Hi, my single SSD shows two physical drive in my notebook and i tried deleting and combing them it doesn't work, it happened when i installed Linux Ubuntu on it while ago.
what you are seeing is called a partition.
Multiple partitions is normal.
So is not being able to delete and expand them at will without some preplanning.
What exactly are you trying to do? How many partions, what size, and what are they being used for?
