If, while using your Mac, you notice that the system freezes frequently, folders disappear, and the computer becomes slow, these signs may indicate that your hard drive is corrupted.
This issue can be caused by physical damage to the drive, virus infections, firmware corruption, or disorganized data due to file system errors.
This problem can become a real headache, as its main consequence is data loss — since access to your files may be compromised when the drive is corrupted.
But don’t panic.
In this article, we’ll show you how to identify the warning signs of a failing hard drive, how to prevent this issue, and how to recover your data if your drive is already corrupted.
What are the symptoms of a corrupted hard drive on Mac?
Storage devices — especially hard drives — are more prone to failure due to how they are built.
This is because hard drives have moving mechanical parts, and vibrations or sudden impacts can damage the disk.
Here are some common warning signs:
- Applications closing unexpectedly;
- Your Mac becomes unresponsive;
- Files that won’t open or respond;
- Difficulty moving files;
- In more severe cases, the Mac may fail to boot.
How to prevent hard drive corruption on macOS?
To prevent hard drive corruption, it is important to keep your device away from liquids, dust, and heat, and avoid impacts during use.
It is also essential to keep regular backups and properly shut down your system.
Shut down your Mac properly
Avoid forcing shutdowns. Always use the Apple menu and click “Shut Down”.
This ensures all processes are completed correctly and prevents file system corruption.
Monitor your hard drive
Regular monitoring helps detect problems early.
If you notice unusual behavior, you can act quickly and prevent data loss caused by logical errors or bad sectors.
Use the First Aid feature in Disk Utility to check your drive.
Create regular backups
Use Time Machine to back up your data.
With a Time Machine backup, you can restore your system if the drive fails.
How to repair a corrupted hard drive on Mac?
There are several ways to recover a corrupted hard drive on Mac. Here are the main ones:
Repair using Disk Utility
Open Terminal and run:
diskutil repairVolume /Volumes/[Drive Name]
Replace “Drive Name” with your drive’s name and press Enter.
You can also use the graphical interface via the First Aid option.
Use the FSCK command
This command checks and repairs file system errors.
On older Macs, use Single User Mode (Command + S). On Macs with T2 or M1 chips, use Recovery Mode.
Run:
/sbin/fsck_hfs -fy /dev/[partition number]
Repeat until the system reports that the volume is OK.
Use data recovery software
Tools like Disk Drill can help recover files.
However, these tools do not fix the root cause of the problem.
