What does wiping a flash drive do?
When it comes to deleting files from flash drive, most users will use Windows inbuilt format options to format the flash drive. However, does formatting a USB erase all data permanently?
The answer is “NO”. Formatting or deleting flash drive partition only makes data invisible to the operating systems; actually they are still there and can be recovered with professional tools.

How to wipe a flash drive clean in Windows 10/8/7?
To completely wipe flash drive, you need the help of a professional drive eraser like AOMEI Partition Assistant Professional. It enables you to permanently erase everything stored on hard drive and replace them with garbage data in Windows 10/8/7/XP/Vista.
Besides, you will have four wiping methods to choose in the process. Depending upon the method you use, the overwrite data could be zeros, or various random patterns. Then we will look at how to wipe a flash drive clean step by step.
Precaution: This process completely wipes the entire disk you select, so ensure you back up any important files in advance.
Step 1. Install and run AOMEI Partition Assistant Professional (Try Demo Version), right click the flash drive you want to erase and choose “Wipe Hard drive”.
Step 2. In this window, you can choose a wiping method according to your needs and click “OK”.
● Fill sectors with Zero: this method means writing zeroes across the entire hard disk. It may also be called zero-fill erase or zero-fill.
● Fill sectors with random data: this method will overwrite random data to every sector on the hard drive to be wiped, making it more challenging for data recovery.
● DoD 5220.22-M: this method will overwrite existing information on a hard drive or other storage devices. It can prevent all software-based data and most hardware-based recovery methods from recovering information from the drive.
● Gutmann: this method also overwrites existing information on a hard drive, and prevent all software-based data and most hardware-based recovery methods from lifting data from the wiped drive. But it uses a random character for the first and last 4 passes, the uses a complicated pattern to overwrite from pass 5 to pass 31. Much safer than the other three methods.
Step 3. You will return to the main interface, click “Apply" to execute the operation.
If there is more than one partition on the flash drive, and you just want to wipe only one partition clean and keep others safe, you can right-click the target partition and select “Wipe Partition”.
You can use the same methods to wipe SD card, memory card, HDD and other hard drives. After wiping the hard drive, the disk space will become “Unallocated”, with which you can create a new partition for reuse.
