BCWipe Total WipeOut versus Zero Write

[TheKid7]

BCWipe Total WipeOut shows many features including the following two features.

BCWipe Total WipeOut recognizes and can wipe Host Protected Area (HPA) on hard drives.

BCWipe Total WipeOut can identify the number of sectors hidden by the Device Configuration Overlay (DCO) function (present since ATA-6 standard) and can wipe the DCO hidden sectors.

Questions:

1. Will a Zero Write to all hard drive sectors do the same thing?

2. I read somewhere that BCWipe can wipe areas of a hard drive that a Zero Write to all hard drive sectors cannot wipe. If this is true, are there any known instances of Malware hiding in the areas that are not wiped with a Zero Write to all hard drive sectors?

Thanks in Advance.

I use Eraser so I don't have any experience with those. I have read that even if you do a Gutmann wipe the NSA can still get stuff off of it. I don't know if that is true just something I read on a tech blog one time.
