External hard drive no longer detected on MacBook Pro

My MacBook Pro froze and I have the spinning wheel. At that time I had my 2TB external drive mounted of which I have never had problems during multiple uses. I had to hold down power and just restart so I could get back on. Now, since then, my MacBook Pro no longer recognizes my external drive. Nothing comes up at all. I tried unplugging everything, restarting the laptop, trying different outlets, and trying every USB port. Nothing. My drive just keeps blinking white-colored light when plugged in. Now, I'm pretty sure nothing was updated in terms of software. It is a WD 2TB Drive.
