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?
