Unable To Make New Partition!

[Revolution]

Please help guys.
Don't know where should I post this.

I'm unable to make any new Primary or Extended partition on my 500GB SATA HDD.
I got 3 HDDs.

Disk0 80GB PATA
Disk1 500 SATA ( got yesterday.went to RMA.Certified Repaired Seagate HDD from Thiland)
Disk2 250TGB SATA(OS Windows XP Pro)

When ever I try to make new partition using windows disk management got only one option that is 'new volume'.
U can see the color is different.
I think accidentally make the HDD in software RAID ?
Got a massage(to recognize the new disk) when I connect the drive for first time but I just ignored and did not read that.

See the image:

Thanks.....

You made it dynamic. You need to convert it back to basic, like the other two.

Just R-Click on Disk1 and got option "Convert to Basic".
Sorry,I'm really noob.....
