Does formatting a USB drive wipe it completely?

The USB drive is an easy-to-carry device for users to store data or transfer files from one computer to another. But when you plan to donate, discard or sell it, or eliminate unknown but stubborn virus/malware on the USB drive for reuse, you might want to delete everything of a USB stick.

For this purpose, users are more likely to format the USB drive using Command Line, Disk Management or File Explorer. But does formatting a USB drive erase it completely? The answer is “No”. Formatting a hard drive does not erase the data on the disk, only the address tables, making it much more difficult to recover the files. However, for some computer specialists, it would be easy to recover most or even all data that was on the disk before the formatting.

More secure way to delete everything on USB-disk wiping

Since formatting is not good enough to remove all data from the USB device completely, we need a more secure way to do that. It is called (USB) disk wiping.

Disk wiping is a secure method of ensuring that all data, including individually licensed software on the target disk, is irrecoverably deleted. The disk wiping process will overwrite your entire hard drive (Master Boot Record, partition table and every hard drive sector) with zero or random data several times. The more times the disk is overwritten and formatted, the more secure the disk wipe is.

Tip: to choose another three disk wiping methods, please upgrade to Professional edition.
Fill sectors with random data: This method will write random data to all sector on the USB drive, making it harder for recovery software to find any meaningful data.
DoD 5220,22-M: This is a software-based data sanitization method, and it can prevent all software-based file recovery methods from recovering data from the drive. This is very much safer but takes a longer time.
Gutmann: It is also a software based data sanitization to overwrite existing information on a hard drive. It will prevent all software based file recovery methods, and most hardware-based recovery method from retrieving information on the wiped drive. More passes (35 passes) make the erase more secure, but take more time.

Step 3. Click “Apply” to start executing the pending operation.
