easily dropped, etc.

Periodically back up your important files: Backing up your data frequently can help prevent data loss, such as backing up once a week or uploading important files to the cloud drive. Even if you have a hard disk failure, backups will minimize the impact on your workflow.

Choose a trustworthy hard disk: Hard drives vary in quality, so choosing a well-known and trustworthy brand may reduce the risk of firmware issues. Seagate, WD, and Toshiba may be trusted companies.
