How to Run CHKDSK on External Drive Windows 10
Running CHKDSK (Check Disk) on an external drive in Windows 10 is straightforward. You’ll use Command Prompt to check for and repair disk errors. Here’s how: Open Command Prompt as an administrator, type the CHKDSK command followed by the drive letter, and include the necessary parameters. This brief guide will walk you through the process step-by-step, ensuring your external drive remains healthy and error-free.
Step-by-Step Tutorial: How to Run CHKDSK on External Drive Windows 10
Let’s dive into the detailed steps to run CHKDSK on your external drive using Windows 10. This tool will scan the drive for errors and attempt to fix any it finds.
Step 1: Connect the external drive
Plug your external drive into an available USB port on your Windows 10 computer.
Ensure the drive is securely connected and powered on. It’s essential for the subsequent steps.
Step 2: Open Command Prompt as an administrator
Click the Start button, type "cmd" in the search bar, then right-click on "Command Prompt" and select "Run as administrator."
Running Command Prompt as an administrator is necessary for CHKDSK to have the required permissions to execute properly.
Step 3: Identify the drive letter
Open "This PC" (File Explorer) and note the drive letter assigned to your external drive (e.g., E:).
Knowing the correct drive letter is crucial for targeting the specific drive you want to check.
Step 4: Enter the CHKDSK command
In the Command Prompt window, type chkdsk E: /f /r
and press Enter. Replace "E:" with the correct drive letter.
The /f
parameter tells CHKDSK to fix any errors it finds, while /r
locates bad sectors and recovers readable information.
Step 5: Allow CHKDSK to run
Follow any prompts that appear, and wait for CHKDSK to complete the scan and repair.
Depending on the size of the drive and the extent of errors, this process might take some time.
After running CHKDSK, the tool will scan your external drive for errors and attempt to fix them. If any bad sectors or file system errors are found, CHKDSK will handle them, ensuring your drive functions smoothly.
