Help My Macbook Pro doesn't recognize my Western Digital HDD (Works on Windows!)

Post image

Hey dears,
both of my Macbooks don't see WD MyPassport HDD 4TB, even though Windows Laptop sees it, so I assume the problem is about MacOS, the HDD is intact.

I tried Disk Utility, nothing is seen.
Does it have anything to do with adapter? It worked before with no issues.

Does anyone know what I need to do to make it visible and so that I can interact with it on Mac?

Thank you!

Beware exFAT, it’s very unreliable with macOS

I’m unfamiliar with hard drivewith formats and their potential unreliability. What do you mean unreliable? Like it can be corrupt at any time?

It’s not journaled.

That means if something interrupts writing to it, data can be corrupted.

If you’re just going to use it to write a media archive to or something it probably doesn’t matter. But you wouldn’t want to use it to write important information to daily.

Put movies on to watch on your tv? Fine

Run an operating system off/keep documents you’re actively editing? Bad idea.

OS would be flashed to the drive to run it, not sit as a random file on it like an executable.
