HARD 2 Get INTO THE HARDWARE

Hi,

:stars: I have a Mem.Stck having 2GB capacity and want to make it 2 partition. I tried using the Xp's Disk Management feature but the option to Delete partition is grayed out so that I can't partition it as I wish. however the Previous mem.stick I had is still showing and allowing me to delete and recreate partition. what's the problem andhow do i rectify that. ( I tried a number of Partition tools but no success:stars:

Who make this Mem.Stck? What model?
