Recently, I was able to wipe the entire C drive clean before returning the PC to the company. I clicked on "Entire drive (All data will be erased) and Advanced Overwrite (3 passes). The wipe took quite a while; I was pleased to see that when it was competed, the entire drive was clean.
I just tried using Drive Wiper on another computer but when I try to access the above actions, nothing happens, C is not highlighted. Don't understand the concept of "Free Space Only." Don't know what free space is or why I would want to wipe clean space that's empty.
Your help on how to be able to do the total drive wipe, as I did before, will be very much appreciated. ec
