Linux: BIOS Raid Metadata

There are four possible ways to erase Bios Raid metadata:

LINUX (May not work)

dmraid -r -E /dev/disk

dd if=/dev/zero of=/dev/sdb bs=1 count=16384

# If installing off the PXE server or CD Append the below to the end of the kernel command line and it will skip the error. 
nodmraid

# Known good: metadata appears to be at the end of the drive.
DEVICE=/dev/sdb
dd if=/dev/zero of=$DEVICE bs=512 seek=$(( $(blockdev --getsz $DEVICE) - 1024 )) count=1024

Windows

Load up a version of window and get a command line (shift + f10)

diskpart 
select disk [x] 
clean
