I've got a Mid 2015 MacBook Pro running Monterey. A WD 1TB My Passport quit being recognized by the system after several times of inadvertently being unplugged without ejecting. It's got a micro usb connection that would fall out a lot. The drive lights up and whirrs when connected and the light stays solid but I can't see the drive. Here's what I've tried.

  • A different external drive works
  • Tried a different USB cable
  • Tried different USB port
  • Tried it on another computer w/ same result
  • Enabled see external disks
  • Looked for it in Disk Utility but it doesn't show up.
  • Looked for it with Terminal list command but it doesn't show up Rebooted
  • Upgraded to Monterey
  • Tried WD Utilities
  • Removed it from external casing to plug in more directly but still is via usb micro interface. Not sure how to put it into another enclosure or interface.
  • Tried to manually force quit the fsck process from activity monitor but there is no fsck process running.
  • Downloaded a couple of different recovery programs Recoverit and Easus and it's not recognized. It did show up with Easeus twice but when I tried to search the disk it spontaneously dropped/disconnected after 2 - 3 minutes.

Of course the files on their are not backed up. I was working my way towards that over the next few days. Anyway I'd like to get at them. I know data recovery would seem to be my next step but I thought I'd reach out to see if anyone had any other suggestions/recommendations. It seems the issue is from the frequent disconnecting without ejecting but I'm not sure what else to try.

Here is what terminal spit out when I put in that code.

The default interactive shell is now zsh.
To update your account to use zsh, please run `chsh -s /bin/zsh`.

  • First let's see if the system sees anything on USB. With your drive connected, please add a code block to your original question containing the output of the following command: system_profiler SPUSBDataType

  • macOS complains a lot about disconnecting storage without ejecting first. It's more of an "I want to be sure everything is written to the drive first before you pull the plug" in my experience. The very few times I could ever trace a drive problem to that disk utility or diskwarrior could easily fix the problem. More likely unplugging was coincidental and the drive was already failing. But @Pion is right, lets get a look at what the Mac sees on USB when it is plugged in. Dec 7, 2021 at 20:46
  • Thanks for the response guys. I edited my post to include the output from that command.

  • Interestingly enough, macOS recognizes the drive. What is the output of ls -la /Volumes?

  • This is what I get. I ran the system profiler command again since something looked wonky and now the drive doesn't seem to show up. I posted the result in the original post.

From our exchange in comments, we've seen that your visible symptoms are caused by the drive falling off USB. Given your earlier debugging findings:

  • A different external drive works
  • Tried a different USB cable
  • Tried different USB port
  • Tried it on another computer w/ same result

it's clear that this is a problem with the WD My Passport, not your Mac or cable.

The next question is whether the issue inside the WD lies with the hard disk (HDD) itself or with the USB interface controller that it's attached to.

You will need to fully disassemble your WD in order to extract the HDD and attach it to a different USB interface controller, which you'll have to buy.

If I were you, I'd contact WD support first. This is their bug and they should repair or replace your drive. If you're out of warranty, then go ahead with the above troubleshooting step.
