Admit it! You all have been through a corrupted or damaged external hard drive at some point. No doubt external hard drives are a pretty useful tool for people who often find it challenging to organize their data. But facing data corruption or errors with the hard drive can lead to great disappointment.
Nevertheless, every problem comes with a solution, and a corrupted hard drive is no exception. You can use Windows build-in Command Prompt to repair a hard disk in different types of scenarios. For example, suppose you are a Windows 7 user and are not inclined towards downloading extra third-party software to get the hard drive repaired, then using the command prompt will the best option to go for.
So, if that’s the case with you too, continue reading further to discover how to repair an external hard drive using CMD in a Windows system.
If you’ve never used or heard of Command Prompt before, you’re not alone. Many people are not familiar with this pretty amazing tool even after using a Windows OS for several years. Basically, Command Prompt or CMD is a command-line interface that’s used to execute shell commands. All the command prompt commands are pre-defined and you’ll have to use them in the same way to perform the desired task.
It has been a crucial part of Windows OS since the beginning and can help you tackle many Windows errors by executing different commands. Even if your external hard drive has gone corrupt, you can use CMD to fix it. You may be even curious about what are the hard drive problems that can be solved by Command prompt. Here I list a few.
To repair any corrupt hard drive, you’ll have to use CHKDSK, also known as CheckDisk, an official Windows utility that’s designed to check the integrity of a hard drive and repair it in case of damage. CHKDSK is executed within CMD and can be used to repair both internal and external hard drives, irrespective of their storage space.
So, let’s quickly check out how to use CHKDSK in Command Prompt to repair a damaged external hard drive in Windows OS. For this tutorial, we’re using Windows 7, but you can follow the same approach on any Windows version to execute the CHKDSK utility.
First of all, let’s see how to use CHKDSK to repair a hard drive with logical errors.
Step 1 - Launch the “Start” menu and search for “CMD”. Right-click the first search result and tap “Open as Administrator” to run CMD as the Admin.
Step 2 - Now, execute the following command to check your external hard drive to find any logical errors.
chkdsk f: (Make sure to replace “f” with the letter that’s representing the external hard drive on your PC).
Step 3 - The previous command will only scan the hard drive for potential errors, but it won’t fix them. So, if you want to fix the errors, you’ll have to execute the following command.
chkdsk f: /f (“/f” is a CHKDSK parameter that’ll look for logical errors on the hard drive and try to fix them as well).
If the above command doesn’t repair your hard drive, there’s a huge probability that it contains bad sectors, which also means that you might have already lost valuable data from the hard drive as well. Fortunately, you can also use the CHKDSK utility to look for bad sectors and recover deleted files.
Here’s how to repair bad sectors on a hard drive using CMD.
Step 1 - Launch CMD as administrator by following the same steps as earlier. Then, execute the following command.
chkdsk f: /f/r/x (“/r” will look for bad sectors and recover any readable information. “/x” will dismount the hard drive before scanning so that the process doesn’t get interrupted by any external factor).
Step 2 - Wait for the above command to execute successfully. Now, type the drive letter of your external hard drive and press enter. This will change the current drive to your external hard drive.
Step 3 - Finally, type “attrib -h -r -s /s /d *.*” and press enter.
This command will automatically try to recover the lost data. As soon as the process completes, a new folder will be created inside the hard drive, that’ll contain all the recovered files.
While using a command prompt to recover data is a cool way to get back deleted files, it doesn’t work all the time. In fact, the recovery rate for Command Prompt is so low that you might never be able to retrieve all the files from a damaged external hard drive.
