And putting a partition table in your array does exactly what to help

Which is why I partition my disk. I use one raid for the OS, and 
another for my data.

but than "fdisk -l" shows partitions - what the hell.....
that above you responded to has no partitions but the whole drive for 
the RAID

Yup - the raid sits directly on top of the hard drive - AND IS ITSELF 
PARTITIONED.

Both of those are not normal - it is not normal for a raid to sit on 
bare drives, and it is not normal for a raid to contain partitions.

(Although there's nothing actually wrong with either :-)
