A hard drive failure happens when your computer’s storage device stops working properly. This can cause slow performance, strange noises, corrupted files, or even complete data loss.
Common warning signs include:
- Clicking or grinding noises
- Very slow performance
- Frequent crashes (Blue Screen of Death – BSOD)
- Corrupted or unreadable files
Hard drive failures are usually caused by mechanical wear, physical damage, overheating, or power surges. When you notice these signs, the most important step is to immediately back up your data and stop using the drive to prevent permanent loss.
Now let’s understand everything step by step.
