how to delete data from pen drive permanently?

My flash drive contains a lot of sensitive data. Now, I need to give my flash drive to one of my friends. I have formatted my USB Flash Drive using the format option in Windows. But I read somewhere that data recovery tools or professional data recovery specialists can still recover the information that was stored (of course with enough time and using the appropriate tools). I had stored personal data on the drive like passwords, financial records, my personal diaries and some classified documents from work, which I would rather not share with anyone. Is there any way to wipe my data beyond recovery? Is there any technique or any utility available?

You heard it right that data can be recovered from flash drives, even if you permanently delete them or format the drive. This is because Windows doesn’t allow to permanently deleting data. It goes on overwriting the data with time. Formatting simply replaces the file system. So, there’s every possibility of data being recovered using some low level scanning programs.
