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.

You need to reinstall by booting from a install disk and make sure it is booting from the cd/dvd once this is done the install should complete with a working copy of windows on this computer.

Boot sector virus - can't do low level format or repair?


For this fix, it will require a full data wipe.

Be sure to back up all of your data that is important to you. Your going to need a few things to download first.
1.) USB thumb drive or blank DVD (Make sure your PC is bootable via USB or CD in BIOS.
Download this program and burn it to a disk. Do NOT unzip.
http://downloads.sourceforge.net/project/dban/dban/dban-2.2.6/dban-2.2.6_i586.iso?r=http%3A%2F%2Fwww.dban.org%2Fdownload&ts=1298878936&use_mirror=cdnetworks-us-2
Boot your computer with that disk, and follow the onscreen instructions to completely wipe your hard disk. Be sure you have the ability to re-install Windows.

How do I get around the error message: Non-system disk or disk error, replace and strike any key when ready". No disk in the CD drive.


What is happening is that your laptop's BIOS is not "seeing" your hard drive, it is set to boot to a USB device and one is plugged in, or it is not seeing the necessary boot files (on any device) in order to boot up. You have one of a couple problems - either your hard drive is failing or you inadvertantly deleted one or more important files needed to boot up. Happens all the time.

In order to fix your laptop, you first need to determine if your hard drive is even being recognized. You need to enter the BIOS setup and see if the hard drive listed and what the boot order is. If you don't know how to enter the BIOS, then you would probably be better served to take it to a qualified technician who can get you going.

If your BIOS does not see your hard drive, then you drive has likely failed and will need to be replaced. If it is listed in BIOS, then you will need to repair the boot files. Depending on which version of Windows you are using, it is pretty straighforward. You simply insert your Windows boot CD-ROM and boot from that disk. Ignore the first "Windows Repair" option and select "Install Windows" (if it is Windows 7 then you will be asked for startup repair, select this.) Windows will then "see" your windows installation on the hard drive and you will be asked if you want to repair it - and yes, you do. After repair, your windows should boot. You may have to reinstall some applications as the registry may or may not be scrubbed. All your data files should be intact.



Remember, always back up your computer!

Had to wipe my acer aspire 5315-2077, only thing I did not erease was my bios setting . I need a startup disk or boot disk or can I use my old xp cd or me. cd.


Yes but not ME cd. You can use your old XP cd as a boot disk, ensure that you have set the boot order to CD drive for the first boot, and upon restarting make sure the XP cd is in the CD drive.

Trying to boot from windows CD and not working


If its the full windows xp cd by booting it from the cd drive it will erase everything and ask if you want to upgrade or advanced install I think. Your correct in choosing the atapi cd-rom as 1st boot device. The cd should be in the drive on startup. IDE is the type of hard disk drive. I'm guessing the FDD stands for floppy disk drive which you might not have that many but you have that many bay windows available.

Put disk in, shut down computer, Start computer and it should give you the xp disk contents. Be aware of data loss though.

Erase a hard drive


IF you have the XP installation CD you can easily do that, Just set your BIOS to boot from the CDrom then put the XP CD on your CD drive then restart the computer , so your computer will automatically boot from the XP installation CD then on that process you will have an option to format the entire hard drive that you have using the XP CD installation, then just let the installation finish...

Computer boot up


just worth a try if your using XP. :) using XP recovery console:

To run the Recovery Console from the Windows XP startup disks or the Windows XP CD-ROM, follow these steps:
1.    Insert the Windows XP startup disk into the floppy disk drive, or insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer.

Click to select any options that are required to start the computer from the CD-ROM drive if you are prompted.
2.    When the "Welcome to Setup" screen appears, press R to start the Recovery Console.
3.    If you have a dual-boot or multiple-boot computer, select the installation that you must access from the Recovery Console.
4.    When you are prompted, type the Administrator password. If the administrator password is blank, just press ENTER.
5.    At the command prompt, type the command:

chkdsk  /r

6.    When finished checking, exit the Recovery Console and restart the computer, type exit at the command prompt, and then press ENTER.

Also verify that your HD has been set to master in Primary IDE and the others (if you have like CDROMS) in as slave.
