Hi all. 
I have just one quick question; any recommendation for any full HDD erase software?
I did messed up stuff with partitioning HDDs, and now I can't undo that.
For some reason system of Win10 kept 320 GB (!) partition for his own stuff, and I can't do anything with it. And my PC behaves strange since that.
So ... is there any software which will erase HDD data completely? How safe is to use that? Tnx.
