How To Wipe A Linux Laptop
If you’ve got a Linux-based machine, wiping any of the hard drives – internal or external – is a slightly fiddly process that involves using the command line.
Open up a command line terminal and enter ‘sudo fdisk -l‘. This will list all the storage drives currently connected to your machine. Find the drive you want to wipe, and note the drive’s device path.
Next, run this command – ‘sudo dd if=/dev/zero of=/dev/sdb bs=1M‘ – via the terminal, making sure to substitute ‘/dev/sdb/‘ with the target drive’s correct device path. This method is known as ‘zeroing’, and wipes the drive by overwriting every byte of information with zeroes.
There is some debate as to whether or not this is more secure than overwriting the drive with random bits of information, but it’s usually quicker and is perfectly sufficient for protecting your data from the average buyer.

Overview On Wiping A Hard Drive
It’s common to most users to sell or give away computer or hard drive when they want to dispose of old device or upgrade to new ones. You may have already formatted the hard drive or deleted files on it in order to erase sensitive personal data and avoid becoming the victim of identity theft.
However, the fact is that wiping out a hard drive is not as easy as deleting data or formatting hard disk. Simply deleting files by Shift + Delete or emptying the Recycle Bin does not permanently clear data, as deleted files can easily be recovered by recovery software. Formatting a hard drive does not completely erase data either. Though operating system cannot see deleted or formatted data and the drive looks empty, average users are able to get back lost data easily with the help of hard drive recovery software.
If you view tech forums or comminutes online, you can see lots of users looking for an easy way to clean storage devices, and here is one of them:
“What is the best way to clean the hard drive of my laptop? I’m going to selling it to someone but want to ensure all personal files are securely erased. What I want to do is cleaning hard drive completely and reinstalling Windows 7 . Everything on the hard disk has been backed up to my external hard drive, I’m hoping one of you here can tell me how to clearing PC step by step? I know how to install Windows from CD but have no idea how to safely wipe hard disk. Many thanks!”

What Is A Factory Reset
A factory reset factory reset means deleting anything that wasn’t on the device after it came out of production, so this will definitely make it impossible for you to practically access programs or files on your computer.
It’s important to know what a factory reset actually does, though. It puts all applications back into their original state and removes anything that wasn’t there when the computer left the factory. That means user data from the applications will also be deleted. However, that data will still live on the hard drive.
Factory resets are simple because they’re programs included on the computer when you first get your hands on it. It’s useful to reset errors with an operating system or helping restore the computer’s functionality or speed.
There are limitations, though. Factory resets leave data in the hard drive, so those pieces will live on until your hard drive is overwritten with new data. In short, the reset can give you a false sense of security. A complete erasure would actually look more like degaussing , or actually smashing up the hard drive to bits.
Context is still key. If you only ever really played games or finished school work on your computer, there’s probably little risk in using a factory reset as your primary form of data wiping.
