Do a low-level format of the hard-drive. This will remove the operating system as well so it will no longer boot.

How to Completely Erase a Hard Disk Drive


Erasing a hard drive is a step that most computer users overlook. Just simply going through your data and using the delete key in Windows does not entirely delete the data. This just simply removes the shortcuts making it not visible to the user. If a person wanted, they can easily use software to obtain the data off the hard drive.

Fun Fact
A study was done and were 158 used disk drives were collected and the data retrieved. The two students found 5,000 credit card numbers, medical reports, detailed personal and corporate financial information, and several gigabytes worth of personal e-mail and pornography on those drives.

Disk Wiping Methods

There are two common methods for erasing data. These are formatting and wiping. Formatting a hard drive will not erase the data on the disk but will delete the address tables making it more difficult for average users to see the data, however, a computer specialist who is skilled can obtain some or all of the data using tools. Disk wiping is a more effective method and basically write over the data with 1's or 0's. The more times the disk is overwritten the more secure it is.

Disk Wiping Software
There are numerous free software utilities out there that will wipe your hard drive. I will recommend two programs and briefly go over them.

Eraser - Click here for download

Eraser is a advanced security tool for Windows that will completely remove data from your hard drive. It has a simple to use interface and uses multiple wiping methods such as Peter Gutmann's paper Secure Deletion of Data from Magnetic and Solid-State Memory.

You can use this program to delete files, folders, recycle bin contents and even free space on a drive. Click here for a quick start guide which will give you the basics.

-You can even use Eraser to wipe your flash drive.

Darik's Boot and Nuke - Click here for download

Darik's Boot and Nuke is basically software you boot your computer into. You can load the software into a floppy disk, CD, or USB stick if supported by your computer. Once you boot into the program, you select the wiping options and it will do the work. This is an effective program and I have used it before.

In order to boot your computer to the software you will first need to load the software on the media(usb/cd/floppy) described above then insert the media into your computer. Turn off your computer and as it is booting up you want to go into your computer BIOS. Usually, it will tell you what to press to get into BIOS during the boot up process. Once inside the BIOS you will need to change your boot order so it boots to the media device first. Once done, exit the BIOS saving your changes and the computer will boot into the media and start the data wipe software.

Tips

-If you are installing a new operating system I recommend you first wipe the hard drive using the methods described above, then formatting the drive for the new operating system. If you are giving away the hard drive or computer, I would recommend you wipe the hard drive before doing so.

How to completely erase everything without a secondary key


Wipe it really clean? Like erase Windows and everything?

Do you have the original disks that came with the computer? If you boot from a Windows installation disk, then you can reformat (wipe) the disk before you install. That's a nice clean install. If you want to go a step further, you could repartition the drive with fdisk, then format it.

If you're looking to keep windows, but erase all the programs and files, that's more tedious. Open Control Panel, go to Programs & Features. You'll see a list of installed programs. You can double-click on a program to uninstall it.

To get rid of files, I would suggest creating a new User account for yourself, give yourself Administrator permissions, and then delete your friends account. Then you can look in the Users folder, and if you see your friend's account on a folder, delete it.

How to wipe iPhone cleanly


"Erase all content" means all of YOUR content, including all applications you have downloaded and all the data for those applications and all the data for Apple applications (i.e. Mail, Photos, Calendar, Safari, etc.) will not be completely removed from the device, they still remain on your iPhone and can be easily recovered by some iPhone data recovery.

I highly recommend you to try Safewiper iPhone data eraser app to complete your iPhone data, it will be the best choice when you need to sell your old iPhone or iPad.

Scratched Finish on Screen While Cleaning


Here are some solutions to consider. Try in an inconspicuous place first.
1) Use a clean WHITE pencil eraser. Yes WHITE pencil eraser. Some people use a pink eraser and then a white eraser over that for faster removal. Wipe residue off with a damp cloth.
2) Use White Petroleum Vaseline Jelly over the stratches. This may have to stay on an hour before wiping off.
3)You may also get commercial LCD scratch removers on the 'net.

An LCD screen should only be cleaned by using a damp(not wet) with water microfine cloth. Never use household cleaners of any kind.
