Apparently the computer was running from the single physical HDD with RAID, which does not make sense but I am not the person who originally installed the OS on this computer in 2013 or 2014. The contents of the HDD are not different Feb 03 00:01:39 because of the use of RAID because the RAID controller is hardware, not software. I cloned the HDD onto an SSD then connected the SSD to the normal SATA port on the motherboard instead of to the RAID controller by replacing the ODD in the computer with the SSD. There is no new computer, it is only the one, same computer but I wanted to replace the HDD with an SSD before the HDD fails.
