DIGITAL DATA ON DRIVE DELETION

DIGITAL DATA ON DRIVE DELETION.

OK, sometimes you just have to get rid of that pesky
old data on your hard drives quickly and completely.
Well, there are some programs out there that can
accomplish this. Just be very sure, and I mean VERY
SURE, that you want the data gone for good.
Here are some of my favorite links.

Eraser is easy to use, and downloadable from :
http://www.heidi.ie/eraser/

Autoclave is
a great, and easy to use program to use. Tips of
the hats to Josh Larios.

NEED TO SERIOUSLY DELETE DATA ON YOUR HARD DRIVES?

clave03.img -download the image file

"DO NOT DOWNLOAD THIS FILE ONTO THE FLOPPY DISK. Download it to your hard drive. It is too large to fit on the floppy; we'll be using a special program to install it onto the floppy in step 3.

The downloaded file clave03.img should be 1,474,560 bytes long. You can see how large the file is using the "dir" command, or by getting the properties of the file from the windows explorer. If it is any other size (1,477,970 is the most common wrong size), do not go to step 2; you have a corrupt disk image. Try downloading a zip file containing the disk image from http://staff.washington.edu/jdlarios/autoclave/clave03.zip and extracting the file clave03.img from the zip file."

Download rawrite2.exe from http://www.tux.org/pub/dos/rawrite/
or RawWriteWin from http://uranus.it.swin.edu.au/~jn/linux/rawwrite.htm."

http://dban.sourceforge.net/Darik's Boot and NukeDarik's Boot and Nuke ("DBAN") is a self-contained boot floppy that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.
