Before giving away your old computer or hard drive, you might have deleted all your files even folders and formatted your hard drive. Is your data really gone? NO. Formatting hard disk does not really delete data; it just means Windows marks that space as rewritable, so it is possible to find all the data back by professional data recovery software until the space rewritten.
To permanently wipe data, you can physically destroy hard drive, or use software to achieve. If you are good at command line, you can use Windows build-in program "Cipher Tool" (Cipher.exe) to wipe hard drive. But for those who are not, you could use Partition Assistant Standard Edition (one free and perfect 3rd-party partition software). It is portable and easy to use, while ensuring deleted data unrecoverable. By this software, every sector of the hard drive will be overwritten with binary 1's and 0's. You can even overwrite your hard drive multiple times for added protection.
