    I was laying in bed and heard my computer restart for seemingly no reason. I get up to look at the screen and I get the error "3rd Slave Hard Disk Error" I try to continue but since Ubuntu is installed on the now faulty hard drive, it says error: no such device: - device name - Entering rescue mode - grub rescue>... which I've seen before, it's telling me that it can't find the Ubuntu installation. I have windows as my primary OS on the first hard drive (the one that's still detected) and manually choose windows before the computer starts. I went into BIOS to try and change the boot sequence, which has caused the grub rescue screen before, but the 2nd hard drive is no longer detected. How can I get passed the grub rescue screen? What could of possibly happened to my hard drive in such a seemingly random way? I have a 3rd unused hard drive, am I better off just installing windows on it and starting over? I don't want to lose everything on my 2nd hard drive though.

    I tried starting it with the cords plugged into the primary hard drive into the 2nd faulty one, it's spinning but still not detecting it

    For over 20 years now, all hard disk drives have been intelligent devices that keep numerous items of information in a hidden area called the "system area" If, for whatever reason, the drive's controller (also on the drive) cannot read from that system area or its contents have become corrupted, the drive never comes ready and does not report its existence to the PC. It seems to me that has happened to the drive you are asking about.
    There are some tricks that may get it to reappear temporarily; but, regardless, there is absolutely no way to permanently fix it.
