How to Erase a Hard Drive

A computer’s hard drive, depending on its capacity, is capable of, and most times responsible for, storing a massive amount of information that is both operational and personal. Over the course of time, you may find that your computer’s performance decreases due to the amount of data you have stored within the hard drive, resulting in a need to free up some space. If you’re selling your computer, or just want to wipe out the hard drive to install a new operating system, performing a proper erase of your hard drive isn’t as difficult as some might think. If you’re preparing your computer for disposal, however, erasing your hard drive completely is imperative in order to protect your personal information. 

When you’re starting the process of erasing your hard drive, the first thing you need to do is back up the important information and files you don’t wish to part with. Transferring these files to an external device will allow you to access them if you decide later on that erasing them was a bad idea. Once you have your files transferred to either a different drive or an external device, you’re ready to erase the hard drive’s information. 

Starting to Erase

When you want to erase a hard drive, you’ll need the installation CD for your operating system to put in the computer’s disk drive before you start.

• Once the disk is in the drive, you’ll be able to restart the computer.
• As your computer reboots, you’ll be given instructions as to what button to push to bypass the typical boot screen and access the computer’s boot menu (usually F12 or another “F” key).
• From the computer’s boot screen, press “R” to enter the Recovery Console for the computer.
• When this screen appears, you’ll see a format screen with a command heading and a blinking cursor.
• Enter the heading “format c:/ fs:ntfs” and you will be warned that pressing enter will erase the hard disk information.
• Press enter and allow the formatting process to complete.
• At this point, your hard drive will be erased of its ability to retrieve any data that may be on it. 

Erasing Before Selling or Disposal

If you just want to erase your hard drive to start over and put a new operating system or software on for yourself, then this process for how to erase your hard drive is pretty much all you need.

However, if you’re disposing of or selling your computer, you should look into a wiping or erasing agent program to make sure that the hard drive is truly erased before you let anyone else take it away. This will ensure that the next user, or anyone who comes into possession of your computer, is unable to access any information by recovering the hard drive.
