USB Hard drive has very small chance of being recognized by Macbook Pro each time it is connected, but works with other machines I have a WD "My Passport" 1TB external hard drive. It isn't recognized by my Macbook Pro (retina, 2013) or a friend's very similar model, but it works with every other machine I've tried, including two Linux netbooks and an older iMac. 

Sometimes, it mounts after multiple tries unplugging and replugging the cable. Usually, the hard drive spins up and lights its status LED, but it is not mounted or recognized by Disk Utility or the diskutil list command.

This question seems to describe a similar issue, but their drive doesn't connect every few dozen attempts like mine does.

What could be causing this issue?

Edit: When the drive is plugged in, this is output to dmesg:

Edit 2: That output is still displayed when connecting a working flash drive, along with other stuff about USB media and about filesystems. It is not unique to the drive in this question, but it is the only thing outputted when this drive is connected.

Edit 3: So I did in fact have openZFS installed, at least partially. (No idea how or why). After running their uninstall script, nothing is output when this drive is plugged in at all. 

Edit 4: Connecting with an ordinary MicroUSB cable instead of a USB 3 cable works every time. I realized that every other device I tested it on that worked didn't support USB 3. I just tested it with a Windows device that supports USB 3, and while it is better than the Mac, it still has a problem recognizing the drive. Interestingly, the Windows computer shows the drive as not supporting USB 3.0.
I had the same issue with a WD Elements 2.5" 2TB disk on my retian macbook with macOS High Sierra.

My assumption is that the disk "fell" off the USB bus and macOS instead of gracefully retrying is just giving up.

In my case the disk worked for an hour or two, but then I got the error that I should eject Disks before unplugging them and the errors in the dmesg.

I guess this is a combination of macOS being not very forgiving and the WD on-disk USB controllers being a little wonky.

I was using a USB3 hub between the macbook and the disk, so maybe that was the source of wonkyness.

I have no ZFS drivers installed.
