Take your pick from: Data cable/connectors issue; Motherboard issue (both of my last two boards had connectivity problems, only detected long after construction); Drive firm/hardware (are you sure you can hear both of them working?); OS issue.
Change the cable. Buy a dock ( a reasonable quality one is less than the cost of the cheapest hard drive) and use each drive in turn on that to see if it fails outside the case. Not an infallible test, as it may be a problem specific to the case, like temperature.
