Hello,
I've just bought a Ccleaner proffesional and I would like to use a drive wiper. When I set the security to 1 pass everything works correct, but when I try doing it with 3 or more passes all of the drives become "invisible" and it is impossible to choose them to perform the operation (See attached picture).
What am I doing wrong? How can I use a drive whipper with security of f.e. 7 passes?
Cheers,
Igor
