BIOS recognizes second hard drive, but Windows 10 pro not
After a failed update, I had to reboot my computer and start a new. After Windows 10 loaded, it will not recognized my second internal hard drive of which it did prior to this entire system reboot. The second internal hard drive is a Toshiba DT01ACA100. My Dell is a XPS 8930. The second internal hard drive is recognized in the system BIOS, but it is not recognized by windows, not disc management, no does it show up in the device manager. Initially, I had it set to RAID ON, but tried the AHCI just to set if the different path would recognize the Toshiba hard drive. The Toshiba is already formatted with lots of data on it (which I need). Help PLEASE!
