RAID syncing 2 partitions

Hi all,

I tried setting up RAID between 2 partitions and it was success.
If I write some things on /dev/md0, both partition got affected.

Then I stop the RAID, and I mounted one of my partition and I created a file in it.

Now I started the RAID (mdadm --assemble --scan)

What I expected is the another partition should also have the same file. But it was not there.

Why it is not there?? Any special commands available???
