The fact that the device mapper is getting involved with the drive leads 
me to believe that the drive was part of a raid, or at least configured 
by your raid controller at one time and there is now a superblock on it 
that is messing up everything.
You'll probably need to zero out that superblock before things will 
start to behave correctly.
