Why need to do a bootable disk wipe?

When you want to change a new desktop computer or laptop, it is necessary to wipe the internal hard drive before abandoning or selling it, but Windows does not allow you to wipe the internal hard drive. And you can make a bootable USB that can directly boot up your PC without entering the Windows system to wipe your hard drive. Especially, Windows 11 removed the Windows to Go function, there are some people who want to wipe a disk to make it a Windows 11 bootable USB.

And when it comes to erasing data on a hard drive, some people may try to delete and format the data on it. However, simple deleting is not secure enough to wipe a disk.

▶ Differences in formatting, deleting, and wiping:
· Format: During the formatting process, information is encoded for storage on a computer. It's usually used for initializing a new disk.
· Delete: This operation leaves an empty space that may be used to build more divisions.
· Wipe: Wipe data on a hard drive or partition completely and permanently; some wiping software involves overwriting random data on the disk to cover the original data to prevent data retrieval.

To avoid data recovering, you'd better choose a reliable data wiper that is capable of making a USB bootable and easing data completely and permanently.
