Mainly divided into the following situations.

  • The first is that when you need to sell or throw away a computer, be sure to wipe your hard drive to prevent data from being stolen by others.
  • The second situation is when your hard drive has been damaged and you need to replace the hard drive. While damaged hard drives may be unusable, there is still the possibility that someone can recover data from them and use them for identity theft, etc.
  • The third case is that you need to upgrade the hard drive to a solid-state drive. After upgrading from a hard drive (HDD) to a solid-state drive (SDD) and migrating data to the new drive, wipe your old drive if you plan to give it away or dispose of it.

Why Need to Wipe Secondary Hard Drive?

Some users will choose to delete the data on the hard disk or format to clean up the data. But there is still a big risk in this way. If you want to completely wipe data to prevent your own data from being leaked, wiping the disk is the best way.

In a hard disk, files are stored on the surface of a magnetic and spinning platter. When a disk reads or writes data, your hard drive turns the magnetic field on the platter's surface to a 1 or 0. All data on the hard drive is ultimately saved as basic binary data. Erasing data removes binary data by overwriting zeros and ones with new data. Once a file's binary data has been changed and overwritten with new data, it cannot be retrieved.

Some professional disk-wiping software can fill drives sector by sector with zero or random data, ensuring that no data can be retrieved from the wiped disk.
