Aurora R4, Internal Hard disk not found

I keep getting this error when booting up my pc, says to reseat my hard drive. I have four identical hard drives and II reseated all of them. They are all being detected and identified in BIOS and I tried resetting the internal battery nothing worked. I have also reset the hard drives as well as checking all the boot options. Nothing I've read about has worked yet, I'm not sure if all four hard drives failed at the same time or not. Just wanted to see if there was something I haven't tried yet before I go buy another Hard drive because I'm real skeptical that all four died at once though it is possible. For the record I do not have another PC or anything I can use to test the drives elsewhere. If someone could help that would be greatly appreciated.
