Are you getting rid of your computer? You may have erased your private data by deleting files and reinstalling Windows, but you’re not quite done yet. Remember, those items can still be restored from the Recycle Bin or recovered with the right utility. The last action you need to take before saying goodbye to your old friend is to wipe the drive clean.
No matter which version of Windows is installed on your PC, there are built-in features to reset the OS to factory conditions. However, most computers now come with solid-state drives (SSDs), which are faster than their mechanical counterparts but can be trickier to wipe. To be certain your data can’t fall into the wrong hands, a good third-party hard drive eraser is still your best bet if you want a stronger and more secure method of wiping your drive.

Wipe Your Drive in Windows 7
Windows 7 users won’t find the same reset tool built into newer versions of the OS, but you can still bring your hard drive back to factory settings under the right conditions. To make the process go smoother, you’ll need either a recovery partition or the Windows 7 installation disc.
Open Control Panel, choose Recovery, and then click the Advanced recovery methods link. (Note that if your PC doesn’t have a recovery partition, you may receive an error here, preventing you from moving forward.)

You’ll be presented with several different options on how you want to reinstall Windows 7. After making your choices, choose Skip when asked to back up your files, then click Restart to reset Windows. Depending on the option you chose, you can now reinstall and set up Windows 7, thereby wiping out the previous installation.

Wipe Your Drive with a Third-Party Disk Utility
Wiping your storage drive from within the operating system is a quick and convenient method, but a third-party utility can provide greater security and protection. For those of you erasing a mechanical hard drive, make sure you choose a utility that meets the DoD 5220.22-M standard. This means the utility will fully wipe your drive by overwriting your data three times with different characters.

Disk Wipe
Disk Wipe is a free, portable erasure utility that runs from a USB drive and wipes your Windows boot drive. Simply download and run the DiskWipe.exe file on your PC, or create a bootable environment on your USB flash drive and have Disk Wipe run from there. The utility’s simple interface displays your drives and partitions. Select the one you want to erase and click Wipe Disk.
The program asks how you want to format the drive—NTFS, FAT, or FAT32. You then choose the type of erasing pattern and the number of passes. Options include One Pass Zeros, One Pass Random, or US Department of Defense DoD. Generally, the more passes you choose, the longer the process takes but the more secure the erasure.

Active KillDisk Freeware
Active KillDisk Freeware is a more limited version of the $49.95 KillDisk Professional for Windows, but it’s still a capable and effective tool. You can easily create bootable disk wipe media on a DVD or USB drive, or set up an ISO file. You then use that media to boot up your Windows PC, where you can wipe the primary drive.
The program provides a graphical menu showing your various drives. Select the drive you want to erase and click the Erase Disk icon. KillDisk offers a range of erasure methods, including those from the DoD, US Army, British government, and NIST.

AOMEI Partition Assistant Standard
AOMEI Partition Assistant Standard is a free disk partitioning and management tool that lets you easily wipe your drive. The program helps you create a portable version that you can run from a USB drive as well as bootable media to burn to a CD/DVD, copy to a USB stick, or save as an ISO file.
From the main interface, select the drive or partition you want to erase and then click the Wipe Disk icon. The only drawback with the free version is that it limits you to just one erasure method, namely filling the sectors with zeros. To use more advanced methods, you’ll have to upgrade to the paid AOMEI Partition Assistant Pro.

Experience
I’ve been working for PCMag since early 2016 writing tutorials, how-to pieces, and other articles on consumer technology. Beyond PCMag, I’ve written news stories and tutorials for a variety of other websites and publications, including , ZDNet, TechRepublic, Macworld, PC World, Time, US News & World Report, and AARP Magazine. I spent seven years writing breaking news for as one of the site’s East Coast reporters. I’ve also written two books for Wiley & Sons—Windows 8: Five Minutes at a Time and Teach Yourself Visually LinkedIn.
I’ve used Windows, Office, and other Microsoft products for years so I’m well versed in that world. I also know the Mac quite well. I’m always working with iOS, iPadOS, watchOS, and Android on my various mobile devices. And these days, I write a lot about AI, so that’s become another key area for me.
My wife always jokes about all the tech products we have around the house, but I manage to put them to good use for my articles. I like Lenovo computers, so I own a couple of Lenovo desktops and several laptops. I have three MacBooks and a Mac mini. For my mobile life and work, I use an iPhone 16 Pro, iPad Pro, and iPad mini as well as an Apple Watch. But since I write about Android, I own several Android phones and tablets. Like any tech person, I have a cabinet full of cables, wires, and assorted mysterious gadgets. And when it’s time to take a break from writing, I have an old Xbox 360 and Nintendo Wii, both of which I use for exercise and fitness games.
