What's the best software for completely erasing a hard drive?

[JrFreak]

Looking for software to write zeros to HDDs. I have a few lying around that I don't use and might put them up on eBay while the prices are high. I want to make sure these go out without any data left on them.

Thanks!

One free is ErAce. It will over write hard drive 1-100 times. Last cycle is zero. You can find it from erace.it

dban is the most recommended one. Because it is free.
In fact, there are many choice. Like this one: http://giveumore.com/wipe-computer.html Easy to use and also enables to erase USB drive, SD card, memory card, and so on.
Try and choose the one you like.
