3TB Drive Crashing Mac Mini

It. Worked the first day without any problems on the macbook pro and i never hooked it up to the mini. The next day i hooked to the mini and kept crashing it and then i hooked it to the macbook pro and it started crashing that day. So installed the western digital drivers and it fixed the macbook pro but not the mini and i always safely eject as long as it is not crash.
