The necessity to wipe a USB drive

Want to discard, resell, or give away a USB drive? Then you must be extra careful with the data issue. According to a study from Comparitech, a significant percentage of people do not properly erase all the data before throwing away their USB drives, and a small percentage do not even make an attempt.

As a result, the leftover files including business documents, job applications, private photos, ID scans, receipts, etc. might be transparent to deliberate snoopers. It’s not hard to image how catastrophic this would be. Even worse, the data that has been manually deleted can be retrieved with recovery tools easily.

On the other hand, when you reuse an USB drive or purchase a second-hand device, you may also be concerned about legacy data, viruses, or even surveillance software. If you really want to avoid such worries, it’s a must-do to completelywipe your USB flash drive or hard drive.

Can a flash drive be erased or reused?

Yes, a flash drive can be erased and reused multiple times.

To erase a flash drive, you can simply format it using your computer's built-in formatting tools or third-party software. Formatting removes all data from the drive and prepares it for reuse. Keep in mind that formatting doesn't securely erase the data; it can still potentially be recovered using specialized software.

Once a flash drive is erased, it can be reused for storing new data. Flash drives are designed to be rewritable, allowing users to delete old files and write new ones as needed. As long as the flash drive remains functional, it can be erased and reused countless times.

How to wipe a USB drive completely (3 methods)

Method 2. Erase a USB drive with Format

Before starting, it should be clear that formatting or deleting is not the same as wiping. When you format a USB drive, the data is still here, just can’t be accessed by the operating system. There are chances to recover it until the specific sectors are actually overwritten. But if you don't have any sensitive data on the USB Drive, this method might be sufficient.

1. Connect the USB drive to your computer, make sure it can be detected in File Explorer. Thenright-click the drive to choose Format.

DiskPart gives you options to format or clean a drive, here I’ll introduce clean command since it’s a safer way to erase data. But please note, if you use “clean” command in the last line, it won’t wipe the USB drive thoroughly, and the data is still recoverable.

To remove sensitive information securely, please use “clean all” instead, though it will take longer time.

How to clean a flash drive or hard drive with command:

1. Search for “CMD” to find Command Prompt, and choose Run as administrator.

3. Enter following commands and press Enter after finishing each line.

Diskpart
List disk
Select disk x
Clean all

*x refers to the disk you want to select

After completion, all the partitions on the USB drive will be wiped out. If you want to keep it for reuse, you can initialize the disk then.
