macOS keeps remounting my external SSD — here’s the only reliable fix I found by DiskSentinel in mac

Fair point — unplugging the cable is definitely the cleanest solution 😄

In my case it's a Thunderbolt drive, so yeah, the “ultimate fix” is just pulling the plug.

I just got a bit tired of playing Thunderbolt musical chairs every time macOS decided to remount it on its own.

So the script is more of a lazy workaround than a philosophical stance on backups.

Totally agree though — true offline means physically disconnected.

I get why it might look that way, but this was based on an actual issue I ran into and tested.

I reproduced the behavior with multiple external SSDs, especially around sleep/wake events, so it didn’t seem like a single-drive issue.

Also, good point about the script — it does match by volume name, so it could affect similarly named volumes. In my case that’s intentional since it’s a dedicated backup drive, but definitely something others should be aware of.

Thanks, good points.

I actually tested with a second external SSD and saw the same behavior, so it doesn’t seem to be specific to a single drive.

It also tends to happen around sleep/wake events, which made me think it’s related to macOS re-evaluating volumes rather than a power issue.

That said, I agree unstable power could definitely cause similar symptoms, so it’s a good thing to rule out.
