You can use windows inbuilt diskpart software to do this from a command prompt
May not be the quickest (not sure) but its free and easy, just be sure to run "clean all" and not just "clean" as that will not securely overwrite the data

So I'm using diskpart to erase my HDD's. How long should it take to erase a 1TB WD black drive?

Hi Havoc.

I would suggest to use MHDD tool. It is free and very useful, not just in writing all zeroes but also it helps in diagnosing and fixing the bad sectors (well, more isolating to not to use those anymore).

Here's the link:

Please read the tutorial Pauly posted again. It states.

NOTE: See the green INFO box at the top of the tutorial for more information about this command. This command will wipe the HDD, and perform a secure erase. "Clean All" takes about an hour per 320 GB to finish running. It's best to only use this command if you wanted to help make sure that the data on the HDD cannot be recovered say when giving or selling the HDD to another person.
