I'm trying to create a Raid array and these are the errors I keep getting. I have repartitioned the drives several times.

root@BitchStewie:/dev# sudo mdadm --verbose --create /dev/md1 --chunk=64 --level=0 --raid-devices=12 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1 /dev/sdg1 /dev/sdh1 /dev/sdi1 /dev/sdj1 /dev/sdk1 /dev/sdl1 /dev/sdm1
mdadm: super1.x cannot open /dev/sdb1: Device or resource busy
mdadm: ddf: Cannot use /dev/sdb1: Device or resource busy
mdadm: Cannot use /dev/sdb1: It is busy
mdadm: device /dev/sdb1 not suitable for any style of array
