I would use WD's Digital Lifeguard utility
to write 0s and 1s to the HDD. I haven't used it on a 2TB HDD, but it didn't take too long on a 500GB HDD.
Is this free?
My hard drive has a few applications on it that are linux based. I want to erase all of that and then put a couple of new linux applications onto the drive.
Perhaps the Darik's boot and nuke(DBAN) is not the best application for me to be using. I would also be open to looking at any other applications that would work here.
Can I do this with Microsoft windows and my external adapter cable?
