I dropped off my computer to be set up at Staples. I had purchased two brand new Seagate SATA drives and wanted to run RAID with with striping. I just picked up my computer this morning and for some reason when I start up my computer it says that it is running RAID with striping and has 1 GB of hard drive space which is normal. However, when I go into My Computer, I see that there are two HDDs. Is this normal??
