Ghost WD drive, and strange power

The wire to my drive enclosure is frayed a bit, housing a 2tb WD enterprise drive.

The drive has stopped mounting, but my disk utility on my mac still sees the drive. It does not want to mount.

Freaking out, I tried throwing a 600gb seagate in the enclosure. It mounts but I cannot access anything. It's about 10 years old.

I've ordered a new enclosure assuming its a power supply issue. My question is that if I'm correct, why are these drives registering at all? Why does the first not even mount, and the second show me a directory I cannot access, or read write to?

Do I possibly have this wrong? Thanks.

Welcome to the TH community, JZesbaugh!

I'd recommend you to try using a SATA-to-USB cable + an AC adapter and see if that will help you access the HDDs externally. If not, maybe finding a PC where you can physically mount the WD enterprise drive internally (via SATA) will help you detect it.
Since the Disk Utility is actually recognizing it, you should try testing the drive for defects from there.

Let me know how the troubleshooting is going! Good luck!

Thanks, for replying. It's very strange never seen it before. I'm hoping its the SATA bridge that is just wonky. Enterprise class drive with cheap enclosure. But the different symptoms with two different drive in the presumably broken enclosure have me stumped.

My thought was a power supply issue would not let anything happen, but in this case it seems that they are "half working". Very bizarre.

Yes, indeed, it does sound weird to me as well.
That's why I'd suggest you find a PC where you'd be able to connect both HDDs via SATA internally and see how they will get recognized there. You could do this until the new enclosure arrives. Of course, you might not be able to access your data due to the different file system. However, at least you will be able to determine the source of the issue.

Keep me posted! :)
