I plug my drive into my computer and the white LED turns solid but is not showing up on my MacBook Pro at all. Any suggestions?
What product are you using? The MBL doesn’t (usually) have a white light.

That’s an external drive, not a My Book Live. You should check in this forum instead: http://community.wdc.com/t5/External-Drives-for-Mac/bd-p/passport_mac
