Sure, and that's what my script does.

And how exactly does the script know what device name that drive will use 
*before* I put that "standard" label on it?  I've already shown that the 
device name the drive gets is quasi-random (race condition), and if the 
script guesses wrong I wipe out a drive in my RAID array!  :)

If I could get Seagate et. al. to put my "standard" disk label on the 
drive from the factory, I'd be golden.  But until they do, I need to make 
sure that the blank drive *before* initialization shows up in the right 
place.  And if I make that work consistently, then I don't *need* the 
label!  :)
