Things you need to do before you sell your hard drive or laptop computer

In this video, we are going to show you how to securely wipe you hard drives to ensure your personal information is securely deleted. alright! we will start by talking about what software is needed. there are many software available for this type of job. some are free and some are not, but lets talk about the FREE ones. for example Active Kill Disk the hard drive eraser. this software utility adheres to the united states department of defense standards for removing data. and its also free. another one is the software called Eraser from heidi computers, another free utility based on different standards. you can even define your own method for over writing data that allows you to securely erase specific files and folders. but then why would we need another utility to securely wipe hard drives and solid state driver when we can have it included by a freeware called c cleaner which is free for home use. I have this 500 gigabytes hard drive and a hard drive enclosure. we will try to do a secure wipe on this drive using C cleaner. first I'm gonna put the drive inside the enclosure and plug it to my computer. oh by the way, this mac run on windows.
