Why Should I Complete Wipe A Laptop Hard Drive Or SSD?

Why should I erase all data on laptop Windows before selling? There are many scenarios that you want to wipe laptop data, for example, you want to throw, sell or recycle it. The laptop contains plenty of important personal information, say, family photos, business critical data, browser history, back account, emails, medical records, etc.

Whether or not securely wiping computer largely relies on what you plan to do with it. If you want to keep using the laptop, you just need to reset computer to a fresh version of Windows. However, if you want to sell or recycle the computer, you should take extra steps to make sure all sensitive data is inaccessible to next owner.

When wiping data, don't just delete files from Recycle Bin. Dragging files to Recycle Bin and then emptying Recycle Bin or reformatting hard drive does not permanently clear files. Although deleted and formatted files appear to be invisible, most data recovery software can get them back easily. When files get deleted or formatted, only file entries are erased, making files invisible to users. Yet disk space once taken up by lost files still keeps data, so data recovery software can find and restore them again. The hard drive wiping process is going to erase any recoverable data on the disk. The rest content will show you how to clean laptop hard drives and SSDs off any data, protecting you against any data thefts.

Backup Important Data Before You Start

The laptop for which you want to wipe data must contain important data you may need in the future, thus the first thing you should do is to back up important files to a secure place. When it comes to data backup, you can simply copy files to an external hard drive. Make sure the external hard drive has enough storage space. If the external hard drive is not large enough, then back up data to cloud drives like Google Drive, Dropbox, OneDrive, etc. Moreover, there are more backup options and methods available if you use third-party software DiskGenius Free Edition. With DiskGenius, you can easily:

  • Back up the entire hard drive or SSD into an image file.
  • Migrate Windows OS and personal files to a new hard drive or SSD.
  • Clone hard drive/SSD to a new one.
  • Back up a partition such as C drive into an image file.

In addition to data backup, the other thing you should pay attention is to unlink any software subscription form the laptop. Some paid software is registered on a computer by binding the computer hardware so that it can detect whether it is the correct user. So you may need to contact the software provider to deactivate the software so that you can continue use the software on your new computer.
