New 3.0 passport WD drive

just bought new ultra WD 3.0 passport drive to use on new Macbook.

tried to do a WD diagnostics scan just to make sure all is in order. ran software and top portion showed the other WD drives I have tested and they passed. but the lower part of screen shows the usb port where I have new WD plugged in but i cannot access it.

the new drive is 3.0 and the usb port on my computer is 2.0…does that matter?

I also want to format the drive so I can read/write on mac…should I do that before running diagnostic test.

Hello,

Try formatting the drive so it can be usable on your Mac computer.
