Software for complete HDD data delation.

Mar 30, 2018
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.
