I want to do a quick "wipe" of some disks so they look like they're ready to be newly partitioned. Currently there is a GPT partition type on disk, which seems to write some data both at the beginning and end of the disk. In this case, it doesn't matter if the data on the disk is wiped, so no need to wait for the whole disk to dd from /dev/zero. So what's a simple way to clear just the beginning and end GPT headers?
In this case, I'm using Linux (CentOS 7) with standard SATA disks (/dev/sda, etc.)
