It depends if the person intends to keep the computer or sell/donate it. I have always recommended BitEraser or East-Tec Eraser. BitEraser is great since it provides a Digitally Signed Certificate in the event you consult with companies or people who need proof the data was destroyed.
Of course, if there ultra serious privacy issues, I would wipe the entire drive and then physically destroy it as noted in the preceding post. Again, it depends upon the threat level, and in some cases the law, for example if you are a defense contractor replacing a computer with a new one. Nonetheless, I wish every here happy hunting for the best privacy option. Darren Chaker
OK, assuming that the data drive in question is a mechanical drive and not an SSD..... and is worth saving.
There is a old program, that I still have but seldom use, called "Low Level Formatter". (LLF)
It literally scrubs the surface of the 'Platters', writing different bit patterns over and over again, to every sector.
Also, a DOS format of the drive does something very similar, but just not quite as intense.
And it blocks out any sectors that "can't take the heat".
It's very similar to the software used by HD Manufacturers to Prov a new drive. Once the program completes its run, the drive is just like a brand new one.
I'm fairly certain that LLF is still available out there on the Internet. I found it!
