2. Recovering Data from a Corrupted External Hard Drive

How Can I Recover Data from a Faulty External Hard Drive?

When your storage device suddenly stops working, the most pressing concern is how to recover your data. Here are two methods to address this issue effectively:

2.1. Method 1: Using a Different USB Cable or PC

Will connecting my hard drive to another computer help?

Yes, if you’re unsure whether the device has issues, connect it to a different USB port or PC. If the drive is readable, you can access your data. If not, proceed to check its status in Windows Disk Management.

Step-by-Step Guide:

1. Right-click on “This PC” and select “Manage.” Under the “Storage” section, click “Disk Management.”
   Alternatively, press Windows + R, type diskmgmt.msc in the “Run” box, and press Enter.
2. Right-click on the SSD partition and select “Change Drive Letter and Paths…”.
3. Click the “Change” button among the “Add,” “Change,” and “Remove” options, and then select a drive letter from the list. Click “OK” to assign a new drive letter to the problematic hard drive.

2.2. Method 2: Using Hard Disk Recovery Software

Can data recovery software retrieve files from a failing drive?

Yes, as long as your hard drive is detected by Windows Disk Management, reliable hard disk recovery software can help you retrieve data with just a few clicks.

Software Recommendation:

EaseUS Data Recovery Wizard is an excellent tool for recovering lost data on all storage devices under Windows 10/8/7.

Step-by-Step Guide:

1. Download and Install: Download and install EaseUS Data Recovery Wizard.
2. Select the Drive: Run the software and select the drive on the hard disk where you lost or deleted files. Click “Scan” to begin scanning.
3. Scan for Lost Data: The software will scan the entire drive, finding all lost files, including existing and hidden data.
4. Preview and Recover: Preview the files you want to recover and click “Recover” to save them to a safe location on your PC or another external storage device.

According to a case study by CAR-REMOTE-REPAIR.EDU.VN, using professional data recovery software significantly increases the chances of successful data retrieval from damaged hard drives.

3. Restoring Corrupted System Files from an External Hard Drive

How Can I Restore Damaged System Files?

Lost or corrupted system files can cause unusual symptoms on your hard drive. This typically happens when there is an issue during file storage.

Step-by-Step Guide:

1. Open the “Start” menu, type cmd, and press Enter to run the Command Prompt.
2. Type chkdsk g:/f (if the external hard disk is drive g) and press Enter.
3. Type sfc /scannow and press Enter.

Once the repair process is complete, you’ll see the message “Windows Resource Protection did not find any integrity violations” if no corruption is found. Otherwise, Windows will repair them automatically.

4. Repairing a Corrupted External Hard Drive

How Can I Fix a Corrupted External Hard Drive?

This section will show you two methods for formatting a corrupted external hard drive to return it to normal. Before proceeding, understand which hard drive issues formatting can resolve.

What Problems Can Formatting Solve?

Formatting can address common hard drive issues such as “Disk is not formatted, do you want to format it now?” or when the hard disk does not appear and is displayed as RAW. It can also scan and repair bad sectors and remove viruses or malware.

4.1. Method 1: Formatting a Corrupted Hard Drive

Step-by-Step Guide:

1. Connect the problematic external hard drive to your PC.
2. Right-click the device and select “Format.”
