Hi there thangmap2002,
So your SSD, which I believe should be your OS drive, appears under My Computer while your HDD does not right?
In case this is a new HDD, you will need to go to Disk Management and initialize, partition and format it first.
How to initialize:

There is a link on how to partition and forma the drive at the end of this tutorial.
Keep in mind that this will erase the data stored on the drive. You shouldn't do that in case you have some data stored on it.
Let me know how this goes,
