How to Format Drive or run Check Disk using Command Prompt.

How to Format Drive or run Check Disk using Command Prompt

Today I tried to connect my old Seagate external drive to my Windows 8.1 PC after a long time and found that I was just unable to access it. When I connected it, in the This PC folder, the green bar just kept loading, and when I tried to right-click on this drive letter, the circle just kept whirling round and round. The only way I felt I could start using the external drive again was to check it for disk errors and format it, if required.

External hard drive inaccessible

If you face such a situation, where you find that your USB or external hard drive has become inaccessible, then this tutorial will help you as it shows how you can check disk for errors and format it too, using CMD or the Command Prompt, and hopefully succeed in getting back access to it.

Run Check Disk using CMD

check disk cmd 400x360 How to Format Drive or run Check Disk using Command Prompt
Using the WinX Menu in Windows 8, open an elevated command prompt windows and type the following:
chkdsk /f E:
Here E is the letter of the USB or external drive – or any drive for that matter – where you would like to scan for errors and repair the errors if found. So make sure you replace it with the correct letter in your case, carefully, and hit Enter.
The Check Disk operation will start on the drive, and it will also repair any errors which may be found.

Once Check Disk completed successfully on my External Drive, I found that I was able to access it.

Format Drive using CMD

I then backed up the data and decided to format it. To format a drive using CMD, type the following command and hit Enter:
format E: /fs:ntfs
defrag cmd 400x268 How to Format Drive or run Check Disk using Command Prompt
Again, here E is the letter of the USB or external drive which you want to format. So make sure you replace it with the correct letter in your case, carefully. Once you are sure, hit Enter. You may be asked to enter the Disk Label too. Type it and hit Enter again.
Disk formatting will commence.
