Part 3. How to Repair the Corrupted External Hard Drive

A corrupted external hard drive is a wide common situation and thousands of people facing it every day. When you fail to access your external hard drive, you need to follow the solutions below to check and fix it:

  • Check the power supply and connection errors. It's likely that your device has a separate power source. Therefore, checking the power supply will be important.
  • Try another USB cable. Maybe there's something wrong with the old one.
  • Use antivirus to scan your drive if the external hard drive has viruses on it.
  • Run SFC (Open "Command Prompt" and enter sfc /scannow). It helps fix the damaged or missing Windows system files that may cause drive corruption.

Run CHKDSK to Fix the File System Errors (Recommended)

If the three simple ways are unable to help, my suggestion is to run CHKDSK to fix the file system errors on the external device. CHKDSK command prompt checks the file system and file system metadata of a volume for logical and physical errors. 

Step 1. In the Search Window, type cmd. On the search result, right-click on the Command Prompt and select "Run as administrator".

Step 2. Type the command:

Click to copy

Here you should replace E with your drive letter.

If you don't have any technical know-how and want to minimize data risks, using third-party software could be a better choice. The Command line is suitable for computer professionals since wrong commands can cause severe problems. Therefore, we strongly recommend you to try an automatic command line alternative.

EaseUS Tool M is a practical computer fixing tool that is safe and light-weighted. It's a perfect alternative to CHKDSK command. Use this one-click tool to solve your computer issues.

Frequently Asked Questions

1. Why choose EaseUS Data Recovery Wizard?

"EaseUS Data Recovery Wizard is the best we've seen. It's far from perfect, partly because today's advanced disk technology makes data-recovery more difficult than it was with the simpler technology of the past, but it's fast and efficient..."PCMag

"The first thing you'll notice about EaseUS Data Recovery Wizard Pro is that its interface is very clear and uncluttered, with only a small collection of self-explanatory controls. You won't find lots of extra options hidden in a system of hidden menus, either; what you see really is what you get."techradar

"Recover lost files, even after deleting a partition or formatting your drive."Macworld

2. Why cannot I recover 2GB data for free?

It is recommended to check the version installed is Free or Trial because they are different versions.

Trial has data preview function but cannot save any files, while the Free version enables to recover 2 GB files. The default free space is 500 MB and you may share the product on social media to get another 1.5 GB.

3. Why cannot the recovered files be opened?

A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.

If the files with original file names and folder structures cannot be opened, one possible reason is the corrupted directory info. There is still a chance to recover the data content with the RAW Recovery method in our software.

4. Why isn't it suggested to recover the files back to the original drive?

The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss. So you should prepare another disk to save the files.

5. How can I check whether my data is recoverable or not before purchase?

The Free version helps you save 2GB files to better verify the recovery quality of our product before purchase.

6. How long does it take to scan the drive?

It strongly depends on the capacity of your hard drive and the performance of your computer. As reference,most drive recoveries can be completed in around 10 to 12 hours for a 1-TB healthy hard drive in general conditions.
