Can't format 2TB Raid 0 My Book VelociRaptor Duo

I have a 2 TB Raid 0 drive setup (MyBook VelociRaptor Duo). I was trying to format it to wipe it completely clean but I’m getting an error in Disk Utility: “Erase process has failed. Press Done to continue.” In the details section it says “Name invalid. Operation failed.”

Any idea how to fix this? I tried good 'ole google without much luck. Tried erasing it from a different iMac and no luck as well. Even though the drive technically still works, I’m afraid to put any files on it because something clearly isn’t right with it if I can’t format it.

Don’t use Mac’s Disk Utility to try and change the RAID settings. Used the WD Drive utility for Mac
