Talking about portable storage devices, USB flash drives must task a place.

How to get rid of this situation?

After transferring files from the old USB drive to the new one, you may wipe the old USB stick for reuse, selling or throwing it away! How to wipe a USB flash drive completely and safely? Just keep reading to obtain the best 3 USB wipe tools.

# 1. Windows “format” feature

To help you wipe data on an internal or external device, Microsoft offers a “format” feature. There are two modes you can choose from: quick format and full format.

A quick format will only delete the journaling part of the file system. It does not really rebuild the file system, nor does it scan for bad sectors. In comparison, a full format will completely wipe your hard drive and check the drive for bad sectors and fix them.

To ensure there is no recoverable data left that a program could sniff out, a full format is recommended. Follow the steps below to perform a full format:

  1. Connect your USB drive to a USB port on your computer and make sure it is detected.
  2. Press Win + Ekeys to open File Explorer. In File Explorer, right-click on the USB stick and choose Format.
  3. In the pop-up window, choose a file system for your USB drive or keep the original one. Be sure to UNCHECK the box before Quick Format.Then click Start.
  4. When receiving a warning of data loss, click OK to start wiping the USB drive.

# 2. Windows Diskpart utility

Diskpart is a command-line tool that can be used to manage drives, partitions, volumes, and virtual disks on your computer. To erase a USB flash drive, you can run the “clean” Diskpart command with the following steps:

  1. Type “cmd” in the search box and select the “Run as administrator” option to open an elevated Command Prompt.
  2. In the Command Prompt window, type the commands listed below. You should press Enter after each command to execute it.
  • diskpart (launch the Diskpart utility)
  • list disk (list all the disks available on your computer)
  • select disk 1 (change “1” with the disk number of your USB drive)
  • clean (delete all data on the selected disk)

  1. Close Command Prompt.

Tip: Your USB drive will become not initialized and unallocated after running the “clean” Diskpart command. If you want to reuse the drive, you can initialize the USB disk and create a new simple volume on it using Disk Management.
