Converting Raid Harddrives Back to NTFS with Software Tools

My computer battery was replaced by a family member and when I boot up my PC which took about 10 minutes instead of 30 seconds. I noticed that the 2 harddrives were displayed in the bios as raid drives. The 2 harddrives are SATA. However in Windows when I right click on My Computer and select Manage then Device Manager they appear as NTFS format.

I sure that this configuration has something to do with response.

I would appreciate any suggestions on how to restore my raid drive back to 2 harddrives under NTFS without loosing my data. I would prefer a software tool or a step by step solution since I am not comfortable with manually making changes to computer settings.
Thank you for your advice in advance to this frustrating problem
