I create a dummy partition with type 'da' (Non-FS-Data) on my HDDs.
Altough 0 (Empty) sounds nice too. ;-)

I say dummy partition because i don't actually use the partition for 
anything. It's only there to stop my encryption init-script, so that i 
don't accidentally kill an already initialized HDD (or one of the 
system-HDDs) in case i fat-fingered the device-name.
