How To Completely Wipe A Hard Drive

Got a new PC? Bet you’re excited to explore it and toss the old one out.

Not so fast! If you’ve got private information on your disk drive, you have to secure it. Otherwise, you risk exposing yourself to identity thieves.

Sure, you can delete files. However, deleting only hides your files, it does not completely remove data. Thieves can use data recovery programs to access your deleted files.

Next, you can shred files, removing them from the disk drive completely. However, this will only let you work on an individual file at a time.

Lastly, you can wipe or scrub your HDD or hard disk drive clean, completely removing all files and private information.

So if you are going to let go of an HDD containing your files, the best thing to do is to “wipe” it clean. Allow us to tell you how to do it.


Different Ways to Scrub a Disk Drive
  1. Reformatting a drive is thought to be a solution to cleaning out personal data. However, formatting does not always clear out all the data there is on a hard drive.
  2. You can also elect to encrypt your entire hard drive instead of deleting the data completely and do as you please with the encryption key. Although this is usually enough, the data is not removed at all.
  3. You can also destroy data using software which securely erases or wipes clean a hard drive.
Before You Begin Wiping Data from Hard Drive

Before you wipe your hard disk drive of all the data it contains, back it up first.

You can never tell if you will need your files from your old disk drive. So create a back up in an external storage device, CD or cloud storage. Once you wipe the data, you won’t be able to recover it.
And that’s basically the idea we’re getting at here.

Also, remember that in some cases, there are multiple drives on a single hard drive. Make sure to check the drive volumes in the Disk Management Tool in Windows operated PCs. Or, you can use Windows Explorer or File Explorer to view all disks present on your computer.

If you don’t have backup software, following are a few free backup software programs to use.
