But if you want to format your hard drive completely, there is an easy way to do it, without using tools third parties.
Η Microsoft from 2007 to the failed one version of Vista which has been added, has added the parameter P to the DOS command of Format. The / P parameter allows you to more securely format a disk by completely erasing the data it contains. .
So from the Windows 7 and then you can use the Format command with the / P parameter.
But what does this parameter do?
The Format / P parameter in the Format command will allow you to specify the number of passwords to delete the data on your disk. Besides, extra passes will replace 0s in your drive sectors with random numbers.
But let's see how it works
1. Type them together Windows Key + R
2. In the box that opens, type cmd and press enter
3. In the command line window that appears, type the following command by changing the parameters.
Format g: / P: 8

So if you want to try the command, change the parameters that are in brackets:
Format (disk letter): / P: (desired number of passes)
