I just bought and installed CCleaner Professional Plus with the whole suite: PRO CCleaner, Recuva, Defraggler & Speccy, for up to 3 PCs CCleaner Pro
I read the Help on the web site, so I am aware of all the wiping options.
When in CCleaner I go to > Tools > Drive Wiper I can see my C hard drive. Unfortunately, hard drive is erroneously marked as SSD drive. If I chose "1 pass" wiping I can do the wipe. But if I choose "7 passes" or "35 passes" wipes my C drive becomes unselectable and I can not perform "7 passes" wipe.
How do I correct this problem and "force" CCleaner
