WD Mypassport works - just not on my macbook pro

Hi All, I have a Western Digital 2TB external hard drive (My passport). About a few months ago I started having problems getting it recognized.

Sometimes it would show that two drives were visible. in the WD utility.

In frustration I attached it to my wifes new macbook air, and it works just fine. I erased the drive there and reformatted it, and pluged it in again, but helas, it does not work still.

Any ideas? A USB issue? Other things work on my USB port.

Before the High Sierra upgrade I was getting a corruption found on my macbook pro, but it is gone since the upgrade.

Thanks! M

MacBook Pro, macOS High Sierra (10.13.1)

Not necessarily.

Let's see if your MBP can "see" this drive in System Profiler, as follows:

Click on the Apple logo in the left side of the macOS menu bar.
Select "About This Mac"
Select the Storage tab. Does the drive appear here?
Select the Overview tab.
Select System Report...
Under the Hardware category, select USB.
On the right side, look under: USB Device Tree. You may need to expand any of the entries listed under this category. See if the My Passport shows up here ... does it? (Below is a screen capture of my drive to compare against.)

p.s. I see JimmyCMPIT jumped in. I suggest that you try my response first and if the drive does NOT show up, to go ahead and try his suggestions.
