Anuroopsundd's option is good, another option is using dban, which can be found here: http://www.dban.org/. This is a bootable linux CD that can "zero out" a hard drive by writing zeros to every bit.

The above tools are just fine for most cases.

>>> how to make sure if there is a way to make sure the hdd is 100%

There is no way to assure 100.0% data erasure because forensic methods can recover the data from the tracks.

So you need to know what is on your hard drive. Mostly, the low level formats take care of things. If you have sensitive information that would cause problems in the off-chance the information fell into the wrong hands, then it is best to get a new drive for the machine and destroy the old one.

Me? I just do low level formats. Clients?  They generally want the drives destroyed.

I second what tlabus suggested and also recommend DBAN. Burn the .iso image to a disc (make sure to create a disc image, and not just burn the file as data) and set BIOS to boot from disc drive. When it loads, type "autonuke" in the prompt and let it run. It will make 3 passes writing random data over the entire drive. Be careful and make sure that the drive you want to erase is the only drive in the computer, because DBAN will automatically erase every drive that it finds. So unplug your USB drives and extra hard drives!! Nothing will be recoverable, even using forensic methods. Take a look at this link and rest assured that the data will be gone forever:

as said - there is no 100% guarantee -  if they want to invest enough for recovery  -it can be done; but it will cost a lot of time and money
for average users, the suggested DBAN and alike are sufficient
many people offer a .45 through it -  but even then....
