Most users face hard drive failure but don't worry. Hard drive failure does not mean the end of the hard drive's life. On the contrary, you can still use it, but you need to know that this disk may crash at any time.

Therefore, when receiving a hard disk error warning, the most important thing to do is to back up all data currently on the disk. After completing the backup, you need to diagnose your disk health, analyze the cause of the disk failure, and resolve the hard drive failure.

This article will provide you with detailed guidance. First, we need to perform a disk health check on the current disk. How to do? Please continue reading.

Stage 1. Perform a Disk Health Check - 2 Ways

EaseUS Partition Master Professional provides two functions, "Disk Health" and "Surface Test," to help you confirm the current disk health. Through these two functions, you can clearly see the current health score of your disk and the number and distribution of bad sectors. Now, install the tool and follow the two instructions below.

Way 1. Run Disk Health Check

By checking the current disk temperature, Power On Hours, Power on Count, and other indicators, EaseUS Partition Master can determine the approximate remaining life of your disk. It can issue timely warnings if temperature and other health indicators are abnormal. Here's how to use this tool:

Step 1. Launch EaseUS Partition Master and click the blue arrow to activate the "Disk Health" feature under the "Discovery" section.

Step 2. Select the target disk and click the "Refresh" button. Then, you can see the health condition of your disk.

Pay attention to the "Status" section, and check the list below to verify if your disk is in good condition:

  • Good: The disk is healthy and running with a nice performance.
  • Bad: The disk is unhealthy and will fail at any time. 
  • Unknown: The disk is already damaged, and EaseUS Partition Master can't detect it at all.

🚩If the result is "bad," back up your data and OS first; be prepared because you may need to recover data or boot from another disk.

🚩If the result is "unknown," send it to repair or replace it with a new one.

Way 2. Check Bad Sectors

Bad sectors will also gradually accumulate during use and cause disk failure. EaseUS Partition Master can help you locate bad sectors on the disk by running a disk surface test.

Here's how:

Step 1. Open EaseUS Partition Master. Right-click the disk that you want to check, and then click "Surface Test".

Step 2. The operation will be immediately performed and all bad sectors will be marked as red.

Bad sectors will be marked as "Red" during the test. If many bad sectors show up, you need to pay attention and back up your data first. The accumulation of bad sectors will cause a hard drive to fail.

Through the above two methods(Check hard drive health and check for bad sectors), you can know the possible remaining life of the failed hard drive. Based on this result, timely replacement of the hard drive or migrating the system from the failed hard drive is the right choice for you.

Stage 2. How to Fix Hard Drive Failure - 2 Options

Hard drive failure may result in data loss at any time. Moreover, if your system disk fails, your computer may freeze or experience startup errors. Therefore, to avoid these situations, we will tell you how to replace the system disk or migrate the operating system to another disk in this section.

Option 1. Clone and Replace the Failing Hard Drive

Prepare your new hard drive and connect it to your current computer. Before you replace the hard drive, you need to clone the existing data or system directly to the new hard drive. Otherwise, you will lose all your personal data and system settings, etc. Using cloning software - EaseUS Partition Master, you can clone this crashing drive without any manual data transfer.

  • Done means you want to make the changes later.

Compared with cloning the entire system disk, system migration is relatively simple and time-saving. Moreover, with EaseUS Partition Master, this process will be even simpler. With just simple clicks, you can migrate your system off this damaged hard drive.
