I've been searching for a bit and can't seem to find an answer. I prefer using DBAN because for the most part it's a sturdy tool, but I've wanted to find a tool forever that does as through of a job as it does while in Windows so I can do stuff like wipe external hard drives, flash drives, etc and still use the computer for other stuff. So I'm wondering when doing a full wipe on a drive does CCleaner fill every sector from sector 0 to the end of the drive then make a new partition or does it delete all the files and make a file big enough to fill the free space in the partition? Also was wondering if it uses random data or zeros?
Please do not tell me I should never wipe a flash drive because it will shorten it's life, I'm sure that's true to some extent but I have two flash drives that are near ten years old and both have been wiped probably over 50 times since they were bought with zero fills and still function fine.
