It is a good idea to completely erase all of the information on your PCs hard drive when you get rid of it, and on your cell phones, PDAs or other devices that store your information. It’s harder to do than it sounds though. Simply deleting the information in not enough, because it is really still there until something else is written over that spot on the disk.
There are special software programs that safely erase all the information stored on a disk by writing over the disk several times, but that can take a long time. To find some options, go to PCWorld.com, a leading PC magazine and help site. Use the link below to see the list of products under file management, and enter “”disk wipe”” in their search tool.
