How to Recover Data from the Corrupted External Hard Drive
When your storage device suddenly stops working, the most important thing that crosses our mind is how to recover data or files from it. Below, you'll find two methods to fix this issue.
If you are not sure whether the device has an issue, you can connect it to a different USB port or even a different PC to see whether it gets detected or not. If the drive can be read, then you can use your data on the external hard drive.
In case the hard drive cannot be detected on the other computer, check its status in Windows Disk Management. Then, try to change the drive letter and path to make it show up.
Step 1. Right-click on This PC and select Manage. Under the Storage section, click Disk Management.
Or, use an alternative way to open Disk Management in Windows 10/8.1/8/7: Press Windows + R keys, type diskmgmt.msc in the Run box, and hit Enter.
Step 2. Right-click on the SSD partition and select "Change Drive Letter and Paths…".
Step 3. Among the Add, Change, and Remove options, click the "Change" button, and then select a drive letter from the list. Click "OK" to assign a new drive letter to the problematic hard drive.

How to Repair Corrupted External Hard Drive
In this part, we'll show you two methods to format a corrupted external hard drive and get it back to normal condition again. Before you proceed, it's necessary to know the kind of hard drive problems that you can use the disk formatting method to resolve.
Theoretically speaking, disk formatting should be done with caution because it erases data and removes installed programs. It's extremely useful, though. Disk formatting is the configuring process of data storage media for initial, so it can solve most common hard drive issues like "Disk is not formatted, do you want to format it now?", or hard drive is not showing up and displaying itself as RAW. Moreover, it can scan and repair bad sectors, and sometimes remove sophisticated viruses.
Sometimes data storage devices, HDDs, memory cards, or USB sticks are not recognized by the operating system, making it impossible to access professional or personal data. EaseUS provides a 100% working solution - a manual disk repair service. You can repair your external hard drives with the help of experts.

In that situation, you can download this piece of software to perform the formatting.

How to Repair Corrupted External Hard Drive Without Formatting
How to repair a corrupted external hard drive without formatting it? If you don't want to format it, or if the drive becomes unallocated, it won't work with the formatting method. Don't panic, though, as you can try the two methods outlined below.

How to Maintain a Healthy Hard Drive
All computers have a hard drive installed on them, which is used to store files for the operating system, software programs, and a user's data. A computer cannot work without a hard drive whirling. To correctly work with a hard drive, or an external one, you should have some necessary know-how skills for keeping a storage device healthy, and in turn, prolonging its life.
Therefore, we think you should adopt the following three habits in your life.
1. Everyday Data Backup
You can back up a whole hard drive data, a certain partition, user archives, or even an operating system. This is the most guaranteed way of attempting all chances of hard drive recovery without worrying about data loss (e.g., some fixes on this page are meant to erase data, making it unrecoverable). There are native backup tools for Windows, namely Backup and Restore for Windows 7, 8.1, and 10, and File History for Windows 8. But, modern users tend to prefer third-party free backup software. They like more intuitive, user-friendly, versatile, and, more feature-packed backup plans to replace the dull and flat Windows utility. EaseUS Todo Backup Free perfectly meets the everyday backup expectations for these users, including backing up a hard drive, partition, files, folders, etc.
2. Periodic Disk Cleanup and System Optimization
Remove junk files, useless and extremely large files, and system/browser cache files that occupy precious disk space to avoid the risk of the computer becoming slow. Use simple disk cleanup to boost hard drive performance.
In addition, the longer you use the machine in a settled location, the more dust and debris in the air will accumulate and cause the hard drive to overheat and malfunction. You may use a small piece of cotton rag and a dip of alcohol to clean it by yourself, and a cotton bud is also a good choice for the inside areas.
3. Take Advantage of Power Save and Sleep Modes
Though there are major brands that ensure a longer lifespan, you should admit the fact that the less time your drive is running, the longer it will last.
Therefore, turn the hard drive off when you’re not using it. Similarly, when your computer is idle, try to utilize the Power Save and Sleep Modes to keep it from performing certain general maintenance tasks such as defragmentation, checking Windows updates, third-party activities, and so on.
