Is formatting enough?

“I have purchased a new 64GB SanDisk SD card, so I intend to give my old 32GB Samsung flash drive to a friend. I want to make all things gone completely before giving. Is there anyone can tell me whether I can remove all data from it irrecoverably simply by formatting?”

The answer is negative

Formatting a flash drive only wipes its partition table and set a new file system. The data saved on it doesn’t disappear actually and just becomes invisible to the operating system. If you use certain professional data recovery software, the deleted data can be recovered easily. Thus, you are recommended to securely erase flash drive, which can wipe data from flash drive totally and irrecoverably. Then, how to perform complete data erase for a flash drive?

Great flash drive eraser tool for Windows

To get rid of data on a flash drive completely, a powerful flash drive eraser tool – AOMEI Partition Assistant Professional will be my preference. It is compatible with Windows 10/8.1/8/7, XP and Vista and rather easy to handle due to its concise and friendly graphic user interface.

The function Wipe Hard Drive of it allows you to totally wipe data from USB flash drive, SD card or hard disk drive (HDD). This function offers you four options listed below and you can choose one according to your own situation.

✔ Fill sectors with Zero: This way will write zero to all sectors on the flash drive.
✔ Fill sectors with random data: This method writes random data to all sectors, which is more secure than the first option.
✔ DoD 5220.22-M: A software-based data sanitization method, can prevent all software-based file recovery methods form recovering data. It is very much safer but takes a longer time.
✔ Gutmann: A software-based data sanitization way to overwrite existing information, preventing all software based file recovery methods from retrieving data and most hardware-based recovery methods form recovering information on the wiped flash drive. 35 passes make the erase more secure but take more time.
