Drive Wiper

I just noticed that with on my Laptop with Win 10 using CC v 5.46 the drive wiper is acting strange. I have several drives which include C (a ssd) E and F which are partitions on a normal hard drive. I have not run a wipe on the free space for ages so decided to run one on E drive. CC denied access to that drive. When testing on the others, it gave a warning for the ssd of C drive but then started the wipe, F started without problems. E drive however will not start even after testing other configurations in settings. It always pops up saying access denied. I upgraded to v 5.47 and still the same problem. So the obvious question is, what would cause such a glitch. Is it something I am doing or a bug in CC? Only thing I can think of at this point is to uninstall CC then do a fresh install and see what happens.
